Frequently Asked Dinosaur Questions. Question #11: How many dinosaurs were there? Answer: There are over dinosaur 500 genera (the plural of genus) that have been found, named and scientifically accepted. There are about an additional 100 genera that are dubious (these are frequently referred to as nomen dubium).
In addition to all the animals, there are between 10 million and 1 billion species of bacteria and archaea. What's more, the number of species today is thought to represent only 1% of all species that have ever lived, since mass extinctions in the past have likely killed off as many as 97% of all species.
