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
The research history of this formation unfortunately causes much confusion here because what was once the Bertie Formation is now the Bertie Group which includes the Fiddlers Green Formation, but certain authors, especially on the Canadian side still call it the Bertie Formation
This caused a little bit of a headache during the research phase for this piece but I think we have it now figured out and the Wikipedia page also got already some updates. Beyond that Fiddlers Green is rather straight forward. These near shore waters were home to many critters
most prominently the eurypterids which most likely gathered here to molt, away from large open water predators, but other animals like weird oncoceratid cephalopods and even some interesting marco-algae can be found here as well.
The most common large eurypterid from is Acutiramus, which might have been a largely nocturnal predator of softer prey. Interestingly no vertebrates have been described so far! Size charts by Discord member Montana.
