the same amount of water we have today... (70%)
Many dinosaurs ate meat. Some are Allosaurus and Tyrannosaurus rex. No dinosaurs lived in water
there were no types of water dinosaurs. Diosaurs only lived on land.
No dinosaurs lived in water. The prehistoric reptiles that lived in water were the Plesiosaurs, not dinosaurs.
No dinosaurs specifically lived in the water. Plesiosaurs, pliosaurs, mosasaurs and ichthyosaurs lived in the water (but are not DINOSAURS). They are reptiles but not dinosaurs. They co-inhabited the planet with dinosaurs, in the same way that the pterosaurs ruled the air. Pterosaurs were not dinosaurs either.
very swanmpish and a lot of plants and rocks in it
dinosaurs actually lived every where we live on. Millions of years of go Dino's lived here .The Dino's also bathed in the water we drink and we bath in but today we have filters that clean the water.
The Water When The Dinosaurs Lived Is The Same As The Water We Drink today.But We Make Changes To The Water,Even If We Do It Will Be The Same Water As The Dinosaurs Drank(Get It?)
Dinosaurs were all reptiles and therefore, land dwellers. None of them could breathe underwater, although marine creatures that lived along side the dinosaurs have similarities to the dinosaurs, they weren't actually classed as dinosaurs. Therefore, no dinosaurs could breathe under the water :) EDIT Fish and some amphibians are the only vertebrates that have gills and can breath underwater. The same applies to ancient animals too.
According to most scientists, we have had virtually the same amount of water on Earth since the planet formed. That would mean that there was the same amount of water on Earth when the dinosaurs existed. However, it is important to note that there is probably an infinitesimal amount more water now then there was in the time of the dinosaurs, simply because of the fact that there have been meteors/meteorites that carried a little bit of water to Earth since the dinosaurs died out.
First of all, the true definition of a dinosaur is a terrestrial vertebrate reptile. This means that they all lived on land. None of them flew (but some were able to glide and evolve into birds) and none of them lived in the sea, but could have swam short distances. The correct term for the animals who lived in the seas during the time of the dinosaurs is "Sea Reptiles." These are split into two main groups; the icthyosaurs, which are more fish- like and adept to the water, and the plesiosaurs and pliosaurs, which more represent the sauropod and theropod dinosaurs with which they lived alongside.
You used past tense on the word lived. How do you know they all died? They lived on earth with humans, because God created everything in 6 days, so dinosuars are a part of everything, right? So Adam and Eve HAD to have seen dinosaurs, right? Creationists have found footprints of human and dinosaur feet walking next to each other so dinosaurs lived with humans. Have you ever heard of the Loch Ness Monster? It's description describes a body of a water dinosaur, so the Loch Ness Monster could very well be a dinosaur that never went away. All dinosaurs haven't gone extinct!
we can't say, because were discovering more all the time. there is actually no such thing as a dinosaur that spent its whole life in water as one of the definitions of a dinosaur is an animal with steady legs that support it on land. any water animal would have flippers so they cant stand. the animals that lived in the water were just animals that lived in the dinosaur period not actual dinosaurs.
