Hey folks, I’m going to keep it short and sweet. I turned 31 yesterday (May 26th) so I had the day off from work. Still feeling inspired by my Lorraine group adventures I went out exploring again. I did lots of hiking...turns out so much so that I hiked out of the Whetstone Formation and into the Pulaski Shales. The Pulaski formation is just shales and sandstones (50/50 split pretty much) alternating....the upper whetstone grades into the Pulaski conformably so there isn’t an abrupt change. It just starts to have many more sandstone beds inter layered. So basically I thought I was in the upper whetstone and stumbled on a complete Flexicalymene granulosa just sitting in the stream already split open. I decided to stay close by and split a few pieces of shale and found 2 more!!! What!?! I thought I was in the Whetstone Formation and didn’t realize I was probably in the Pulaski shales till I got home. I had no clue the flexis could be found like that....or at all! Seems like if you find the right shales your gonna find one. I didn’t look through much shale at all so they seemed “somewhat” common. the Lorraine group gets weirder and weirder I tell you!! here are a couple photos This was the first one I found just sitting open already split. A nice prep would fix this guy up. The counterpart has the rest of the trilobite. This is the last one I found. Looks to be all there just mostly covered in shale. Saving best for last lol. Check this little guy out! This was the best Flexi. Scale in cm. It should come out great with a little air abrasion. Very lucky find for sure. Now I’m thinking I need to go back to the pulaski shale location I found last year! A happy accident (Hiked too far) on my birthday turned into a rare find! I have middle Ordovician calymenids now I have a late Ordovician example There is a Flexicalymene granulosa for sale on a well known fossil website that is labeled from the Pulaski shale so I made the connection there. If you google Flexicalymene granulosa it’s easy to find the listing. Flexicalymene granulosa isn’t even in the trilobites of New York book. To me that makes this find that much more special....totally under the radar and a total surprise to me. Thanks for reading Al
