Dinosaurs

Some people think that dinosaurs were wiped out when a meteor hit the earth some people think that volcanos wiped out the dinosaurs

Presumably it was 140,007,988 B.C., but such precision is deceptive. Years beyond about 7,000 years ago are just estimates.

Funny story, though: A guard in a museum was asked how old a certain dinosaur was, and the guard said, "65 million and sixteen years." Asked how he knew the age so exactly, the guard said, "It came here sixteen years ago and it was 65 million years old then."

they ate fish.

No. By millions of years.

The earliest hominid (pre human) Homo habilis lived from about 2.4 to 1.4 million years before the present date. The end of the Age of Dinosaurs ended around 65.5 million years ago

A Doyathinkhesaurus Extinct

No they do not.

However they do have a fantastic dinosaur range based very accuratly on Jurassic park. check them out at papo's website.

Dinosaurs - about 150 million years. Humans - about 1 million years.

there are three reasons first the wind the rain the magma and the erosions

why people blurt stuff

Osteoderms are bony deposits forming scales, plates or other structures in the dermal layers of the skin. Osteoderms are found in many groups of extant and extinct reptiles, including lizards, and various groups of dinosaurs. Osteoderms are uncommon in mammals but do occur in most armadillos and ground sloths. In many cases osteoderms may function as defensive armor.

Plants evolved before dinosaurs, and dinosaurs depended on plants for food. The closest there came to "no plants" during the time of the dinosaurs was the mass extinction at the end, when plants died but left seeds behind that germinated when the dust thrown into the atmosphere by an asteroid impact settled and sunlight reached the surface. During that period of months or a few years without live plants, dinosaurs starved and died out.

Nations can coexist in peace if they agree to resolve their problems through compromise.

There are many different dinosaur orders all belonging to the superorder Dinosauria.

cat.

Well, usually they just do it cause they love you its called tough love

Hadrosaurs

When the asteroid hit, it launched a huge amount of dirt and dust into the air. This blocked out the sun over a large area, and that caused the Earth to become colder. The colder weather caused many plants to die. Without the plants to eat, many of the animals that ate the plants began to die, and then the animals that ate those animals, and so on down the line. Essentially the food chain collapsed from the bottom up.

Studying animals that are extinct can give us lots of useful and interesting information! Paleontologists (scientists who study life that existed in prehistoric times) attempt to determine when and why they died.They also try to learn about the creature's physiology, lifestyle, and if it is an ancestor of any of the living things present today. This can tell us about what the earth was like and what types of creatures roamed the earth when our fossil was still alive. Archaeopteryx is important because it is believed to be the first bird on earth! It is also evidence that birds have evolved from dinosaurs (there are some who disagree with this though). If you are interested in learning more about archaeopteryx I found a couple of websites you might like to take a look at:

There is no animal called the sitta osaurus. There is however, a stegosaurus. A stegosaurus was a herbivore that lived during the Jurassic and Cretaceous periods.
