Why did the pterodactyl become extinct?

Answer 1

The diplodocus was extinct because not one but too giant 20 km long astroids hit the earth in a unspeekable speed as the fate of the diplodocus's exsistence faded with the rest of the giant reptiles leaving only mammals to pick up the peices and repopulate the earth witch soon created early humans but that is another story.

Answer 2

Scientists can only theorise on why the Diprotodon became extinct, and three possibilities have been propounded. Together, they may are believed to have contributed to the extinction of the Diprotodon.

Climate change is one such theory. Climate change is known to have changed the nature of interior Australia, with vegetation on which the Diprotodon gradually being replaced by more arid plains.

A second theory is that the Diprotodon died out with the arrival of the Australian Aborigines on the continent. Diprotodon were large, slow-moving creatures and easily hunted. This theory is supported by the fact that Diprotodon bones have been found with butchering marks.

The third theory also implicates human habitation, but more indirectly. Aborigines were known for the way they used fire to drive out game, and this fire regime is believed to have changed the landscape, and thus the ecosystem, on which the Diprotodon depended.
