Eurypterid Sea Scorpion and Trairthus Trilobite Fossil Hunt


August, 2007

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

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






New York Fossil Sea Scorpion and Trilobite Fossil Hunting Trip - Sillurian and Ordovician of New York

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 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.

Here are some examples of Eurypterid rempsis found at Langs quarry.


a mostly complete sea scorpion fossil
Here is a larger Eurypterid fossil found. Unfortunately the telson or "stinger" is missing.

This is a smaller Eurypterid rempsis. The body is here, but the appendages are missing. Some parts need to be glued back on.

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.

Eurypterid Fossil Sea Scorpion and Trilobite Finds



eurypterid fossil
Eurypterid rempsis with the telson or "stinger" and a paddle missing.


eurypterid fossil
A positive and negative of a Eurypterid rempsis. This one has a complete body but no appendages.

This plate has a Eurypterid rempsis with the poastabdomen missing, but with part of a postabdomen on the right of the plate.


eurypterid fossil
This little guy has the postabdomen missing. However it has all of its appendages, including all of the little walking legs.

Yet another Eurypterid with the postabdomen missing.


Triarthrus trilobite fossil
Here is a complete Triarthrus trilobite. The head is a little smashed up.


Triarthrus trilobite fossil
Here is another complete Triarthrus.


Triarthrus trilobite fossil
Here is another. The head is good shape, but the body is dinged up a bit.
