420 Million years before the reign of Mamdani, two Acutiramus wake up from their daylight slumber as thousands are Eurypterus begin to invade the shallow, warm waters of New York.
This is the Fiddlers Green or Bertie Formation, a Silurian lagerstätte known for its eurypterids🧵

Excited to see this restudy of the large Devonian scorpion Praearcturus out today - neatly falsifying some recent supposition that it was not a scorpion at all, and supporting a synonymy between three different species that I've suspected for quite some time!

A bountiful crop.
I still find strange things in the woods.
Amazing reconstruction of a famous eurypterid site! Here's one member of that fauna, Acutiramus macrophthalamus (UMMP IP 86635).
Some of the bugs enjoying my chicory today.
What time is it? It’s #Cheliceratime!

All the basic infos are here but if you want to learn more, there’s more in the thread below!⬇️🧵

Here is a "sea scorpion" or the Eurypterid Eurypterus remipes. This specimen comes from the Upper Silurian Fiddler Green Formation in Herkimer Co, New York. This happen to be the state fossil of New York. Some such as the Pterygotids could reach enormous sizes!
