While Eurypterids (“Sea Scorpions”) are uncommon fossils worldwide, New York state and Ukraine are one of the few places where conditions for preservation have been ideal.
They were large arthropod predators during the Silurian and Devonian, reaching a maximum length of 2 meters
Eurypterus (Baltoeurypterus) tetragonophthalmus Fischer, 1839 , is presumed to have crawled along the seafloor, using its grasping pincers to seize trilobites and other prey.
This fine example is a big Adult ( almost 11 cm), compound eyes are 3D , not flat.
Swimming paddles and walking legs are restored.
The segmentation of the meso- and metasoma is well detailed.
Telson preserves some spines.
Matrix is 16 x 19 x 3 cm.
Specimen is 10,8 cm.
Restored in Mesosoma( from the 4th to the 9th tergites in the middle as the stone plits badly).
Matrix is been restored as it was broken in two.
The various restorations are justified by the size of the specimen.
