to dinosaurs. to is the preposition and dinosaurs is the object of the preposition.
Yes. In fact birds are direct descendants of dinosaurs, and many consider them to be dinosaurs. Crocodiles are also related to dinosaurs.
Alligators and Crocodiles lived in prehistoric times, however are not considered proper dinosaurs. Most prehistoric creatures were made extinct many years ago.
Yes. They were all reptiles.-------------------------------------------------------------------------------------------------------Specifically, both the crocodilians and the dinosaurs are archosaurs ("ruling reptiles"), members of the clade Archosauria, which also includes the pterosaurs and many other related animals which are now extinct.
Not like Jurassic park style, However many paleontologists classify birds as dinosaurs. Crocodiles and alligators are also dinosaur relatives though they are not dinosaurs.
No crocodiles are NOT dinosaurs. Dinosaurs and crocodiles are however both archosaurian reptiles. Crocodiles are somtimes refered to as ''living dinosaurs''. This is based on the idea that their anatomy hasn't changed much over millions of years. It does not mean that they are members of the group dinosauria. Modern day birds on the other hand ARE dinosaurs.
Crocodiles and other members of the group crocodilia are the dinosaurs closest living relatives.Crocodiles are somtimes refered to as ''living dinosaurs'', this is based on the idea that their anatomy hasn't changed much over millions of years. Crocodiles are not however dinosaurs themselves.Modern day Birds on the other hand ARE dinosaurs.Birds are a type of maniraptorian theropod dinosaur. Birds are the only dinosaur group to survive the mass extinction ~65million years ago. So therefore dinosaurs are Not extinct. (and they are doing quite well. There are approximately twice as many birds species than there are mammals.)Birds are therefore Crocodiles closest living relatives. And vise versa.Crocodiles and dinosaurs (+birds) are both members of the group Archosauria.Yes, both dinosaurs and crocodilians are archosaurs (the "ruling reptiles", they belong to the clade Archosauria, along with pterosaurs and some other closely related, but extinct, animals) and are therefore fairly closely related. Crocodiles however are NOT dinosaurs, nor did they evolve from dinosaurs (or vice versa) - they are simply related to them.
The Mesozoic era is divided into three periods Triassic, Jurassic and Cretaceous. During the early Triassic, corals appeared. Seed plants dominated the land, in the northern hemisphere, conifers flourished. Glossopteris was the dominant southern hemisphere tree during the Triassic period. Many new dinosaurs appeared during the Jurassic period. Giant plant eating dinosaurs dominated the Earth. carnivores such as Allosaurus and Composognathus were plentiful. Many bird-like dinosaurs also thrived during this period. The Cretaceous period saw the heyday of the dinosaurs. Many new species of dinosaurs evolved during this period. New dinosaurs such as, the deadly t-rex and the extremely large Giganotosaurus appeared for the first time as did Triceratops and many others.
100 types of dinosaurs lived during the mesozoic era.
Probably not dinosaurs, since they were unknown during the "dragon-creation" period. Actually, dragons can resemble a great many animals, real and fanciful, inculding camels, harpy eagles, hippotamuses, serpents, toads (!) and carp. Mostly, though, dragons are creatures of the imagination.
Yes. Dinosaurs are a group of archosaurian reptile. (Other archosaurs include crocodiles and possibly the pterosaurs.) When people think of the word reptile they think of cold blooded sprawling creatures like lizards and crocodiles. Many are, but it's generally thought that dinosaurs were more probably warm blooded reptiles. Birds are also a type of theropod dinosaur so technically they to are also reptiles. Birds are warm blooded.
Approximately 700 Species have been named. Alligators and Crocodiles ARE NOT dinosaurs! However, Birds are largely considered to be the ancestors of saurischian dinosaurs and therefore could be said to be dinosaurs.
