Trilobites existed between 521 and 250 million years ago. Currently, there are 17,000 known species, but there were probably many, many more that have not been discovered, although they didn't all live at the same time.

What is the pterodactyl evolution?
Pterodactylus was a pterosaur, and pterosaurs were archosaurs. All pterosaurs died out 65.5 million years ago. Other types of archosaurs include crocodillians, the dinosaurs, and the birds, which evolved from dinosaurs. The pterosaurs were more closely related to the dinosaurs than they were to crocodillians, so the closest living relatives of pterosaurs are the birds. All birds are equally related to pterosaurs.
Where is a pterosaurs habitat found?
There were hundreds or thousands of different species of pterosaurs, and different types lived in different places at different times. Thus, some types of pterosaurs would have existed in each type of habitat that existed at that time. Some environments would have included deserts, coastal floodplains, swamps, and somewhat dry woodlands.
What other modern day species are the pterodactyl's related to?
Pterodactylus was a pterosaur, and pterosaurs were archosaurs. All pterosaurs died out 65.5 million years ago. Other types of archosaurs include crocodillians, the dinosaurs, and the birds, which evolved from dinosaurs. The pterosaurs were more closely related to the dinosaurs than they were to crocodillians, so the closest living relatives of pterosaurs are the birds. All birds are equally related to pterosaurs.
When did the pterosaurs become extict?
Pterosaurs died out 65.5 million years ago during the K-T Extinction Event. The K-T Extinction Event not only wiped out the pterosaurs, but all non-avian dinosaurs, the plesiosaurs and mosasaurs, and many types of plants and animals that are not as well known today. In fact, it is believed that 75% of species went extinct.
How much pterosaurs weight?
There were many different types of pterosaurs. The largest known pterosaur was Quetzalcoatlus, and may have weighed as much as 500 pounds, although it is not certain that it was able to fly. The small pterosoaurs, however, probably weighed about the same amount as average birds do today.
Pterosaurs were flying mammals many of which were the size of todays predatory birds True or false?
False, pterosaurs were flying reptiles.
Good dino fact on pterosaurs?
Pterosaurs were carnovores. They ate fish. they were also predators not prey.FOR FEATURES WHEN THE PTEROSAURS LIVED The primitive types of pterosaurs appeared during the Triassic period , and died out at the end of the Jurassic period. More advanced pterosaurs appeared late in the Jurassic period and died out during the Cretaceous period. SIZE Their wingspam is 12metres long. The head is 1 metre long.The body is 3 metres long.
Does pterosaurs eat humans?
No. Pterosaurs are extinct and humans never met the dinosaurs/pterosaurs.
Do pterosaurs fly?
Yes, pterosaurs were flying creatures.
What are the pterosaur's prey?
There are over 135 different known genera of pterosaurs, and each species would have had different types of prey. Small pterosaurs like Pterodactylus probably ate insects, small land animals, and fish. Large pterosaurs such as Pteranodon probably ate fish, while other large pterosaurs like Quetzalcoatlus would have eaten small land animals, albeit larger than the prey of Pterodactylus.
Were there any hyper-carnivorous Pterosaurs?
All known pterosaurs were carnivores. There is no evidence that any pterosaurs ate any plants at all, and thus it is safe to say that at least most, if not all pterosaurs were hypercarnivorous.
How many years ago did Pterosaurs fly?
The pterosaurs flew during a time period staring about 220 million years ago and ending 65 million years ago.
