Euryptids, or 'giant sea scorpions', were among the largest arthropods ever to have lived.

For ~200 million years (Silurian to Late Devonian), they scuttled at the bottoms of oceans, lakes & swamps. Then they disappeared & only their cousins, the horseshoe crabs, remember their passing.
Size comparison of six of the largest eurypterids (sea scorpions). They are (from largest to smallest): Pterygotus grandidentatus, Pentecopterus decorahensis, Acutiramus macrophthalmus, A. bohemicus, Carcinosoma punctatum, and Jaekelopterus rhenaniae.

Day 10 of #AugArthroAwe - Jaekelopterus

what in the massive shrompion nonsense 🦐🦂

#invertebrates #SciArt
drawing in black ink and white fill on a light green background of a Jaekelopterus, an extinct invertebrate that looks like a mix of a shrimp and a scorpion, with small claw like apendages at the front with large eyes, then 8 tiny legs, followed by two larger closed claws, a long segmented body, and a kind of shrimp tail.

Gonna do a taxonomic revision of big eurypterids so I have an excuse to establish Jaekelopterus hydei

The largest arthropod ever was a sea scorpion. Jaekelopterus stretched about 2.5 meters, longer than a person is tall, hunting the seas 400 million years ago with claws half a meter long. Nothing with an exoskeleton has come close since. 🦂 🧪 #FossilFriday #HowToBuildAGiant Artwork by Dani Navarro

You'd have to be sooo off your rocker to not want to eat an Eurypterid steak. Look at all the meat on these guys. I bet they tasted so good
Nice diagram of Eurypterus with body parts labelled.

While lots of fossils are known most are rather small which made the made it a big surprise when suddenly parts of a 1,5 m long Jaekelopterus turned up.

The Jaekelopterus aquarium/ exhibit, lots of tunnels and layers, and some merch you can get at the gift shop of your favourite eurypterid

For #invertefest, here’s a diorama that includes Jaekelopterus rhenaniae (lower right), a giant up to 2.6 meters long aquatic arthropod that lived some 390 to 400 million years ago.

This jaekelopterus wants to wish you a happy new year :3 💜
This was supposed to be my #Scisketch, but I really went over my time limit >w<
They've got little crab claws! 🦀

Please be kind to yourself throughout the year. 💜

A digital art piece of an arthropod from the genus jaekelopterus, an extinct aquatic hunter. They are holding their claws together to form a heart, above which a tiny heart floats, and are wearing a pink and yellow party hat on their head with "2025" displayed on the front. Their eager eyes are an almost luminous blue, and they have a slight blush on their face. Their body and legs are mottled blue and gold, with stripes and spots of both colours marking them.

This is a Giant Eurypterid made by Prehistoric Pals, it's the state fossil of New York. yes they really could get this big

Telucaron is a giant arthropod that dwells in the murky water of the southeastern swamps. It ambushes terrestrial prey by dragging them underwater with a vice grip from its powerful chelicerae.

Ever? That would be the extinct sea scorpion, Jaekelopterus rhenaniae, which was the size of a saltwater crocodile.
