This is a very general question, kind of like asking "What do birds look like?"... there are many different varieties. Some had wings, some were huge, some were small, some ate plants, some ate meat. It all depends on the type of dinosaurs you're referring to.
They were huge reptilian lizards with sharp claws and teeth
There is some fossilized skin and it resembles an alligator's hide.
Color is still unknown.
Some dinosaurs had thick scaly skin like today's reptiles while others had feathers.
Considering that most eukaryotic cells have mitochondria and that dinosaurs are eukaryotes like all other animals that ever lived, it is certain that they did have mitochondria in their cells. In fact, birds are considered dinosaurs (they certainly descended from dinosaurs) and their cells have mitochondria, so we can be as sure as scientifically possible that dinosaurs indeed did have mitochondria.
No. Turtle are from a branch of reptiles completely separate from dinosaurs.
There has been research done that indicates that birds have evolved from dinosaurs. and mounting evidence shows that theropod dinosaurs are the ancestors of birds. Evidence includes countless skeletal similarities and evidence of feathers in many fossils. Feathers were thought to originally developed for warmth, and eventually evolved into flight aids.In face of this many scientists do consider birds to be descended from dinosaurs, if not a branch of them.Answer:Birds do have many features in common with theropods (bipedal carnivorous dinosaurs) which suggests that they had a common ancestor. We dont know that this common ancestor was a dinosaur though. It may well have been a bird (see related links). Looking back in time through the theropod fossil record, these dinosaurs appear to be more bird-like the further back in time you look. Raptors are known to have had feathers and were fairly bird-like, but Archaeopteryx was much more bird-like and lived much earlier and may have been an ancestor of the raptors. There is also a controversial fossil called Protoavis that was dated even earlier and was more bird-like still, with hollow bones like modern birds.So birds may have been around throughout the mesozoic era and even pre-date the dinosaurs. We have little record of them though because their hollow bones decompose very easily so are less likely to leave fossils. We do have some very ancient bird footprints though (see 3rd link).It may be more accurate to call the theropods flightless birds, rather than calling birds dinosaurs.
yes. It's not like it was discovered in space =D
no. Do they look like dinosaurs?
Birds looked like cockroaches when dinosaurs ruled the earth.
a dinosaurs head
long necked and fast
Dinosaurs looked like sh*t
bigger and scalier and had bigger teeth
it had dinosaurs and many extinct animals
DinoSquad is a show that was on television about a group of teens who could transform into dinosaurs. They had the ability to look like both a human or a dinosaur.
If you aren't familiar with dinosaurs you would probably mistake it for a T Rex
A Ghariel has evovled from the Dinosaurs from the Cretaceous period and it still look like it did then
Dinosaurs died out 65 million years ago. They did not exist 75 - 85 years ago.
Swan's feet look like the animals that they descended from several million years ago - dinosaurs. If ever you needed evidence that this was true, just go and look for yourself.
