Dinosaurs

Probably Spinosaurus

The Devonian time period ended because of a mass extinction of several species of fish, amphibians and other types of reptiles.

Dinosaurs existed 65.5 million years ago. Back then, a day was about 23 hours. Saying that an average day between modern times and the dinosaur age was 23.5 hours, and a year is 365.25 x 24 hours, then the dinosaurs died out about 24,431,500,000 days ago.

There were thousands of species, with between 500 and 1000 non-avian species catalogued from their fossils. There were many hundreds of co-existing prehistoric birds and marine dinosaurs.

There are lists at the related links.

Meat (Plant-Eaters).

No, they were reptiles.
There were not any dinosars that were mamals.Scientists in many museums have checked fossils, bones, and many other parts to tell.There are many dino eggs that have been found all over the world. Dinosaur means terrifying lizard in latin.

Brontosaurus (BRON-TOWE-SAY-RUSS), Pterodactyl (TEER-OWE-DAK-TILE), Tyrannosaurus Rex (TEE-RON-OWE-SAY-RUSS REX), Stegosaurus (STEEG-OWE-SAY-RUSS) and Triceratops (TREE-SEER-OWE-TOPS).

well there isn't a name for every phobia..... of course there are names for common phobias like arachnophobia, agoraphobia, acrophobia, etc. But if your phobia is as specific as this, its just called "specific phobia".

hey, we should start a club, i have phobia of dinosours too....... i cant even go to cinemas now... im too scared to find any posters with dinosours in it...... i hate those movies with dinosours.... not only Jurassic park.... i also hate travel to the center of the earth, etc.

Albertosaurus. Let's face it, Albertosaurus.

A paleontologist is a scientist who studies fossils to learn about prehistoric plants and animals.

Dinosaurs are not extinct. It is a right wing conspiracy designed to keep the public from fearing them while going about its daily activities. If the general public was aware that dinosaurs exist within the modern world, GDP would plummet since people would be afraid to go to work or even to the store to buy food. Thus, all dinosaur related deaths are quickly hidden from view and the family members paid off to keep quiet. I only know this because I am one of those family members who was paid to keep quiet; but I've decided to break the silence and I don't care what happens to me.

Rest in Peace, Father. Rest in Peace.

You don't have to "believe" in dinosaurs. There is evidence of their existence in the fossil record, unlike god. You can believe in god and deny that dinosaurs existed by citing the Genesis story in the bible, but the evidence for their existence is compelling. You can believe in god and in dinosaurs if you accept that the Genesis story is metaphorical rather than literal history.

They dominated the Earth for over 160 million years, from the late Triassic period (about 230 million years ago) until the end of the Cretaceous period (65 million years ago).

Animals that walk on two legs are called bipedal animals. The most obvious example of this is the human species.

It would be impossible to list them all here. Commonly cited are the pterosaurs such as the following:

Pteranodon

Pterodactyl

Petinosaurus

Quetzalcoatlus

Rhamporphydon

Archaeopteryx

Avisaurus

Piksi

Confiucionornis

Haopterus

Microraptor

Rahonavis

The Pterosaur

Rhamphorhynchus

pteranodon and quetzalcoatlus can fly

But these technically were not dinosaurs.

However, paleontologists not classify birds as dinosaurs. There are 10,000 known species of bird alive today and even more that are extinct. It would be impossible to list them here.

The Cretaceous period ended as the result of a mass extinction event, probably resulting from an asteroid impact. This wiped out 65 percent of life on earth, including the ammonites, the plesiosaurs, the pterosaurs, and, most famously, the dinosaurs.

A meteorite from space that blocked out the sun and made acid rain which poisoned all the plants so herbivores died out, with no food supplies for carnivores they all died out.

Good bye Tyrannosaurus Rex.:(

Acrocanthosaurus had spines as high as two feet (0.6 m) tall on its neck, back, and tail. The spines on its back were probably set in a ridge of flesh. These spines were not raised in a bony sail as in some later meat-eaters, such as Spinosaurus. Acrocanthosaurus had qualities in common with the earlier giant allosaurs of the Jurassic Period in North America. It also resembles giant meat-eaters that lived in South America nearly 50 million years later, such as Gigonotosaurus and Caraharodontosaurus. Since Acrocanthosaurus lived in lands between the habitats of allosaurs and later giant meat-eaters before and after time. It is the largest eat-eater known from the southern United States. A nearly complete skeleton of Acrocanthosaurus, was recently purchased by the North Carolina Museum of Natural Sciences in Raleigh.

The first dinosaur's appeared on earth at about 230 million years ago. the first dinosaur was called Eoraptorc, found in Argentina and Brazil. It was a small meat eating creature. Scientist think there may be older dinosaurs out there.

quite, parasaurolophus runs fast but it gets eaten.

it ate fish it scavenged and ate tiny animals

Dinosaurs have been alive in the Mesozoic Era. The Mesozoic Era consist of three time periods the Triassic, Jurassic, and Cretaceous. The Triassic is the oldest part of the Mesozoic Era. The Cretaceous is the youngest part of the Mesozoic Era. The Triassic period had started 227 million years ago and ended 22 million years later. When the Triassic period ended the Jurassic period started. The Jurassic period started 205 million years ago and ended 61 million years later. After the Jurassic period came the Cretaceous period. The Cretaceous period started 144 million years ago and ended 79 million years later. The dinosaurs have been alive ever since the beginning of the Triassic period and are still alive today. But the dinosaurs that are alive to this day are the evolve creatures of those in the past.

volcanoes, floods, earthquakes and tornadoes

Kansas has no state fossil or state dinosaur. However, birds are a type of dinosaur, and Kansas's state bird is the Western Meadowlark.
