The "-saur" part does refer to lizards, but the creatures were rather misnamed. In most respects, they were not very lizard-like, but hard more in common with birds.
There was an effort a few years back to refer to them as "Archisaurs," a category meant to include birds and crocodiles and EXCLUDE skinks and iguanas and varanids, but I haven't heard much of it lately.
Most obvious difference: lizard legs sprawl out to the sides, like turtle legs; dinosaur legs are directly under the body weight like birds, elephants, dogs and people.

''Sauria'' is a Greek word that means, as noted above, ''lizard''. When dinosaur fossils were first discovered, biologist Richard Owen coined the term Dinosaur, meaning terrible lizard. He knew that the fossils were not those of mammals and that they resembled reptiles more closely than anything else, hence the name.
The term ''Archosauria'' applies to a bona fide Clade and is still in use today. It refers to a group of diapsid amniotes whose living representatives are the birds and crocodilians. It also includes many extinct reptiles such as pterosaurs, some long-gone relatives of crocodilians, and the non-avian dinosaurs.
No. Lizards are not dinosaurs at all. Crocodiles and alligators are more closely related to dinosaurs than lizards are. Research from the past few decades actually shows dinosaurs were more like birds than modern reptiles. So in fact the only dinosaurs around today are not lizards or crocodiles, but birds.
There reptilians, dinosaurs are Archosauria.
Lizards are still around. The dinosaurs are extinct. Advantage lizards.
Why dinosaurs were so big is because in prehistoric times there was no winter. and dinosaurs are lizards and lizards never stop growing. so mixed with humidity and surplus of food the dinosaurs or lizards lived for hundreds of years and grow all that time.
The answer to you question both Yes and No ... Dinosaurs are the evolutionary ancestors of both lizards and birds but they, themselves were neither lizards or birds. They were a separate, distinct breed of beast. all to themselves
No. Frilled lizards are not dinosaurs, nor is any kind of lizard.
Yes. Dinosaurs are lizards because the only kind of animals on earth with scales are lizards and dinosaurs have scales.
yes because dinosaurs are gigantic lizards and lizards are still living in the world
Dinosaurs the Terrible Lizards - 1970 was released on: USA: 1970
yes because dinosaurs are big
giant lizards
Bearded dragons are lizards, and, like dinosaurs, lizards are reptiles. However, no lizards, including bearded dragons, evolved from dinosaurs. Birds, on the other hand, evolved from small, feathered, insectivorous or meat eating dinosaurs that lived in trees.
No, dinosaurs are not lizards.
No, birds didn't evolve from lizards, but they did evolve from dinosaurs, a different group of reptiles. Dinosaurs are different from lizards especially because of their hip structure. Birds descended from a group of dinosaurs known as theropods (bipedal carnivores)
