What is a list of dinosaurs in Jurassic Period?
There was the T-Rex, the dragon, the eragon (Like in the movie), the stuff from world war 2 and the poo man.
Information about Allisaurus Dinosaurs?
He was he largest carnivore in north America during the jurasiac period. See the related link for more information.
What animal today causes the most animals to go extinct or to be in danger of going extinct?
Humans are the answer! humans caused more animals to go extinct than any other animal.
An omniraptor is a futuristic dinosaur related to velacoraptors from the past
When did the last living dinosaur die and what species was it?
Well, Dinosaurs descend from the reptile family, as do snakes, turtles, lizards, crocodiles and komodo.
So these are animals related to the dinosaurs and all are living species.
[An important feature to note is that those which survived the effects of the meteor impact in Mexico, (65 million years ago, and known to the geologists as the K/T boundary) all lived underground or in the water. Top predators such as sharks must have had a good day. ]
The closest to the dinosaur family today is the Tuatara of New Zealand, of which two species still exist. These are often referred to as living fossils of the dino family, but in the 200 million years, the Tuatara itself will also have evolved.
They are known as Sphenodontia, and the dontia bit refers to the small tooth on the end of their beak which they use to cut through their shell.

What is the Name of the fast moving dinosaur?
The Gallimimus was a 4 meters long and could reach speeds of 65 km/h. About as fast as a modern racehorse.
Is the deinosuchus still living today?
It is still living today but a smaller version of it. It is the alligator.
Daspletosaurus was a carnivore and usually preyed on Maisaura and Einiosaurus.
Are all of the dinosaurs gigantic animals?
No, that is not true. Although dinosaurs were very large, the blue whale is much, much bigger. It's heart weighs about the same as an average car! These huge underwater mammals are known as gentle giants.
What do carnavil dinosaurs eat?
If you're asking what carnivores eat they eat meat. Like other dinosaurs.
If you mean paleontologists, they are people who study/dig up prehistoric animals.
(Dinosaur bones.)
I think reptiles are no longer classified under their own taxon, therefore they have to be distinguished between avian and non-avian to be able to get the technical wording correct
How have scientists proven that dinosaurs were actually real?
The existence of their fossilized bones, together with the geologic strata in which they are found and the relationships of the bones of single and multiple individuals are proof the dinosaurs existed. Limited DNA testing has shown their relationship to species now living.
What creatures lived next to dinosaur that could breath under water?
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.
If dinosaurs died then how can humans be alive after the dinosaurs went extinct?
Because dinosaurs and humans never met.
Dinosaurs died out 65 million years ago. Humans (Homo Sapiens) are only 200,000 years old.
How many dinosaur skeletons are there in the Royal Tyrell Mueseum?
The research facilities at the Royal Tyrrell Museum house over 125,000 fossil vertebrates and invertebrates. Unfortunately the viewing collections are not made public.
How the thermos flask prevents heat loss by radiation?
A thermos bottle prevents heat transfer to the outside by using a vacuum between the walls of the bottle.
The innerwall is usually made of glass while the outside wall is made of a plastic.
Metal walls also exist.
A vacuum doesnt conduct, since you need a substance to conduct heat.
Same goes for convection, warm and cold liquids / gasses can rise and drop all they want, but the heat cant be passed on to the outside wall.
Radiation is prevented by using reflective surfaces, which bounce back into the substance you are carrying in the bottle.
If you are wondering whether they had fur, they didn't. Many types of theropods had primitive feathers, however, and some small ceratopsians had feather like bristles on their backs. If you want to know whether they had fear, I think it is safe to say they did when they were in danger. All vertebrate animals have a fight or flight response which is felt by the animal as fear and/or aggression. It is caused by stress hormones, which give the body a boost for surviving a life threatening situation.
What did birds look like when dinosaurs ruled earth?
Birds looked like cockroaches when dinosaurs ruled the earth.
Dinosaurs were not always mean and those that were were not intentionally mean. Dinosaurs went on instinct so they did not choose what they did. Carnivores("meat eaters") were usually the ones pictured as the mean ones.
How do you know dinosaurs laid eggs?
Fossils, research. They have reproductive organs in the bones. No one really knows for sure.
