Dinosaurs

It has to do with the food chain. Say if T-Rex are extinct, the animals it eats over-populate and take all the food or water. Slowly, all the animals start to become extinct. Or, if a certain animal becomes extinct, the things it eats over-populate and the things that eat it normally become extinct.

Brontosaurus means "thunder lizard" in ancient Greek. Othniel Charles Marsh named it Brontosaurus because of its impressive size. However, Brontosaurus is actually an invalid name for Apatosaurus excelsius.

Dinosaurs are believed to have gone extinct approx. 66 million years ago

like the green giant :)

Stegosaurus are Rainbow Chromatic, sometimes it changes color depending on it's mood, other times it changes to what it feels like. They also change to camouflage to catch prey or hide form predators. They include colors such as Lime Green, Crimson Red, Fuchsia, Highlighter Yellow, Bright Blue, Dark Blue, and Electric Purple. Basically any Bright, Neon color. So, short answer to your question, Yes.

It would depend what kind of dinosaur. Small therapods like Microraptor and Compsognathus may of only had a short life span of only 3-4 years, whilst the giant sauropods such as Apatosaurus and Camarosaurus would have probably lived to maybe even 100! It all depends on the dinosaur's size. This isn't always true of course, if the animal caught a disease or was attacked it wouldn't live as long, obviously. This all just theory, but the most likely one.

what an interesting topic! Birds and reptiles are the living descendantsof the dinosaurs that survived the meteorite-triggered mass extinction that killed off most of the species living 66 million years ago. And of all reptiles, crocodiles are the most closely related to birds.

The largest sauropod species was Argentinosaurus, which averaed about 90 to 100 tons

No. Alligators are not descendants of dinosaurs, so you cannot make a dinosaur using an alligator. Birds, however, are living descendants of dinosaurs and still have some genes which have been essentially switched off. One scientist believes he can bring out more dinosaur-like traits by tampering with the DNA of a chicken.

No. In the Bambrian Era, dinosaurs had yet to evolve.

The brief and simple answer is that no one knows. The most likely explanation is that an oral traditions of monster were exaggerated by following generations until the stories were finally written down giving rise to different types of dragons in different parts of the world. If you would like a fun look at the science of dragons you can watch this video -

The Alamosaurus are part of the Titanosaurus family. It has a long neck and tail, also columnbular legs. It is approximately 69 ft long and 33 tons. It is a quadrupedal plant-eating dinosaur. It has flat and slender teeth meant for plants, not meat. The first findings was found in North America in states like New Mexico, Utah, and Texas. These huge dinosaurs was preyed on by tyrannosauruses and many more.

Dinosaurs existed from 230 to 65.5 million years ago. That was from the mid Triassic period to the end of the Cretaceous period. All three periods were in the Mesozoic era.

Humans came after Dinosaurs.

No.Dinosaurs did not have the right type of skin.

The taxonomic grade "Prosimii" (prosimians) is no longer considered phylogenetically valid, it's a paraphyletic grouping of primates that are "neither monkeys nor apes". However, it is entirely possible that early primates lived during the Cretaceous, the last epoch of the Mesozoic, when dinosaurs ruled the Earth. No fossils have been found (some questionable material belonging to an early plesiadapiform Purgatorius has been attributed as Cretaceous in origin, but it's possible that this material was accidentally re-buried in a Cretaceous stratum at a later date). The earliest definite primate known from the fossil record is Plesiadapis, which lived some 55 million years ago, 10 million years after the dinosaurs went extinct. However, molecular clock studies indicate that the primate order may have arisen 85 million years ago, during the Late Cretaceous. Certainly, primate ancestors were alive at this time, though whether they could be placed in the order Primates is still an open question. It is very likely that if you were to see one of these early primates/primate ancestors today, you would think it was some strange kind of shrew, rather than a primate as such, since they did not yet physically resemble the monkeys, apes or even lemurs of later epochs.

Axolotls are not dinosaurs. Axolotls belong to a group of animals that's older than dinosaurs.

There was no years 85 million years ago. Man made up the idea of years, dates, or time. The dinosaur existed 65 million years ago.

scientist found out about the bones and named them by what they look like.

There are many plant eating dinosaurs also known as herbivores but i will list a few for you

1. Stegosaurus the stegosaurus had protective plates around its body to help keep away predictors

2. diplodocus this herbivore had a very long tail to whip its predator but it also was very big

3. triceratops this one had three big horns on the top off his head

Tyrannosaurus had teeth up to 18 centimetres long. These teeth had a razor sharp point to stab prey ,and rough - saw like edges to rip through flesh. An adult had between 50 and 100 teeth and if one fell out, it simply grew another!

Dinosaurs which ate meat were the smartest ones, had claws, had sharp teeth and always walked on two legs* (for running fast to catch their prey). Some examples are: Tyrannosaurus Rex, Velociraptor, Allosaurus, Carnotaurus. There are alot more. *Some plant eaters walked on two legs too.

A sauropod is a dinosaur that walks on 4 legs and well......here is an example: diplodocus (look it up if u dont know it) and another is brachiosaurus.
