New York Fossil Trip - 2007


Fossil Sea Scorpion (Eurypterid) Trip to the Sillurian of New York, Plus a Triarthrus trilobite hunt



Pterygotus - this is one of the largest sea scorpions ever found

This specimen, from Langs quarry, is one of the largest complete sea scorpions ever found. It's a Pterygotus that measures a little over 7 feet. This is a cast; the original is now in a museum collection.


After spending most of our recent fossil hunts in Tertiary sediments, I thought New York state would be a nice change of strata. So, toward the end of August a trip was set. Larry Decina took us into central NY, into the heart of Silurian and Ordovician strata for a two day "DVPS" tour of various fossil sites.

We would be fossil hunting for Eurypterids, Triarthus Trilobites, and the large and elusive Dipleura trilobites.

The first day included a grand tour of central NY by Larry. He took us to many interesting sites including a Triarthrus trilobite site near Little falls, and a Dipleura site in central NY. We also stopped at Langs to arrange a trip into his quarry.

On day two, Larry departed. We began the day with Lang. He took us into the quarry, showed us how to successfully search for the Eurypterids (One must find concoidal fractures to break), and gave us a few hours to hunt. He stayed with us most of the time, helping Amy and I find potential rocks with Eurypterids in it. It was a very enjoyable experience. Lang was very patient with us. We never found a complete Eurypterid fossil, but we did manage to find a few nice partials of sea scorpions. That wasn't bad considering this was our first time into the quarry. Later that day we headed back to the Triarthrus trilobite site in search of complete trilobites (which we found) and then headed home.






Below are images and fossils from the trip

Larry is holding a cast of a Dipleura trilobite fossil

Here, Larry is graciously modeling a cast of a Dipleura at the Dipleura site. As one can see, Dipleura are quite large trilobites. However they are very difficult to find whole. We found segments and heads similar to the size of the cast specimen, but no complete ones.
