Fossils of the Pittsford Shale

In additiion to the eurypterids, the shales and dolomitic rocks of the Salina Group contain other fossils, including clams (pelecypods), Lingula sp. (an inarticulate brachiopod), ostracods (small beanlike arthropods) and some shrimplike creatures (phyllocarids).  Many of the fossils collected from Pittsford and nearby areas are still under investigation.  Some fossils found  are only parts of an animal. Since (molting is a necessary process in arthropods in order to grow to larger size, this process increases greatly the probability of preservation in the fossil record. The creatures have to be reconstructed as best we can with the most current data we have from the parts we have discovered. 
   Work is currently in progress to reconstruct a pterygotid eurypterid, based upon isolated parts  found  at a number of sites in upstate  New York.  The pterygotids were, without doubt,  carnivorous eurypterids and were probably the 'sharks'  of the Silurian waters and may have grown to several feet in length.  Such  beasts would have had no problem attacking phyllocarids and the smaller eurypterids like
Hughmilleria.
   The study of fossils, paleontology,  is an ongoing process .  New discoveries lead to more precise reconstructions of the prehistoric animals and our appreciation of the life of the past. Reconstructing the pterygotid of the Pittsford Black Shale will be exciting.  It will be shared here, on the world wide web, first.  Stay 'tuned.'
   Another eurypterid,
Mixopterus, is a strange, somewhat scorpionlike animal. Very few specimens of this animal have been obtained, but the animal is well-known from the rocks of Norway. It may well have been a form that was quite capable of creeping up onto the Late Silurian land- scape.
