Dinosaurs

No. Only mammals have nipples.

==================================

No.

Animals that reproduce using eggs, either retained internally (oviparous) or laid externally (that is to say amphibians, reptiles and birds) feed their offspring using the yolks of their eggs.

However, mammals produce young that are fed on Mother's milk and the nipples are the tubes by which this milk is obtained by the young. Thus only mammals have nipples.

Dinosaurs are not mammals, they are reptiles and they laid eggs.

Paleontology is the study of fossils (any evidences of ancient life) in order to compile information about the history of life on Earth. Examples of paleontology related activities would be the search for and recovery of fossils, the reconstruction and cleaning of fossils, identification and cataloging of fossils, preparation of museum exhibits, and creating hypotheses and theories on ancient organisms' evolution and behaviors.

40 meters long, which is the Siesmosaurus.

There is not a pacific place where reptiles live. Reptiles live in all habitats except from Antarctica where it snows all the time. Reptiles can live in hot deserts, swamps, tropic jungles, dark caves and even in the ocean there is many places where they can live you see.

Reptiles that were coexistent with dinosaurs are still around. Animals like the crocodile and tuatara. The theropoda family, which included the T. Rex and the other bird-like dinosaurs continue on as the birds of today, but the larger members from the time of the Triassic only remain as fossils.

Dinosaurs are not mythical they lived hundreds,and hundreds,and hundreds of years ago

This might not be exactly straight forward, but they evolved when they needed to adapt to current changes in the world or current area that they live or occupy. -<3 Super Possum on GaiaOnline.com

In 1990 the remains of a large meat-eating dinosaur were found near the 4000 meter peak of Mt Kirkpatrick in the Trans Antarctic Mountains. The fossils were excavated in 1991 by Bill Hammer from Augustana Collage in Illinois, USA, and identified as the new theropod dinosaur Crylophosaurus, the frozen-crested lizard. Crylophosaurus was around eight metres in length and sported a strange crest on its head, giving it a passing resemblance to Elvis Presley in his more bouffant days.

First of all, there are noticeable skeletal similarities between birds and the carnivorous dinosaurs known as theropods. Some of the smaller theropods such as archeopteryx, microraptor, and velociraptor (which was much smaller than was shown in Juraasic Park) were extremely birdlike, not just in their skeletons but in possessing large feathers identical to the flight feathers of birds. Furthermore, soft tissue samples have been found preserved in tyrannosaurus bones. Chemical analysis of the preserved proteins finds that they are very similar to bird proteins.

Contrary to the popular depiction of dinosaurs carrying their arms with the "palms" facing downward or backward, they actually carried them facing inward and could not turn the wrists to make them face downward. Overall these posture in many dinosaurs was similar the the posture of bird wings when at rest.

We have proof that a Triceratops lived.

scientists have found fossils of a Triceratops scientist times they have also found other fossils of dinosaurs similar to the Triceratops.

They are not carnivores (carnivore's) they are herbivores (herbivores).

herbivores are animals that eat only plants.

Carnivorous are animals that eat only meat.

The Triceratops gets its name from the word tri.

The word tri means 3.

Extinction is where a species of a animal/plant totally dies out and there are none left, like Dinosaurs for example, or Dodos.

Theropods were the killers of the dinosaur world, for exampe tyrannosaurus rex was a theropod. Other examples are Coelophysis, Ornithomimus and Dilophosaurus.

Titanoboa was a huge snake that lived between 60 and 58 million years ago. That was during the Paleocene epoch of the Paleogene period, the first period of the Cenozoic era. Its fossils were found in Columbia, in South America.

Archaeopteryx was the first animal discovered that had both defining bird and dinosaur traits, as if it was an evolutionary link (in reality, however, it was only closely related to the ancestor of birds). These traits include feathers, wings, and wishbones of birds, and the long tail, fingers, and teeth of dinosaurs. It was the first evidence that birds evolved from dinosaurs.

Herbivores are what eat plants.

An allosaurus could grow to be 12 meters long.

Dinosaurs came in different sizes, just as animals today are different sizes. There can be many animals larger than SOME dinosaurs.

how old a dinosaur is all depends on what type of dinosaur it is. it also depends on whether or not the dinosaur is extinct or still living in a way. such as birds. some birds decended from dinosaurs so the dinosaur lives on in an evolved way. making your question unanswerable , sorry :) x

This answer is literally impossible. it is based on opinions. mine is Utahraptor. my friend's is Tyrannosaurus.

Birds and crocodiles are the closes living relatives of dinosaurs, with birds being closer.

lets first take a look at the relation between dinosaurs and birds. If you look at the skeletal structure of a dinosaur and a bird side by side, you'll notice a few similarities. First, look at the hipbone of a dinosaur; it is turned backward, just like a bird. Second, by watching some birds of prey, you can see how a dinosaur may have looked. They bob their heads, they strike with their talons, etc. Additionally, many dinosaurs are now known to have had feathers.

Compsognathus wasn't the smallest dinosaur. It weighed somewhere between 2 and 8 lb and was about 3.3 feet long.

There will be less competition for breeding. The males of social animals often have intense battles for the pack's females. However, two males of a solitary species may still meet each other during the breeding season in search of a female and fight. It's just that these fights will be less likely and less intense. Also, if a solitary animal catches prey, it doesn't have a social obligation to share the food; it can eat the whole thing.

An extinct, swimming, fish-eating reptile (a plesiosaur) that had four flippers and a very long neck.
