Dinosaurs

This is a awesome dinosaur it weighs 12.5 killos middle aged. BY CHILLAX AY

They lasted for over 160 million years until they became extinct as a result of the Earth being struck by a meteor about 65 million years ago..

Dinosaurs died out (except for birds) some 70 million years ago. Primitive homo sapiens (that's us) have been around for only a few hundred thousand years

brachiosaurs

Most dinosaurs with long necks and small heads were quadrupedal (four legged) herbivores (plant eaters) called sauropods, and there were many different species of sauropods. Some famous ones include Apatosaurus, Diplodocus, Brachiosaurus, Camarasaurus, Seismosaurus, Argentinosaurus, Ultrasaurus, and Titanosaurus.

Brontosaurus is an invalid name for Apatosaurus excelsus. Apatosaurus excelsus was 75 feet, or 23 meters, in length. That is as long as a Junior Olympic swimming pool.

Most carnivorous dinosaurs dispatched prey using their teeth and jaws. Large types that hunted large prey often had strong arms, which were used to hook onto prey securely, so that they could kill it. Some dinosaurs, such as Troodon and dromaeosaurs, had long, curved claws on their inner toe, which was used to hook onto large prey and maybe even to stab it. They probably relied primarily on their eyesight to find prey, but some, such as Tyrannosaurus, had an acute sense of smell.

the pachycephalosaurus was a dinosaur that had a hard bony skull, and probably a strong neck for it.

they appeared at the end of the cretaceous, were presumed plant eaters, and fulfilled a ecological niche presumably similar to elk or bighorn sheep. the males probably used their hard skulls to crash into each other to win females in the herd, much like most modern goats do.

there are many other dinosaurs that have hard heads (ceratopsians come to mind) and others with long, and presumably strong necks (sauropods). we could say that the tyrannosaur has a strong neck.

so your question is a bit vague. i hope this answer leads you to something that helps you out!

Shunosaurus had a round spiked tail.

Stegosaurus, also had a tail with four large spikes.

Darwin noticed that birds of the same species had developed different beaks over time when they were isolated into different sections of the island. The different beaks helped each bird eat more depending on the diet of that specific bird.

Wyverns are dragons. The wyvern subspecies of dragon has four limbs, whereas the usual type of dragon has six. The wyvern has wings instead of arms, much like a bird or a pterosaur.

Wyverns have also been known for their body length, which is unusually longer than a dragon's.

The megalosaurus ate other dinosaurs such as the iguanodon and the sauropod

For about 165 million years.

Dangerous Dinosaur Locations Tyrannosaurus:Hell Creek, Montana Spinosaurus: Egypt Giganotosaurs: Pategonia, Argentina. There are many more species of dangerous dinosaur but these 3 were some of the most dangerous.

This analogy can be completed in a number of ways. Dinosaur is to extinct as to Panda is endangered, is one solution. Another solution could be Dinosaur is to extinct as Sun Bear is endangered.

Sorry but no they are not real. The are, actual or smaller size replicas of Dinosaurs the had lived 65 Billion years ago. Currently no known Species of Dinosaurs live on the planet. The closest resemblance of a Dinosaur are birds, which have evolved from Theropod dinosaurs during the Jurassic period, that are currently not extinct. These Theropod dinosaurs a furthermore recognized as pterodactyls. Pterodactyls were the majority of airborne creatures in the Jurassic period and had the highest probability of survival.

Fossil evidence suggests that most dinosaurs (excluding sauropods) raised their young. There is no evidence I know of that proves Megalosaurus specifically did, but they probably did.

The dinosaurs existed as they evolved best to fit the ecological niches of the day.

Dead reptile running. of course not. life cannot evolve from non-life . fossils for example are dead, extinct.

A person who studies reptiles and amphibians is known as "herpetologist." However, a "batrachologist" is someone who's study focuses solely on amphibians.

Herpetologists study reptiles and amphibians. It comes from the Greek term for a "creeping animal" and uses the ending -ology that is used to notate that it is the study of something.

Triceratops fossils have been found in the US states of Montana, Wyoming, Colorado, and South Dakota and the Canadian provinces of Alberta and Saskatchewan, and date to between 68 and 65.5 million years ago. At that time the area was a subtropical, coastal floodplain with various river deltas. It was forested with plants such as conifers, cycads, ginkgoes, ferns, horsetails, and early angiosperms such as primitive grasses and palm trees. Open areas would have had scattered trees and been covered in ferns. There were occasional peat swamps there, too. The region had distinct wet and dry seasons, and sometimes suffered from drought.

Many apex predators evolved to have curved teeth in order to lock their meal firmly into their mouth, allosaurus is an example.
