they all have hearts and brains. they also have guts and bones. thank you for asking a stupid question
Dinosaurs
Yes, all animals we have now lived then, just some that lived then have gone extinct so we don't have them now.
No! Although this is a common mistake, all dinosaurs were land animals. All animals that lived in the sea at the same time as the dinosaurs weren't actually classed as dinosaurs even though they have similarities :)
The occupation of the dinosaurs was pretty much the same as all animals: eat, sleep, reproduce.
Not only that dinosaurs are directly descended from reptiles and, under current taxonomy, are classified as reptiles.
If the Big Bang didn't hit earth many animals such as dinosaurs would still be living now!
Dinosaurs were land dwellers, though some probably could swim it was not their main form of locomotion. However in the time of the dinosaurs there were also two classes of marine reptile that are now extinct. There where Icthyosaurs, which resembled dolphins, and Plesiosaurs, which had paddles for limbs, but these were separate from dinosaurs. As to flying, there were also flying reptiles during that time called pterosaurs. Again these were a group of animals separate from, but related to dinosaurs. However, one group of flying animals than many scientists now consider to be a branch of dinosaurs are the birds.
In a rudimentary manner much the same as lower animals do today.
2 animals that are related to dinosaurs are sharks and croodiles.
Sharks are Sharks and dinosaurs are dinosaurs. But there were animals recognizable as Sharks living when the dinosaurs did.
Animals of the Ice Age lived after the dinosaurs.
No not all fossils animals are dinosaurs. They still are snail fossils and other fossils.
