The last known dinosaurs that roamed the earth lived during the Cretaceous period, between 145 million to 66 million years ago. It is believed that a catastrophic event known as the Cretaceous-Paleogene extinction event wiped out nearly all dinosaurs, along with many other species of plants and animals.
This extinction event is thought to have been caused by a combination of factors, including massive volcanic activity and an asteroid impact.
Despite the extinction event, however, some species of dinosaurs may have survived for a short time afterwards. For example, recent studies suggest that non-avian dinosaurs may have persisted for a few hundred thousand years after the asteroid impact, before finally going extinct.
Interestingly, modern-day birds are considered to be the closest living descendants of dinosaurs. While they are not technically classified as dinosaurs, birds share many similarities with their ancient ancestors, including their bone structure, skeletal system, and even some of their behaviors. So, in a sense, we can say that some form of “dinosaurs” did survive, and indeed still thrive, on our planet today.

Is there still one dinosaurs living today?
No, it is widely believed that all dinosaur species became extinct around 66 million years ago due to a catastrophic event, possibly a massive asteroid impact. While some scientists have proposed the idea of “living dinosaurs” based on the similarity between modern birds and their dinosaur ancestors, the truth is that no known dinosaur species still exists today.
The fossils found by paleontologists are the only evidence left of the once-great group of reptiles, which roamed the Earth for millions of years in a variety of forms and sizes. While it is fascinating to speculate on the possibility of encountering a living dinosaur, the reality is that we are unlikely to ever see one in the flesh, as they belong to a time long past.
Nevertheless, we can still learn about these impressive creatures through the study of their fossils, and appreciate the incredible diversity of life that has existed on our planet throughout its history.
What two dinosaurs died together?
There isn’t a definitive answer to this question, as the fossil record doesn’t always provide clear information about exactly how or when dinosaurs died. However, there are a few examples of dinosaur fossils that have been found in close proximity to each other, suggesting that they may have died together.
One such example comes from the Gobi Desert in Mongolia, where a pair of Velociraptor skeletons were discovered. These two dinosaurs were found lying near each other, and it’s possible that they died in some sort of struggle or fight.
Another potential example of dinosaurs that died together comes from a site in Colorado known as Dinosaur Ridge. This site contains numerous dinosaur fossils, including those of Allosaurus and Stegosaurus. In one area, several Allosaurus skeletons were found in close proximity to each other, and it’s possible that they died while hunting or scavenging together.
Similarly, a group of Stegosaurus skeletons were found in another area of the site, and it’s possible that they died together due to illness or some other cause.
While it’s difficult to say for certain which two dinosaurs died together, there are definitely examples of dinosaur fossils that have been found in close proximity to each other. These fossils provide us with valuable information about how these ancient creatures lived and interacted with each other, and continue to fuel our fascination with the world of dinosaurs.
Has a full T. rex been found?
The answer to whether a full T. rex has been found is a bit complicated. While there have been numerous discoveries of Tyrannosaurus rex fossils, finding a complete skeleton of this dinosaur is rare. To date, there has never been a 100% complete T. rex skeleton found in one excavation site.
Typically, when scientists unearth T. rex fossils, they find scattered bones or a partial skeleton. In some cases, paleontologists have been able to reconstruct a full T. rex skeleton through the combination of multiple excavations and bones from different individuals.
Some of the more famous and nearly complete T. rex skeletons include “Sue,” the largest and most complete T. rex ever found, and “Scotty,” another large and well-preserved specimen. However, even these specimens have some missing bones or require reconstruction.
Finding a complete T. rex skeleton would be a monumental discovery for paleontologists. With a full skeleton, scientists would have a better understanding of the dinosaur’s anatomy, behavior, and evolution. However, it is unlikely that a complete T. rex skeleton will be found anytime soon, as the odds of such a discovery are low due to the nature and rarity of fossilization.
Did T. rex lay eggs?
Yes, Tyrannosaurus rex did lay eggs. T. rex was a member of the dinosaur group called theropods, which were bipedal, carnivorous dinosaurs that included other famous species such as Velociraptor and Allosaurus. Like all dinosaurs, T. rex reproduced by laying eggs, which were fertilized by a male through mating.
Paleontologists have found several fossilized T. rex eggs, although they are relatively rare. The eggs are oval-shaped and about the size of a cantaloupe, with a textured surface that would have allowed for gas exchange between the developing embryo and the outside world. The texture of the eggshell also suggests that the eggs were buried in sediment, which protected them from predators and helped maintain a constant temperature.
T. rex eggs would have taken several months to hatch, and the young would have emerged as tiny versions of the adult dinosaur. The hatchlings were probably covered in fluffy feathers, which would have helped protect them from the elements and regulate their body temperature. As juveniles, T. rex would have grown rapidly, eventually reaching their full size of around 40 feet long and 12,000 pounds.
The discovery of T. rex eggs provides valuable insight into the biology and behavior of this iconic dinosaur. It is clear that T. rex, like all dinosaurs, went through a complex and fascinating lifecycle that involved laying eggs and nurturing their young.
How many T. rex are left in the world?
Rex or Tyrannosaurus Rex are extinct dinosaurs which lived on earth about 68 to 66 million years ago. It is impossible for any T. Rex to exist today because they went extinct long before humans came into existence. Therefore, there are no T. Rex left in the world in the present times.
However, the T. Rex remains, including fossils, skeletons, and bones have been discovered and preserved for research and exhibition purposes. Paleontologists continue to study the remains to learn more about these fascinating creatures from the distant past. In 2020, during the Covid-19 pandemic, researchers discovered fossils of a new species of T. Rex in Montana, USA.
Interestingly, the fossils suggest that T. Rex species existed in freshwater ecosystems too.
It is crucial to understand that T. Rex are extinct and there are no living T. Rex on earth. While it is a fascinating thought to imagine the existence of a creature as mighty as T. Rex, it is merely a fantasy. However, the study of T. Rex and other dinosaurs is essential in enhancing our understanding of the earth’s history, evolution, and biodiversity.
How did T. rex go extinct?
The extinction of Tyrannosaurus rex, commonly known as T. rex, remains a mystery that is still being studied by paleontologists to this day. However, there are several possible explanations for the demise of this iconic predator that ruled the terrestrial ecosystem during the Late Cretaceous period.
One of the most popular theories is that T. rex went extinct as a result of the asteroid impact that occurred approximately 66 million years ago in what is now the Yucatan Peninsula of Mexico. The impact caused a global cataclysmic event, including massive volcanic eruptions, wildfires, and a sudden climate change that led to a drop in temperature and a reduction in available resources.
This event is believed to have wiped out approximately 75% of all species on Earth, including the dinosaurs.
Another theory suggests that the extinction of T. rex, along with other dinosaurs, was caused by a prolonged period of volcanic eruptions that occurred in what is now India. These eruptions occurred over a span of several hundred thousand years and resulted in massive environmental changes, including an increase in atmospheric carbon dioxide levels, which caused global warming and ocean acidification.
This theory proposes that the environmental changes caused by the volcanic eruptions made life unsustainable for many species, including T. rex.
Climate change is another potential factor that could have contributed to T. rex’s extinction. The Late Cretaceous period saw significant changes in global climate, including a shift towards cooler and drier conditions. This change in climate could have had a devastating impact on the vegetation that T. rex relied on to survive.
Lastly, some researchers speculate that competition for resources, particularly with other large predators, may have played a role in T. rex’s extinction. Fossil evidence suggests that T. rex lived at the same time as other big carnivores, such as the Triceratops and the Ankylosaurus. These animals may have competed with T. rex for food and other resources, ultimately leading to the T. rex’s demise.
The extinction of T. rex remains a fascinating mystery that continues to be the subject of ongoing research and speculation. While there is no definitive answer, it is likely that a combination of factors, including a catastrophic event like an asteroid impact, a prolonged period of volcanic eruptions, climate change, and competition for resources, played a role in bringing about the end of this once-mighty predator.
Will the T. rex come back to life?
The possibility of reviving the T. rex or any extinct animal is a controversial topic in the scientific community. While there have been notable scientific breakthroughs in recent years in the field of genetic engineering and cloning, there remain significant barriers to the resurrection of the T. rex.
One of the primary obstacles in reviving the T. rex is the degradation of DNA over time. The T. rex has been extinct for around 66 million years, and there is a high probability that the DNA is not well-preserved enough to enable successful cloning. Furthermore, researchers have not yet been able to reconstruct the entire genome of any extinct species, let alone the enormous genome of the T. rex, which would require significant advancements in technology.
Even if the DNA is preserved enough to attempt cloning, scientists would require a surrogate mother to incubate the fertilized egg. The T. rex was a reptile, and reptilian eggs have different developmental mechanisms than mammalian eggs. Finding an available surrogate mother for a T. rex would be a challenge, as would the challenge of collecting viable eggs to fertilize.
Lastly, the ethical considerations of reviving extinct species cannot be ignored. While there is great interest in seeing what a T. rex looked like and how it behaved, reintroducing an extinct species into the modern world could have dire consequences. The habitat and ecosystems of the world have been altered extensively since the T. rex’s time, and reintroducing an apex predator into these environments could cause significant harm to the existing creatures and balance of the ecosystem.
Therefore, while the concept of reviving the T. rex is an intriguing possibility, it is unlikely to happen, and even if it did, there are significant ethical, practical, and scientific considerations to take into account. The T. rex, along with other extinct creatures, remains extinct, and our focus should be on preserving endangered species and their habitats.
Could dinosaurs survive today?
No, dinosaurs couldn’t survive today. Dinosaurs lived in a dramatically different environment than the one we exist in today; they lived in a far more diverse and expansive prehistoric world. Dinosaurs lived in forests, deserts, and swamps, among other environments which no longer exist due to the changing climate and land formations.
In addition to enduring a much different environment, dinosaurs faced many other barriers to their survival such as the food supplies. For example, the food dinosaurs ate could have easily become extinct or been altered due to changes in the environment, meaning that it could have no longer provided a sufficient source of nutrition for the species.
Also, it is important to note the evolutionary shift that has occurred in other species which cannot compete or are no longer fit for the current environment. Dinosaurs, like many other species from their time, were unable to adapt their biology and anatomy to their current environment.
Lastly, dinosaurs would need to have some sort of defense system, such as armor and/or a strong set of defense mechanisms such as large horns and claws in order to protect themselves from predators, both large and small.
With the drastic changes in the environment and the lack of armor and protection, it is clear that dinosaurs would not be able to survive in the environment today.
Why did birds survive but not dinosaurs?
The survival of birds and the extinction of dinosaurs can be attributed to several factors. Firstly, it is important to understand that birds are not just direct descendants of dinosaurs but evolved separately from a common ancestor. Based on various studies, it is believed that birds evolved from small, light-weight theropod dinosaurs that survived the mass extinction event 65 million years ago.
One of the major factors that contributed to the extinction of dinosaurs was a catastrophic event that occurred around 65 million years ago when a massive asteroid is believed to have struck the earth. This had a severe impact on the environment and led to a dramatic change in the climate. The impact resulted in widespread fires, tsunamis, and a “nuclear winter” effect that blocked out the sun, causing global temperatures to drop significantly.
The dinosaurs were unable to adapt to these changes and ultimately perished. However, certain species of birds were better equipped to adapt to the changing environments and survived this mass extinction event.
Another factor that contributed to the survival of birds is their ability to fly. Flight gave them a strategic advantage, allowing them to escape predators, find new sources of food, and explore new territories. This capability allowed some bird species to migrate to other regions that were not affected by the mass extinction event, which helped them escape extinction.
Furthermore, birds had the advantage of evolving faster than their dinosaur ancestors. This means that they were able to adapt to new and changing environments more quickly, allowing them to survive drastic climate change events that occurred over millions of years. In contrast, some dinosaur species were unable to adapt quickly enough or were outcompeted by other, more adaptable animals.
The survival of birds and the extinction of dinosaurs can be attributed to a combination of factors, including the ability to fly, evolutionary adaptability, and a bit of luck. These factors allowed birds to survive the mass extinction event, thrive and evolve into the diverse species we observe today.
How many actual dinosaurs have been found?
Since the discovery of the first dinosaur fossil in 1824, paleontologists and scientists have been working tirelessly to uncover, study and categorize various dinosaur species. Over the years, they have unearthed a vast array of dinosaur remains, ranging from complete skeletal structures to smaller fragments and fossilized tracks.
The exact number of actual dinosaur fossils that have been found is difficult to estimate, as new discoveries are made every year. Despite this, it is believed that over 700 distinct dinosaur species have been identified since the first fossil discoveries were made.
The process of identifying and categorizing dinosaur fossils is not an easy task, as many of the remains are incomplete or damaged. To get a better understanding of these creatures, paleontologists often have to use their knowledge of other related organisms, fossils and geology to infer a dinosaur’s likely appearance and behavior.
Additionally, the locations where dinosaur fossils are found vary greatly, with discoveries being made on every continent. Some regions, such as the Badlands in North America, the Gobi Desert in Mongolia, and the Patagonian region of South America, are known to be rich in dinosaur remains, and many species have been discovered there over the years.
It’s important to note that while dinosaur remains are fascinating and provide us with incredible insights into Earth’s history, they make up just a small fraction of the total number of organisms that have lived on our planet throughout its history. Nevertheless, the discovery and study of these ancient creatures continue to be a vibrant and exciting field of scientific research, one that continues to yield new and fascinating discoveries even today.
Did any dinosaurs give live birth?
The common perception is that all dinosaurs laid eggs, but recent studies and research have shown that some may have given live birth. The first evidence of live births in dinosaurs was discovered in the form of a fossil of a pregnant mother and her unborn offspring in China in 2004. The fossil belonged to a small dinosaur called a Lufengosaurus, which lived during the Jurassic period, about 200 million years ago.
Further research and studies have found evidence of more dinosaurs giving live birth. Scientists have found that a group of herbivorous dinosaurs, called ornithischians, which includes some of the most well-known dinosaurs like Triceratops and Stegosaurus, may have given live birth. These dinosaurs had a unique reproductive system, which included a specialized bone called the pubis, that allowed them to carry their babies inside their bodies for an extended period similar to mammals.
This suggests that they might have given live birth or laid soft-shelled eggs.
On the other hand, some researchers argue that there is no clear evidence to support live birth in dinosaurs. They suggest that the fossilized embryos of some dinosaurs found in eggs might simply have been near to hatching from eggs when they died.
While the debate on whether dinosaurs gave live birth or not is still ongoing, recent discoveries and evidence suggest that some dinosaurs may have given birth to live young. The findings underline the fact that dinosaurs were much more diverse and unique than previously thought, and provide a valuable insight into the reproductive behavior of dinosaurs.
What existed before dinosaurs?
Before the dinosaurs, there were various forms of life that inhabited the Earth, some of which were still around during the time of the dinosaurs. These life forms included plants, insects, fish and other marine life, as well as various types of reptiles and amphibians.
One of the most notable groups of animals that existed before dinosaurs were the therapsids, which were a type of mammal-like reptile. They were diverse in size and shape, with some being small and rodent-like while others were massive and heavily-armored. They were also the dominant land animals during the Permian period, which ended around 252 million years ago.
Another group of animals that existed before dinosaurs were the archosaurs, which were a diverse group of reptiles that included the ancestors of crocodiles and birds. One particular type of archosaur, called the Pterosaurs, were flying reptiles that lived during the Mesozoic era, alongside the dinosaurs.
Various species of plants also thrived before the age of the dinosaurs, including ferns, cycads, and conifers. These plants played a vital role in the ecology of the ancient world, serving as the primary food source for many animals and contributing to the overall health of the environment.
The world before the age of the dinosaurs was a diverse place inhabited by a wide variety of animals and plants. While the dinosaurs may have been the most well-known inhabitants of the ancient world, they were by no means the only ones, and their existence was preceded by millions of years of evolution and adaptation among other forms of life.
Will dinosaurs ever exist again?
The short answer is that it is highly unlikely that dinosaurs will ever exist again. Dinosaurs ruled the Earth for about 165 million years, but were wiped out by a catastrophic asteroid impact around 66 million years ago. Since then, no dinosaur fossils have been found that are less than 66 million years old.
While scientists have been able to extract genetic material from some extinct species, such as the woolly mammoth, the oldest dinosaur fossils are too old and too degraded to yield any usable genetic information. Even if scientists were able to piece together a complete dinosaur genome, there are many practical challenges to actually bringing dinosaurs back to life.
One approach that has been suggested is to use the genome of a closely related species, such as a bird, and modify it to resemble the genome of a dinosaur. However, even if this were possible, it is not clear whether the resulting organism would actually be a true dinosaur, or simply a bird with some dinosaur-like traits.
Another approach that has been suggested is to use cloning to create a living dinosaur from preserved tissue samples. However, this approach would be extremely challenging given the age and degraded state of the dinosaur tissue samples that have been recovered to date.
In addition, even if it were possible to bring a dinosaur back to life, there are ethical considerations to consider. Dinosaurs were not designed to live in the modern world, and it is not clear whether it would be ethical to subject a cloned dinosaur to a life in captivity.
While it is an interesting question to consider, it is highly unlikely that dinosaurs will ever exist again. The challenges associated with extracting usable genetic information from ancient fossils, as well as the practical and ethical challenges associated with actually bringing dinosaurs back to life, make it a highly unlikely scenario.
Do dinosaur eggs exist?
Yes, dinosaur eggs did exist. Dinosaur eggs have been found all over the world, especially in regions that were once home to different species of ancient dinosaurs. These fossilized eggs range in size from that of a chicken egg to the size of a football, depending on the species of dinosaur that laid them.
Dinosaur eggs were first discovered in the 19th century and since then, thousands of eggs and nests have been found in various parts of the world. The discovery of dinosaur eggs has been instrumental in helping scientists understand the behavior and anatomy of various dinosaurs. For example, scientists have been able to determine the size of female dinosaurs based on the size of the eggs as well as better understand how dinosaurs cared for their eggs and young.
The preservation of dinosaur eggs and nests can vary greatly. In some cases, the eggs and nests are well-preserved due to unique environmental conditions such as being buried quickly in sand deposits. In other cases, the fossils may have been damaged or destroyed due to weathering, erosion, or exposure to the elements over time.
It is important to note that not all dinosaur eggs were the same. There were several different species of dinosaurs and each species had its own unique characteristics, including differences in the size, shape, and structure of their eggs. For example, the eggs of some species of dinosaur were elongated while others were more round in shape.
Additionally, some dinosaur species laid their eggs in nests while others laid their eggs in burrows or other types of environments.
Dinosaur eggs did exist and have played an important role in helping scientists better understand the behavior and anatomy of ancient dinosaurs. While fossils of dinosaur eggs can be found all over the world, their preservation can vary greatly, making it important to carefully study each fossil to gain a better understanding of the dinosaur species that laid them.
