Tigereagle12345 Posted April 27, 2022 Share Posted April 27, 2022 I recently finished preparing a fish fossil from the Green River formation that I purchased online. The site said that the fossil would be either a Knighta or a Diplomystus. From looking at images, the face seemed to look like a Diplomystus but the body seemed more like Knighta. Could anyone tell me which it is? Thanks in advance, Tigereagle12345 Measurements are 11.5 cm by 2.5 cm Link to comment Share on other sites More sharing options...
Nanotyrannus35 Posted April 27, 2022 Share Posted April 27, 2022 Good job on the prep and that's a knightia. 2 Enthusiastic Fossil Hunter Link to comment Share on other sites More sharing options...

Fossildude19 Posted April 27, 2022 Share Posted April 27, 2022 Yup. Knightia eocaena. A Diplomystus has a longer anal fin, thickened post cranial bones dorsally, thicker scales anterior to the dorsal fin, a deeper v shape to the tail, and pectoral fins located higher up on the body.
