CIURCA COLLECTION
LARGEST PTERYGOTID EVER FOUND IN NORTH AMERICA, PERHAPS THE WORLD.
SPOHN HILL NEAR SPINNERVILLE, NEW YORK.
The PTERYGOTIDS represent one group of the EURYPTERIDS,  They are notable not only for the great size they attained, but for the development of their chelicerae into formidable pincers. Pterygotids also have their telson developed into a great swimming 'flipper."  This, together with their streamlined body, suggest great agility in the Silurodevonian waters they inhabited.

Like all arthropods, the pterygotids were made up of many segments and joints--tergites, swimming leg joints, sternites, a telson and other structures.  These pages will illustrate many of the various structures that constitute pterygotids--THE GREATEST ARTHROPODS OF ALL TIME!
