Kabutops is super weird, and almost evil looking?
It's a trilobite, but also a eurypterid?

It's hard shell makes it look very mean and predatory.

Arthropods were simply enormous. Arthropleura, the giant millipede (up to ~2m long), crosses a fallen trunk. A 70cm scorpion, Pulmonoscorpius, cacthes the small lizard-like Westlothiana. The 1.5m eurypterid Hibbertopterus clumsily crawls onto dry land.

The Oldest sea scorpion is Pentecopterus from the Ordovician Winneshiek Shale in Iowa. Despite this acclaimed status, they were relatively derived meaning it's possible we can find earlier eurypterids in the Cambrian.

An extremely wide eurypterid that grew up to 2 meters in lenght, the reason for these proportions is that it was better adapted for use of its walking appendages

ALT: meaning wide body, it was the original name for the genus, but it was already in use by a beetle

I am going to attempt to reconstruct the extinct giant Eurypterid Hibbertopterus trundling along out of water.

Paleo friends: how does one find the really meaty reference material? Any good sites/experts I should visit/talk to?
