I often wonder just how many different species of animal there were on the planet throughout its history, seeing as how we only have fossils from a limited number of them. I'm sure there were far more dinosaurs than we could have ever imagined, but are lucky enough to know about the ones we do. Just think about how many different species of animal are on the planet today, and the relatively few species of extinct animals we know about.
