there were no types of water dinosaurs. Diosaurs only lived on land.
Many dinosaurs ate meat. Some are Allosaurus and Tyrannosaurus rex. No dinosaurs lived in water
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.
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.
very swanmpish and a lot of plants and rocks in it
the same amount of water we have today... (70%)
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?)
well florida was submerged under water so what was found was prehistoric sharks and sea urchins.
Dinosaurs never lived underwater. There were marine reptiles that are sometimes inaccurately called dinosaurs; these include icthyosaurs, mosasaurs, plesiosaurs, and pliosaurs. All of these are extinct. There are a few marine reptiles alive today, though. These are sea turtles, sea snakes, and the semi-aquatic marine iguana.
The scientist believe the dinosaurs did because of many reasons Some think that a meteor strike the earth and with all the dust that covered the atmosphere the sun light couldn't get in so the plants started to die and with them the plant eaters dinosaurs and with them the carnivores. Other scientists believe the the earth started to get very cold and because the dinosaurs didn't have fur or feathers to protect them self from such harsh temperatures they all eventually died and the dinosaurs that lived under water died because the water froze so the froze too.
mosasaur was a strict carnivor. there were accually no plant eating dinosaurs that lived in water.
