Paleo Series [Part 1/3]

A size comparison of the first fifty primitive extinct animals of the Paleo Series. These guys range from the very beginning of life on land in the Paleozoic Era to the animals that lived in the shadow of the dinosaurs. I had to scale this one down because most of the animals are on average a lot smaller than all of the other series. It also probably has the least amount of well-known animals of all of the series.
Also, just so you know, there is not a single dinosaur in this entire picture. Not all extinct things are dinosaurs, you know!
