Alot of animals are extinct. I've been researching this for a writing project and havent found much. I found something but I'm not sure if its true, and it said that 900 species have gone extinct in the past 5 centuries(500 years). Lots of websites talk about extinct animals, but when they talk about how many, they say something like "It's hard to say how many animals are extinct, considering we haven't even discovered all animals on earth."

There are no solid numbers on how many species of animals have gone extinct, but there have been 5 mass extinctions in the history of the world. It is thought that thousands of species go extinct every year.
