Alligators and Crocodiles lived in prehistoric times, however are not considered proper dinosaurs. Most prehistoric creatures were made extinct many years ago.
..During that time, some scientists believe Ohio was at least partially underwater, because many Trilobites were found there. Some also believe that erosin destroyed most of the remains. Edmontonia remains have been found though, and those are pretty sweet.
yes, the pear has been around for many years.
Fossils are the remains of dinosaurs, prehistoric plants and other prehistoric creatures which lived millions of years ago. Artifacts are items that were made by intelligent homonids or by ourselves (homo sapiens) in the past not so long ago.
Prehistory is used to describe the time before history was recorded. The Stone Age began 2. 5 million years ago and is usually described as Prehistoric, because no history was recorded on walls, writing, or pottery.
I'm not sure what you mean by prehistoric mammal. Prehistoric usually means 'before recorded history' which means before writing. Writing has only been around for about 5000 years, which is much less than the time mammals have been around. They first appeared more than 200 million years ago. Even fairly late developments like the emergence of modern humans from earlier hominids happened around 200 000 years ago. So really all mammals are prehistoric.
since the prehistoric ages about 95 million years ago
Scientists believe that trilobites reproduced sexually. These prehistoric and extinct creatures were a type of arthropod that probably laid eggs. Trilobites lived about 250 million years ago.
There is no record stating that prehistoric alligators had three eyes. It is believed that they had two eyes, just like they do now. Alligators have likely been around for 150 million years.
Prehistoric refers to anything which preceded written accounts.Anything before the invention of writing (around 5000 years ago) is considered prehistoric.Before recorded history. Such as dinosaurs, fosils, the formation of the continents are all prehistoric.
