Not exactly sure whether this is new information, has already been observed, or if this is just me misinterpreting fossils, but I recently noticed that there are two species of the Coon Creek Formation that look very similar. That being Pterotrigonia thoracica and Trigonia eufaulensis. I noticed while observing a gallery made by @Herb that each species looks very similar, and are almost indistinguishable.

Greetings Guys! I found this many years ago while on vacation in San Antonio Texas.
