No. By the time the dinosaurs went extinct mammals still played a relatively minor role ecologically. It is generally accepted that an asteroid or comet struck the earth, causing ecosystems to collapse worldwide and resulting the extinction of many groups of animals including the dinosaurs.
What else can I help you with?
Which two forms of life existed together on the earth during the same time period?
Dinosaurs and early mammals coexisted during the Mesozoic Era, specifically in the Late Jurassic to the end of the Cretaceous period. While dinosaurs dominated the land, early mammals were small, nocturnal creatures that adapted to life in their shadows. This coexistence lasted until the mass extinction event approximately 66 million years ago, which led to the extinction of the dinosaurs and allowed mammals to diversify and thrive.
Is it possible the asteroid that destroyed the dinosaurs has any connection with the existence of humans?
An asteroid did NOT destroy the dinosaurs. A flood did. Read the Bible. :) The flood was the one who killed the dinosaurs, but Noah took small dinosaurs (e.g lizards, crocodiles).
What were five living things from the Triassic period?
During the Triassic period, which lasted from about 252 to 201 million years ago, five notable living things included the early dinosaurs, such as Eoraptor, the marine reptile Nothosaurus, the archosaur Pseudosuchia, the plant Lepidopteris, and the first mammals, like Morganucodon. This period marked significant evolutionary developments, including the rise of dinosaurs and the diversification of early reptiles and mammals. The Triassic ecosystems were characterized by a mix of terrestrial and marine life, reflecting the aftermath of the Permian-Triassic extinction event.
What are mammals in mesozoic era?
Most mammals were much smaller than the dinosaurs and they were therefore better able to adapt to the conditions that brought the dinosaurs down. For example, a large dinosaur that ate vegetation would have died very soon if most vegetation was wiped out in a catastrophic event. Small mammals could still dig and forgage and make do with roots. It must have been horrific for everything alive at that time, but the very small creatures had the edge.
What are the dominant organisms or the tertiary period?
During the Tertiary Period the dominant organisms were mammals. These mammals included the many different types of dinosaurs that were roaming the earth 65 million years ago. Other organisms included bony fish such as bass and trout, flowering plants, insects, and birds.

Which two forms of life existed together on the earth during the same period?
Dinosaurs and early mammals coexisted on Earth during the Mesozoic Era. This era lasted from about 252 million years ago to 66 million years ago, with mammals evolving alongside dinosaurs until the mass extinction event that wiped out the dinosaurs.
During which era did mammals become common?
Mammals became the dominant land animals in the early Paleocene period of the Cenozoic era, after the extinction of the non-avian dinosaurs at the end of the Cretaceous period of the Mesozoic era.
Why weren't dinosaurs and cavemen together?
There was a mass extinction, killing of the dinosaurs before early hominids (humans) came along.
If humans evolved from the sea where did the dinosaurs evolve from?
Humans evolved from mammals like dinosaurs such as dimetrodon. All Vertebrate's evolved from the sea, Dinosaurs and Humans alike (the first were neither Reptiles nor Mammals but Tetrapods). These Tetrapods were the first to make the move from ocean to land: At the time of the Dinosaurs the only Mammals were tiny mouse like creatures unable to increase in size and complexity due to the domination of the Dinosaurs - that small size helped the early mammals to survive underground whilst the Dinos perished during the extinction event. And the rest, is history!
Did mammals appear in the fossil record after dinosaurs became extinct?
No, mammals lived alongside dinosaurs and their earliest known fossils of about 200 million years old are almost contemporary with the early dinosaur fossils.
Is it possible the asteroid that destroyed the dinosaurs has any connection with the existence of humans?
An asteroid did NOT destroy the dinosaurs. A flood did. Read the Bible. :) The flood was the one who killed the dinosaurs, but Noah took small dinosaurs (e.g lizards, crocodiles).
What type of animals were seen in Prehistoric art work?
Dinosaurs and early Mammals were seen in early artwork. Prehistoric birds were featured too.
Did the dinosaurs truly die out 65 millions of years?
All scientific evidence points to the fact that dinosaurs died out 65.5 million years ago, with the exception of birds. Birds evolved from dinosaurs in the late Jurassic to the early Cretaceous, and thus are considered a type of dinosaur. Of course, birds survived the K-T extinction and thrive today (there are more species of birds known than mammals).
When did the first dinosaurs and mammals evolve?
The first dinosaurs AND the first mammals both appeared in the Triassic period From the Mesozoic era.

What are each of the eras known for please answer?
Precambrian Era: Formation of Earth, origin of life, and evolution of simple organisms. Paleozoic Era: Explosion of complex life forms, including fishes, plants, and early amphibians. Mesozoic Era: Age of dinosaurs, rise of mammals and birds, and eventual extinction of dinosaurs. Cenozoic Era: Dominance of mammals, diversification of primates, and evolution of humans.
