How many fossils have been found?

That's an interesting question!

In terms of the number of individual fossils there are probably countless billions. Most large Natural History Museums will have a collection of several million. However, as you probably know there will be multiple specimens for most species. For example we have lots of different fossils of T. rex, these even have names like 'Sue' and 'Jane'. The number of different kinds of fossils (species) is much less, I think the figure is a few hundred thousand. In reality there were probably many more species in the whole history of life, but many of these never left a single fossil and others have yet to be dug up!
