Our Collecting Localities
For obvious reasons, we keep our collecting localities confidential, but will share some of them with other field workers in return for similar courtesies and discretion. We are actively working all of these localities, except Craigleith, which is now protected and has been over-collected. All of our other localities, except the Triarthrus locality in Upstate New York and the Tay Township Anataphrus exposure are active limestone aggragate quarries and are therefore closed to collecting without the express permission of landowners.
These species lists are in stratigraphic order and are very much under construction. They are, however, guides to the clusters of species in Ontario and Upstate New York localities.
