Dinosaurs

pteranodns werent dinosaurs they were pterosaurs because dinosaurs could not fly.

Yes. Compsognathus was a meat-eating dinosaur, even though it was only the size of a chicken. Its prey probably included insects, lizards, and small mammals.The eggs laid by Compsognathus was one of the smallest eggs in the world.

Because there where fewer insects

There was a lot of chalk because a large area of the continents was covered by warm shallow seas, as a result of that there was a lot of marine limestone. You can also find chalk with many types of algae that flourished during the cretaceous period.

An example of a landform would be the white cliffs of dover. There are also landforms in Sussex, the isle of Wright and East Dorset

We don't know. Venom isn't something that fossilizes well. Although there are venomous dinosaurs in the movie, "Jurassic Park," that's just speculation. There MIGHT have been, but nobody's found any evidence to that effect yet.

Velociraptors likely possessed superb sensory abilities. Like the other dromeosaurs, and much like their close relatives, the birds, they had very well developed eyes and were quite possibly tetrachromats (possessing four types of color receptors, like modern birds and many other reptiles, and unlike humans which possess only three), meaning that they likely saw a greater range of colors than we do. Furthermore, an analysis of their scleral rings suggests that they may have been nocturnal hunters, suggesting that they may also have possessed good night vision. An analysis of dromeosaur olfactory bulbs also suggests that their sense of smell was acute, possibly on the level of some modern vultures which rely on their sense of smell to detect carcasses at long range. All in all, Velociraptors were very well equipped to home in on their prey using a full range of senses, from smell to sight to sound, depending on the particular situation.

Theory states that the meteor, which destroyed everything living dinosaur in that time, had a mass simliler to the size of Texas.

Only herbivorous or omnivorous dinosaurs would eat trees

The archaeopteryx where a species that lived during the late Jurassic period about 150 million years ago. They lived in marshy areas or swampland ( much of earth was marshy swampland at the time )

Yes, a giant mosasaur can refer to a Tylosaurus, as Tylosaurus is one of the well-known genera of mosasaurs. Mosasaurs were a group of large, marine reptiles that lived during the Late Cretaceous period, and Tylosaurus was characterized by its elongated body and powerful tail. It is recognized as one of the largest members of this group, reaching lengths of up to 50 feet.

'Dinosaur' refers to any member of the class Dinosauria, whereas 'human' refers to any member of the genus Homo. Thus there are many different species of dinosaurs but only a handful of humans. Additionally, dinosaurs typically had feathers and/or scales (like birds), whereas humans have fur. Dinosaurs also existed for a duration of at least 100 million years, and a geological era, approximately 100 times as long as humans. Dinosaurs also were reduced to the theropod branch of the formerly large evolutionary tree approximnately 75 million years ago, and now exist as the class Aves.

Non-avian dinosaurs existed from 231 million to 65 million years ago. Birds, a branch of the dinosaurs are still around today.

Because of the ice age melting it caused the wolly mammiths to become extinct and many other animals.

a t-rex anyway, you coulda post a message for this.

i would be a therizinosaurus

Carnivores ate plant eaters

exept from huge ones like the apatosaurus.

Somtimes they go crazy and carnivores eat carnivores!

plant eaters ate plants and fruits and wat

paleontologst ;]

Dinosaurs died out 65.5 million years ago, so finding a 3 million year old dinosaur bone is impossible. However, if someone did (and it wasn't just a bird bone), it would be worth a lot, because it would prove that not all dinosaurs died out when we thought.

search shows most say a hatchling

but i say maybe dinoette or babydino

The male bichir has a broader penus fin than the female. The females are mainly larger in size than the males.

Yes. Wolves coexist with avian dinosaurs and sometimes feed on them.

Dnosours became extinct because a large meateorite hit the gulf of Mexico and then killed off the dinosours.

The Egyptians, then the Greeks, Romans, Celtics, Vikings, Saxons, Middle ages, Dark ages, Idustrial ages and then information ages were we live now. That is near enough for an S.A if your doing one? Not i just had to annoy the internet

Becase the word 'Dinosaur' means terrible lizard.

The Seismosaurus became extinct by what most scientists believe; by meteors.
