The "big guy" to find at POC. Though, this one is smaller, the preservation is as good as it gets for this location. In fact, it makes me believe that POC could draw from layers adjacent to the Eagle Ford Group. I've found matrix pieces that are consistent with the geology of EFG, but need to find matrix pieces with this kind of preservation to confirm Atco or something else. I'm also not sure that this is C. crassidens anymore since this smaller, narrower form differs so much from the holotype. I currently believe it's an undescribed species since I haven't found something that ma -

To find denticles, you need to go to the finest grain size. This beautiful one could be shark, but I'm not certain.-

Rhinobatos teeth are probably the smallest teeth you can hope to find here - they are about as small as grains of sand.-
