What die when it live and what live when it die?

Answer 1

Well, Dinosaurs descend from the reptile family, as do snakes, turtles, lizards, crocodiles and komodo.

So these are animals related to the dinosaurs and all are living species.

[An important feature to note is that those which survived the effects of the meteor impact in Mexico, (65 million years ago, and known to the geologists as the K/T boundary) all lived underground or in the water. Top predators such as sharks must have had a good day. ]

The closest to the dinosaur family today is the Tuatara of New Zealand, of which two species still exist. These are often referred to as living fossils of the dino family, but in the 200 million years, the Tuatara itself will also have evolved.

They are known as Sphenodontia, and the dontia bit refers to the small tooth on the end of their beak which they use to cut through their shell.
