the first dinos appeared 230mya during the late triassic period so it was well before the dinos time : )
dinosaurs lived for about 250 million years ago.
About 250 million years
the dinosaurs lived from 250 million years ago to 65 million years ago.
Archosaurs are not a branch of dinosaurs, they are a group of reptiles that include dinosaurs and a few related groups. Archosaurs first appeared about 250 million years ago (about 20 million years before the first dinosaurs) and continue to this day as birds and crocodilians.
yes the first dinos appeared 230mya during the late triassic period
Mouse-like mammals date back to the Mesozoic Era, 250 million years ago to about 65 million years ago, before the destruction of the dinosaurs.
I think they lived (the dinosaurs) for approximately 165 million years.
No. Dinosaurs first emerged about 230 million years ago and, with the exception of birds, went extinct about 65 million years ago. The first human-like creatures appeared about 5 million years ago.
From the fossils of the earliest dinosaurs, scientists have deduced that dinosaurs first appeared on Earth around 250-270 million years ago.
About 250 million years, from 300m to 65m, spanning three periods(Triassic, Jurassic, and Cretaceous
The first dinosaurs appeared on earth about 250 million years ago just after the Permian-Triassic mass extinction. The Triassic dinosaurs weren't too fierce and they were mainly neutrally defensive, which means they don't attack unless provoked.
Answer:The age of the oldest dinosaur fossils is some 250 mllion years ago based on radioactive dating. The age of the oldest human fossils is about 400,000 years, going back to 4 million years if you include proto-humans like Lucy. Dinosaurs had their day and died out some 70 million years ago, so there was no opportunity for Flintstone like interactions between the two species.AnswerNo, because the first dinosaur was 230 mya, and the first people were in the last 5 million years of prehistory. Do the math.
