What else can I help you with?
do lizards descend directly from dinosaurs?
The prevailing opinion of evolutionary biologists is that lizards are not directly descended from dinosaurs but are related species which diverged from the dinosaurs hundreds of millions of years ago. However, dinosaurs do have direct living descendants, and those are the birds. Birds descend from dinosaurs.
Is the tuatara a dinosaur?
No. Tuataras are in the lepidosaur branch of reptiles, which they share with lizards and snakes. Dinosaurs are on the archosaur branch, which they share with crocodilians. Birds are the only living dinosaurs today.
Is Tuatara a dinosaur?
No. Tuataras are more closely related to lizards and snakes than to dinosaurs. Dinosaurs are more closely related to crocodiles and even more closely related to birds, which are their only living descendants.
How long have tuataras been on earth?
Tarantulas have been on Earth for at least tens of thousands of years, probably much longer. Their ancestor species have been on Earth since before the dinosaurs, hundreds of millions of years ago.
Was pterodactyl ancestor of birds?
No. Pterosaurs share a common ancestor with the dinosaurs, but are not classed as dinosaurs themselves. Birds, however, descend from a group of dinosaurs called theropods; the earliest bird know, Archaeopteryx, dates to about 150 million years ago. The theropods also include dinosaurs such as T. rex, velociraptors, and other bird-like dinosaurs.
Why have tuataras and platypuses outlived dinosaurs?
Luck - being in the right place at the right time. The modern platypus is nothing like old enough to have been around with the dinosaurs though - oldeset fossil - around 100,000 years - dinosaurs were here something like 230 million years ago.- ANSWER 2: The above is not strictly correct. Platypus fossils indicate that earlier platypuses were very similar to modern platypuses, only bigger, while tuataras have, of course, remained virtually unchanged since they walked with dinosaurs. It would seem that climatic conditions enabled these two creatures to continue to exist. Unlike the dinosaurs, they were not affected by changes further down the food chain. Further, their isolation from the rest of the world enabled them to thrive without the constant threat of predators.
