Dinosaurs

It is likely to have been a generalist capable of feeding in both shrubs, open ground and even alongside the shores of the lagoon. It most likely hunted small prey, seizing it with its jaws if it was small enough or with its claws if it was larger.

There were many different types of dinosaurs; some were tiny and some were enormous. The smallest known dinosaur was Epidexipteryx, weighing only 0.36 lb. The largest known from well preserved specimens is Argentinosaurus, weighing up to 80 tons.

It really wasn't an era. An Era was a much longer period of time. It was called the "Jurassic Period".

Brontosaurus is an invalid name for Apatosaurus excelsius. Apatosaurus had forward pointing teeth shaped like leaves in the front of their mouth. Their purpose wasn't for chewing but simply for cropping plants that the Apatosaurus would then swallow.

Highly unlikely. There may have been some species of Monotremes living contemporaneously with the dinosaurs, but it's unlikely that there were any like the platypus.

The biggest dinosaur was infact the biggest animal ever!

Its called the LIOPLUERODON. It lived in the sea and actually ate anything even sharks!One flipper is 5 metres long and from head to tail it was 25 metres long. It weighed close to 150 tonnes! If washed up on land its lungs would be suffocated by its own weight!

Depends what you mean. Crocodiles have not evolved much from the ages of the dinosaur but their size has changed slightly. Turtles also share the fact that they were bigger back in the dinosaur times. Animals from the dinosaur ages can't still be alive because that mean that they would be about 65 million years old. So the answer is kind of, because although they are a lot like animals from back in the Jurassic and Triassic ages, they are not the same as those animals.

Brachiosaurus eats leaves and branches of tree, long neck helps brachiosaurus get more foods in high trees.

In a strong sense, you're right to ask this. It's likely that modern birds evolved from theropod dinosaurs. Recent fossil remains of velociraptor have proved that they had feathers and wings, an expert said that if velociraptors were found alive today then we'd probably think they were odd looking birds. Some biologists think that birds and theropod dinosaurs should be classified in the same group, although no modern bird has teeth which theropods (which includes T. Rex) had in spades, so the classification might have to a little looser to include them all.

So, you've a strong case to say that the dinosaurs didn't completely disappear - they're still here as birds.

Dinosaurs survived using a variety of adaptations, just like modern animals do. The exact adaptations depended on a dinosaurs niche and predators.

For example, ankylosaurs had armor to protect them from predators. Sauropods had long necks that they could use to reach vegetation high in the trees. The carnivorous theropods often had powerful jaws to dispatch their prey.

http://discovermagazine.com/2005/dec/largest-pterosaurs says that foot prints of an 18m wingspan pterosaur was found, but Hatzegopteryx is the largest one known from bone fossils.

There are millions of dinosaurs left in the world. They are called birds. There are none of the four legged terrestrial type pictured in the text books, such as T-Rex. They were all killed about 65 million years ago. Only animals weighing less than a few pounds survived the great extinction. Dinosaurs, except for birds, all weighed too much. It is hard to believe how small our ancestors were.

I am not positive, but when you look in pictures and illustrations you usually see grassy plains, mostly rainforests, and sometimes dry cracked deserts. . And you have to think about man-made damage, there weren't any people to destroy land for uses, so the plants and living things, even nonliving organisms were untouched and very overgrown. So if this is for a school report or something, it would probably be the safest thing to go with rainforests.

Dinosaurs lived in the Mesozoic Era. This was a time between 230 million and 65 million years ago. The Mesozoic Era is divided into three time periods: the Triassic, Jurassic and Cretaceous periods.

From Wikipedia: http://en.wikipedia.org/wiki/Dinosaur The superorder or clade "Dinosauria" was formally named by the English scientist Richard Owen in 1842. The term is a combination of the Greek words deinos ("terrible" or "fearfully great" or "formidable") and sauros ("lizard" or "reptile"). Contrary to popular perception, the name was chosen to express Owen's awe at the size and majesty of the extinct animals; not out of fear or trepidation at their size and formidable arsenal.

No, however, some dinosaurs did have feathers.

The heaviest land animal of all time, the Brachiosaurus. The humerous-to-femur ratio was greater than 1.0 meaning the shoulders were higher than the hips. Other dinosaurs that were originally thought to be bigger or similar, such as Ultrasaurus or Supersaurus either turned out to be Brachiosaur or more related to the Diplodocus.

they live for a very long period of time. also they ate damien

None-avian dinosaurs first appeared in the Triassic period and were the dominant land vertebrates through the Jurassic and Cretaceous periods. At the end of the Cretaceous period, 65.5 million years ago, all non-avian dinosaurs went extinct. Birds, which are now classified as dinosaurs, continue to live to his day.

There have been fossils, and skeletons from dinosaurs. Scientists don't know if they were called dinosaurs back then, but their name says almost everything about them. They are DINO, and SAURS.

No. As far as we know, nothing existed 75 billion years ago. The universe is about 13.7 billion years old and Earth about 4.55 billion. Dinosaurs appeared about 230 million years ago and died out 65.5 million years ago. So dinosaurs were around 75 million years ago, not 75 billion.

There are no names of underwater dinosaurs because there were no underwater dinosaurs. Sea reptiles that lived at the same time as the dinosaurs were around. Names of these sea-living reptiles include: Liopleurodon, Opthalmosaurus and Tylosaurus.

Tyrannosaurus wrecks

Yes, dinosaurs were vertebrates as they had an internal skeleton and a backbone to support their large bodies.

The dinosaurs came onto earth approximately 245 million years ago. They became extinct about 65 million years ago.
