Westlohiana

This ancestor lived 350 million years ago and was found in Europe which is where I live Scotland.

It’s length is 30 cm which is surprisingly smaller than an average humans foot.

Some scientists think that it was an amphibian more than a true reptile.

The Westlothiana is thought to eat insects like spiders and what some people would describe as creepy crawlers although it is not proven to eat fish.

It lived in the same place as amphibians: rivers.
