No, cockroaches did not live with dinosaurs. Cockroaches are members of the insect order Blattodea, which evolved alongside the dinosaurs in the Mesozoic era, some 250 million years ago. However, it wasn’t until the extinction of the dinosaurs about 65 million years ago that the first true cockroaches began to appear.
While it has been suggested that the earliest species of cockroach were likely quite simple creatures that lived in the tree canopy and were not closely related to modern cockroaches, the modern cockroach species hypothesized to have evolved from them appeared after the dinosaurs went extinct.
It was approximately 40 million years ago that the by-then more modern and versatile types of cockroaches began to appear in the fossil records. So, in summary, cockroaches did not live alongside dinosaurs, but rather evolved after their extinction.

How did roaches survive?
Cockroaches have managed to survive due to a variety of factors. Their ability to adapt to different environments and eat a wide range of foods has enabled them to survive for hundreds of millions of years.
Their hardy exoskeletons help protect them from predators and their ability to reproduce rapidly allows them to quickly bounce back from any population loss. Additionally, cockroaches are able to go without food or water for long periods of time, and they can live in temperatures that would be deadly to many other species.
All of these factors combined make it no surprise that roaches have been here for so long and will likely continue surviving for many years to come.
What is the oldest insect?
The oldest insect fossil is a Rhyniognatha hirsti, which is a type of wingless fly. This ancient creature was estimated to be about 407 million years old, and lived during the Late Silurian period. This insect would have been much smaller than modern insects, only about 2 – 4 millimeters long.
It was found in Scotland in the 1960s and was the first insect ever to be discovered with a complete exoskeleton. Other ancient insects, including some 300 million year old archaic moths, have also been found, but the Rhyniognatha hirsti is the oldest known insect fossil.
When did cockroaches first exist?
Cockroaches are one of the most common pests found in households and businesses today, but they have been around for much longer than you might expect. According to fossil records, cockroaches have been on the planet for at least 300 million years and may have even been around during the time of the dinosaurs.
The oldest fossilized roach dates back about 140 million years and is believed to be the ancestor of all modern cockroaches.
Cockroaches are actually among the most evolutionarily successful creatures on the planet and they have had plenty of time to perfect their method of survival. Their evolution is so successful and resilient that they can exist even in the worst natural disasters and conditions.
In fact, there are nearly 5,000 species of cockroaches all over the world, each with its own unique adaptations and behavior. Many of these species have even found ways to thrive in the cold climates found in the higher latitudes.
Given the longevity and evolution of cockroaches, it is clear that they have been impacting the world for a very long time. It is likely safe to say that cockroaches have been around for millions of years, long before humans appeared on the planet.
What came first cockroaches or dinosaurs?
It is impossible to know for sure which came first, cockroaches or dinosaurs. Cockroaches are considered to be the oldest insects known to inhabit the earth, and they have been around since the Carboniferous period which dates back approximately 280 million years ago.
Dinosaurs have been around since the Triassic period which dates back approximately 230 million years ago, so some scientists argue that dinosaurs came before cockroaches. However, the exact timing of when cockroaches and dinosaurs first evolved is still unknown, so there is no definitive answer as to which one came first.
Will cold weather kill cockroaches?
No, cold weather alone will not kill cockroaches. Cockroaches are resilient creatures, able to adapt to a wide range of temperatures, so cold temperatures alone won’t be enough to kill them. That said, cockroaches do require warmth and moisture to survive, so extreme cold and/or lack of moisture can make their environment hostile, leading to slower movement, reduced appetite, and ultimately, death.
Additionally, extreme cold may lead to injury for roaches, as their exoskeletons are not well-suited for frigid temperatures. However, it is important to note that most species of cockroaches are capable of surviving temperatures of 18°F for several hours, so even in cold climates, the pests may find enough warmth to thrive.
How big were cockroaches 300 million years ago?
It is difficult to answer this question as it is not known exactly how big cockroaches were 300 million years ago. The oldest fossilized cockroach is said to be approximately 320 million years old, which puts it relatively close to 300 million years ago.
However, the fossilized roach is incomplete, making it impossible to determine its size. In general, cockroaches have remained the same size throughout the last 200 million years. The smallest species tended to be around 0.3 – 0.4 inches, while the largest species reach around three inches in length.
Thus, it is safe to assume that cockroaches 300 million years ago were similar in size to today’s cockroaches.
Were there cockroaches in the dinosaur era?
No, there were not cockroaches in the dinosaur era. Cockroaches are believed to have evolved from the Carboniferous period, which came after the dinosaur era. Therefore, cockroaches did not exist during the Mesozoic era, which includes the dinosaur era.
The Mesozoic era is divided into the Triassic, Jurassic, and Cretaceous periods and is known as the time of the dinosaurs. Cockroaches first appeared in the fossil record during the Permian period, following the Mesozoic era.
Where did cockroaches originally come from?
Cockroaches are ancient insects, believed to have originated over 300 million years ago during the Carboniferous Period. Fossil records suggest that the earliest known cockroach lived during the middle Carboniferous period.
This species, called Carbonimykia sectoria, resembled modern-day cockroaches and was about 1 cm (0.4 inches) in length. Cockroach species evolved over time and migrated all over the world. Today, there are over 4,000 species of cockroaches, the majority of which can be found in tropical and subtropical climates.
It is unclear how cockroaches first became established in human dwellings, though they may have been drawn to warmth, food, and shelter.
How did roaches get to America?
Cockroaches, or roaches, are believed to have first arrived in America on ships with the earliest explorers, settlers and traders. As cockroaches can survive for weeks without food and some can survive for months without water, it is thought that these critters came from all over the world.
They may have been floating in between wooden beams, cargo, or living in the walls of ships, where they could hide and feed on food, spilled water and other resources.
Cockroaches can lay their eggs inside tiny crevices, thus making it easy to bring them to foreign land. And as those eggs hatch, the next generation of roaches can spread the species much quicker. By the time the ships arrived on American shores, they may have already been infested with roaches that had enough time to reproduce.
In recent years, it has been suggested that global trade such as the import and export of items including furniture, clothes and food may have also transported cockroaches to different parts of the world.
What happened to insects after the asteroid?
The asteroid that hit the Earth 66 million years ago had a devastating effect on the planet and its inhabitants. While the impact is well-known for its role in wiping out the dinosaurs, the effects on insects were equally catastrophic.
Immediately after the asteroid impact, the Earth’s environment underwent drastic changes. Temperatures dropped drastically, creating an inhospitable environment for most animals, including insects. It is believed that many species of insects died out, while those that survived were forced to adapt to the new conditions.
In the millennia that followed, insect populations recovered in some areas, but their diversity was much lower than before. Insects had to evolve and adapt to the new environment in order to survive.
This included the development of new behaviors and physiological features that allowed them to survive the colder temperatures and lack of food sources. Over time, these changes caused species of insects to evolve in different directions—some became larger, others became smaller, some developed new defensive mechanisms, and others specialized to live in a specific type of environment.
Today, insects are one of the most diverse groups of organisms on the planet, having adapted to almost every type of environment on Earth. They are living reminders of the catastrophic effects of the asteroid, and how life can rebound and continue to thrive even after major disturbances.
