The Hibbertopterus meadows would bring to mind the image of a seagrass flat interposed with towering mangrove forests. The colossal eurypterids would be grazing peacefully as shoals of shimmering Devonian bony fish dart frantically around them.

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.

I'm pretty sure Kabutops is mostly trilobite-based (in addition to horseshoe crabs). I'd also wager it's inspired by eurypterids (sea scorpions). The -ops part of its name might come from Triops, or maybe even Triceratops?

Sea scorpions (or Eurypterids) were big predators in the seas around 400 million years ago. Strong pincers would make an easy meal out of a trilobite. Some Eurypterids could grow as long as me!!

I’ll add to that, Kabuto’s evolution Kabutops is based on trilobites and possibly eurypterids (“sea scorpions”, though not true scorpions but ancient relatives of arachnids). The name Kabutops is probably a reference to Triops, or possibly even Triceratops.

design consists of a mix between a and the still-living (considered a living fossil) horseshoe crab. has a head similar to the trilobite’s cephalon, but it more resembles prehistoric arthropods that hunted in the seas.

This new critter is fascinating; related to the predator Anomalocaris and filter-feeder Aegirocassis but living like neither, it seems to be a mud-grubbing sweep-feeder, like some of the eurypterids that evolved later in the Paleozoic.

I favor the Eurypterids! They were giant fresh water Arthropoda that ruled the streams and listed with the antediluvian might of their terrible pincers!
