RARE Eurypterid Fossil – Eurypterus remipes | Silurian Sea Scorpion | Bertie Group Waterlime | Herkimer County, NY USA | Genuine with COA

Description

RARE Eurypterid Fossil – Eurypterus remipes

Discovered in the renowned Fiddler’s Green Formation (Waterlime), Bertie Group, Herkimer County, New York, USA, this is a genuine and exceptionally preserved fossil of Eurypterus remipes – one of the best-known species of extinct marine arthropods commonly referred to as “sea scorpions.”

This specimen dates to the Silurian period, specifically the Pridoli stage (~419 million years ago), and is part of one of the most scientifically significant eurypterid deposits in the world. The fossil is embedded in dolostone-rich waterlime, a fine-grained sedimentary rock that contributes to the exquisite preservation of fine anatomical details, such as leg segments, telson (tail spine), and prosomal (head) structures.

Fossil Overview:

• Species: Eurypterus remipes
• Common Name: Sea Scorpion

• Geological Age: Silurian Period – Pridoli Stage (~419 Ma)
• Stratigraphy: Bertie Group → Fiddler’s Green Formation (Waterlime)
• Depositional Environment: Restricted lagoon or marginal marine setting – shallow hypersaline waters conducive to preservation

• Biozone: Not formally designated, but correlates with Eurypterid Lagerstätte horizons

Taxonomy:

• Kingdom: Animalia
• Phylum: Arthropoda
• Class: Merostomata
• Order: Eurypterida
• Family: Eurypteridae
• Genus: Eurypterus
• Species: remipes
• Formal Description By: DeKay, 1825

Notable Significance:

• Eurypterus remipes was the first eurypterid formally described in North America, and is the state fossil of New York
• Represents an extinct lineage of marine predators that predate vertebrate dominance in aquatic ecosystems
• Often regarded as an important reference species for Paleozoic aquatic arthropod evolution
• Specimens from this locality are globally regarded as museum-grade fossils
