Swimming Creek Find

[ConnorR]

A year or two ago I visited a swimming creek in Oklahoma with family (I can't tell you which one for the life of me). The first thing I did after stepping out of the SUV was pick up what looked like an impression fossil off of the ground (the shoreline of the creek was all pebbles). It must have been sheer luck, because I couldn't find anything else the whole time I was there. My guess is that it's a chrinoid stem. Am I close?

Yes, it is the external mold of a crinoid stem.

 

At the bottom of the below web page, go look at:

 

"Crinoids: Melocrinus williamsi (PRI 76743) by Digital Atlas of Ancient Life on Sketchfab

Fossil specimens of the crinoid Melocrinus williamsi from the Devonian Ithaca Formation

of Cortland County, New York. Specimen is from the collections of the Paleontological

Research Institution, Ithaca, New York."

 

Yours,
