thefirst animal extinct was the euridan fauna and it came from the time of pre cambrian. it is believed to have lived before the dinosaurs and was also known to be a plant
There are many folkloristic legends about it, however,the dinosaur Amphicoelias fragillimus is said to be the biggest prehistoric animal.
I believe the biggest extinct animal is dinosaurs.
The tallest and heaviest dinosaur known from a complete skeleton is the Brachiosaurus. That is all I know from knowledge. Sorry I wasn't much of a help.
It was Argentinosaurus, 36 meters long, it was even larger than the what is now, the Blue whale. Not only that. It weighed more.
Worlds largest animal: Blue Whale
Aurochs
No there are many other extinct volcanoes that are larger.
They would all die and we would lose the worlds largest land animal and all of the future would hate our generation.
no infact the worlds largest animal is the blue whale
The largest land based wild animal is the elephant, but the largest animal currently on earth is the Blue Whale.
sinead of course
No it is not but one thing that I like is that the Siberian tiger is the worlds largest animal
An octopus is the largest creature without a spine.
The Sperm Whale (Physeter Macrocephalus) (Cachalot) is the animal with the largest skull in the world (both in general and aquatically).The African Bush Elephant (Loxodonta Africana) is the largest-skulled terrestrial animal in the world.The extinct aquatic animal with the largest skull would probably be either a Mosasaurus Hoffmannii or a Carcharodon Megaladon.The Titanoceratops Ouranos is the extinct terrestrial animal with the largest skull.
The blue whale qualifies as the world's largest animal.
The largest prehistoric animal ever was the Basilosaurus which was a 59 foot whale. The largest crocodilian was the 39 foot long Sarcosuchus Imperator.
