They had long tails, scales, and laid eggs

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 )
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.
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.
All reptiles share several key characteristics including having dry and scaly skin, being cold-blooded, laying shelled eggs, and having a backbone. Additionally, most reptiles have four legs with clawed toes or no legs at all.
All around us. Birds are direct descendants of dinosaurs and share many characteristics with their ancestors including feathers. As for the rest of the dinosaurs 99% of all species that have lived on this planet have died out or evolved into something else. There is no reason dinosaurs should be any different.
Humans and lizards share the same level of classification as vertebrates, belonging to the Phylum Chordata.

All reptiles are diapsids. Mammals (like you and I) are, in contrast, synapsids. So in that respect all reptiles are alike. However, I would not say they were all alike. Snakes are reptiles but lack limbs. Alligators are also reptiles, as are lizards. Tuatara, gavials, amphisbaenids, and tortoises each represent one of the four main modern orders of reptiles. They share some characteristics--just as you and I do, but I would not say they were all alike.
yes. scientists do not share it in public.
no, but they share a common reptile ancestor.
Yes. they share many characteristics.
