Yes, there are dinosaurs alive today and dinosaurs are not considered extinct.
There was a mass extinction event about 65 million years ago, which killed off most dinosaur groups, such as the hadrosaurs, stegosaurs, allosaurs, tyrannosaurs, ceratopsians etc.
So there are no dinosaurs alive today that existed 65 million years ago, like Tyrannosaurus or Triceratops etc, that is, non-avian dinosaurs.
It is now widely accepted by paleontologists that birds are theropod dinosaurs and therefore the group dinosauria has survived to the present.

In response to the first answer, birds are the ONLY descendants of dinosaurs, and no other reptiles.

I have modified the answer to btter reflect current thinking.
-Dinosauria.

Actually the closest species to the dinosaur is the Tuatara considering it was around back when the dinosaurs went extinct
--------------------------------------------------------------------------------
No, it isn't. The tuatara is a sphenodontian and while members of that clade indeed did exist during the Mesozoic, they were not and are not the closest relatives of dinosaurs (they are no more closely related to dinosaurs than lizards or snakes). The closest living relatives of dinosaurs are the birds (who are actually dinosaurs themselves) and after that, the crocodilians, which are archosaurs (a group to which the dinosaurs belong).
yes
Scientists consider birds a type of dinosaur. Birds are still alive and abundant.
Dinosaurs are not alive any more duma$$
Crocodile is an ivolved dinosaur if that's any help
None. There are none alive. If any of them were smart, they wouldn't be extinct

The dinosaur tracks dinosaurs were alive from the late Cretaceous period up to the Phrongassic period.
The oldest dinosaur was alive in the triassic period and is called the Melanorosaurus.
No.
"Biotic" refers to anything that is alive. Dinosaurs were alive, so they were biotic.
It depends what type of dinosaur it is, most dinosaur books have pictures of them though, but most of them looked like big lizards or monsters.
No the rhino is not a dinosaur because dinosaurs have been gone for thousands of years and rhinos wouldn't be alive if it was a dinosaur and that is your answer.
The earliest known dinosaur Eoraptor lived about 230 million years ago in the Triassic period.
