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."

What observations did scientists make about dinosaurs that made them think dinosuars were not lizards?
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 )
What do many dinosaurs and lizards have that are the same?
they had the same brain
Many claim that dinosaurs are closely associated with what?
Lizards, turtles, and Snails.
How are dinosaurs related to dragons?
Dinosaurs and lizards both belong to a branch of reptiles called diapsids, which emerged in th early Permian period. In the early Triassic period the diapsids split into two main groups: archosaurs and lepidosaurs. The archosaurs were the ancestors of dinosaurs, pterosaurs (flying reptiles), and crocodilians. The lepidosaurs were the ancestors of lizards, snakes and a third, nearly extinct branch called sphenodonts.
What characteristices do dinosaurs and today animals share?
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.
What the different between dinosaurs and birds?
Not a whole lot. Birds and dinosaurs share the same skeletal structure and walk the same and many had feathers and were probably warm blooded.
What is the Difference between a reptile and a lizard?
snakes: no legs, no visible ear, slow metabolism, sometimes constrict preylizards: legs, visible ear, faster metabolism, teeth, no fangsThere are no differences, a snake is a reptile. Reptile is the family and snake is the genus.
What is the Genus and species of lizards of lizards?
Lizards are not one single species or genus. There are many different species and genera of lizards, ranging from the tiny Pygmy Chameleon to the gigantic Crocodile Monitor. The taxonomic order which all lizards share is: Kingdom: Animalia Phylum: Chordata Class: Reptilia Order: Squamata Sub-Order: Lacertilia
Where are dinosaurs now?
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.
What observation did scientists make about dinosaurs not being lizards?
There have been a number of observations. First of all, although they are still considered reptilian, analysis of ancestor animals shows that dinosaurs were more closely related to crocodiles than to lizards. More importantly, however, dinosaurs have a number of characteristics not found in modern reptiles. While modern reptiles have their legs jutting out to the sides while dinosaurs walked with their legs vertically beneath them. Many dinosaurs, particularly the two-legged carnivores known as theropods, have skeletal features that are closer to those of birds than to those of reptiles. Finally, while evidence shows that some dinosaurs had scales, a growing number of dinosaurs are being found to have had feathers.
