Whetstone gulf & Pulaski formations in northwestern NY

[Nautiloid]

Last fall I went on a fossil hunting trip to a creek in Adams, NY. Along this creek were exposures of the Whetstone Gulf and Pulaski formations. There were many different layers, each with different fauna. Some layers were barren, while others had many species. Some of the most common fossils were cryptolithus and triarthrus trilobites, as well as brachiopods, bivalves, gastropods, ostracods, and straight shelled nautiloids. Some layers contained pyrite and some of the fossils in these layers were partially pyritized. (Including some of the trilobites!!).

Here is a spine from either a very large triarthrus or some other species. It has some beautiful rainbow coloration.

Here are some of the cryptolithus trilo’s.

Here are some of the triarthrus cephalons. (I didn’t find any complete ones).

Here’s a little bivalve and a straight shelled nautiloid that is pyritized in the center.

Some layers also were loaded with super long crinoid stems and I managed to find one tiny calyx.

I am envious of those Cryptolithus! Good haul!

Thanks!! Cryptolithus is one of my favorite trilobites to find. I love their odd shape!

Nice assortment of fossils - congrats!

 

Is there any way that we could see the tiny calyx you found?

Here’s the tiny calyx. It’s only about the size of a fingernail but it’s still very neat. Only calyx I’ve ever found!!

Nice success! I wasn’t quite as lucky in the areas you were in. I will have to do an update soon on some recent adventures........Just gotta find the time  .

Thanks!! Maybe next time you’ll have some better luck there.
