Dinosaurs

The first dinosaur fossil ever found in Antarctica is called Antarctopelta. Its fossils date to the late Cretaceous period. Cryolophosaurus, the first theropod discovered in Antarctica, date back to the early Jurassic period.

An asteroid impact in the Caribbean just off the coast near what is now the town of Chicxulub Mexico caused an explosion of 15,000,000 times of the 50 Megaton nuclear bomb or 'Tsar Bomba' which removed the dinosaurs, the few who survived died of lack of oxygen due to the CO2 it released aftermath of the explosion. The tsunami resulting from this impact swept as far inland as the northern part of what is now the state of Texas!

Crylophosaurus lived in the Jurassic Period.

Most dinosaurs lived in the Cretatious and the Jurassic periods

Icthyosaurus died out around 93 million years ago. The cause of their extinction is unknown, but could have been climate change or, less likely, competition from plesiosaurs and mosasaurs.

The african dinos like ouranosaurs and carcharodontosaurus, may probably lived in the savannas.

yes

To stay alive, larger animals need more food than smaller animals. But it also matters whether an animal is warm-blooded or cold-blooded. Since we aren't sure about dinosaurs, figuring out how much food they ate is not quite so simple.

Warm-blooded animals have a higher metabolism: they need more food to stay alive. Cold-blooded animals have a lower metabolism: they need less food to stay alive.

becasue he took his school notes on a rock. and ate leaves with the dinosaurs.

It is not known what kind of eyes dinosaurs had. They are often depicted with silt pupils simply for dramatic purposes.

Carnivores

the best time of dinosaurs was the jurassic period where big sauropods ruled the earth ,late in the cretaceous period some species of dinosaurs were in decline before the hit of the meteorite that killed all dinosaurs

no. they died because of a meteor or something.

--------------------------------------------

May be one of the causes. But I've heard about the incessant falling of meteors on the earth and the meteorites which are so large in size just plunged the creatures in to the earth.

Sir Richard Owen coined the term "dinosaur" in 1842. The name means "terrible lizard" because they were reptiles, and many of them were huge.

Dinosaur are not mammals. Mammals and dinosaurs evolved from completely different genetic lines. Birds are the closest and only living decedents of dinosaurs (except possibly a few rare species not known to science and only known to local tribal legend such as Mokele-Mbembe but this is not widely believed)

Adult Giganotosaurus would not have had any threats except other Giganotosaurus. However, a young, unprotected Giganotosaurus would have been attacked by any carnivore larger than it, including Ekrixinatosaurus, Bicentenaria, and crocodile-like animals.

carnivore

they sound all grally like a tiger or a lion

The largest dinosaur is Amphicoelias, at 200 ft long.

The age of the dinosaurs was called to the Mesozoic Era, divided into three periods; Triassic (250-144 million years ago), Jurassic (144-90 million years ago) and the Cretaceous (90-65 million years ago). Keep in mind that dinosaurs, even the earliest ones, didn't pop up until roughly 230 million years ago.

No. They're all dead.

When they were alive, the carnivores certainly did bite. Their jaws were filled with razor-sharp teeth specifically for biting, killing and eating.

Dinosaur lived in pretty much anywhere in the world some migrated to other parts of the world

The simple answer is yes. The complicated answer goes a little more in depth. Monsterquest on the history channel recently did an episode which followed bill gibbons to the remote countryside of cameroon where many local villagers claim to have encounters with the creature they call moleke-mbembe. They describe the beast as having a long neck, a snake-like head, a massive body and spines running down its back and tail. They accurately draw pictures in the dirt with sticks depicting a sauropod dinosaur. Western scientist will have us believe that dinosaurs died out 65 million years ago and the chances for a breeding colony of any species of dinosaur is nonexistent. However, if we rely upon the eyewitness testimony of those who claim to see the creature we will find that science has not discovered every living species on the planet. A further point of fact to consider is the spines described by the eyewitnesses. Western science has only recently discovered through examination of fossilized skin of a Sauropod (diplodocid) that a median row of spines was present over the tail and may have continued anteriorly along the body and neck. In light of this evidence, we now must give considerably more weight to the testimonies of the local villagers in Cameroon who claim to have seen a sauropod dinosaur with spines running along the back and continuing to the end of the tail. After all, how could villagers with no formal education, with a complete lack of western contact, know that some sauropod dinosaurs had spines without firsthand knowledge of the creatures. Only by blindly accepting current ideas that all the dinosaurs died out millions of years ago will we find ourselves saying that, "No, moleke-mbembe is not a dinosaur and no dinosaurs have ever lived on the earth at the same time as man."
