How many prehistoric animals were there?
There is an enormous variety of life on Earth, currently around 10 million species. But as many as there are now, 99 per cent of all species that have ever lived on Earth are now extinct - that makes a total of over five billion species in the history of the Earth.
What is the largest prehistoric animal?
Elephants, mammoths, and mastodons (Proboscidea)
