Part 3- Aren’t you glad that this is extinct and can’t eat you?
I just thought that the first picture was funny, and gives a decent size comparison. The second picture is of Mixopterus, a spiny eurypterid that is probably the ancestor to modern day scorpions.
Eurypterids (“broad wing”) are extinct arthropods, related to arachnids and horseshoe crabs. They were shallow-water predators that lived from the Ordovician to the Permian, with a global distribution. Earlier eurypterids were marine, while those that lived after the Pennsylvanian were freshwater.
They have a carapace, a jointed body, compound eyes, paddles used for swimming and digging, and a tail called a telson. The largest species of eurypterid was Jaekelopterus rhenaniae, which reached a terrifying estimated 8 feet 2 inches. Pterygotid eurypterids were around 7 feet 7 inches. On top of this, they had strong pincers (chilicera) and were quick swimmers. And could also most likely walk on land. Thank god these aren’t around in our lakes and oceans, eh?
