They had long tails, scales, and laid eggs
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.
The simalarities that dinosaurs and reptiles share are they both lay eggs have rough skin.
Looking at their evolutionary history, the tuatara belongs to broad group of reptiles called lepidosaurs, which they share with lizards and snakes. Dinosaurs belong to a different group called archosaurs, which they share with crocodiles and alligators.
dinosaurs shared many features with todays lizards. they had skeletons with backbones. they had scales. many walked on four legs. but there differences between the two groups of animals. dinosaurs legs go almost straight down from their bodies. legs of todays lizards stick out more from the sides of the bodies. some dinosaurs share many features with birds. for instance, some dinosaurs had features and a wishbone! also, a few fossils have included more than just bones. these fossils have shown that some dinosaurs had a heart that is similar to a birds or a mammals heart. NOTE: ( i got this info from my science book )
Humans and lizards share the same level of classification as vertebrates, belonging to the Phylum Chordata.
no, but they share a common reptile ancestor.
yes. scientists do not share it in public.
Dinosaurs are more closely related to mammals. Both mammals and dinosaurs share a reptilian ancestor that they don't share with amphibians.
They were both reptiles, meaning that they could lay eggs out of the water. Many of them probably had scales, as do snakes and turtles. In terms of locomotion, body chemistry and care for their young, however, dinosaurs were much more like today's birds. In fact, some scientists consider them so close that those creatures like T. rex are referred to by the modifier "non-avian dinosaurs."
Well you can't really because dinosaurs are extinct.
The theropod dinosaurs share some similarities with birds, including a somewhat similar posture and possibly the same air sac based repository system. Many theropods also had feathers.
