| Hughmilleria socialis Sarle |
| Drawings of Hughmilleria socialis showing some of the structures characteristic of eurypterids. All of these structures can be collected as isolated fossils. Often, remains found consist of isolated parts (telsons, swimming legs, tergites, walking legs, metastomas, paddle joints, etc.). Commonly, remains are found in windrows--collections of eurypterid debris oriented into linear deposits on bedding planes. Associated fossils, eg. plants and cephalopods are also often found in windrows. This drawing is based upon the reconstructions of Clarke and Rue- demann (1912). Clusters and windrows of euryp- terid parts are exceedingly com- mon within the Pittsford Member of the Vernon Formation in Upstate New York. A cluster of carapaces and associated parts can be seen in new photos of specimens re- cently collected near the type lo- cality in Pittsford, New York. Current research is directed at a new site revealing the entire strata associated with the Pittsford Shale at Spring House Commons. This is probably one of the last sites to be available for study as most of the village in now overwhelmed by commercial development. Little land is left for future exposure of the Pittsford Shale. Results of the current study are being published in several journals. |
