Bargain, Unprepared Fossil Fish (Priscacara) - 4" Long

This is an unprepared Priscacara serrata collected from the 18 inch layer of the Green River Formation near Kemmerer, Wyoming. It appears to be around 4 inches in length, and is hanging off of the edge, hence the reduced price. It's on a rectangularly cut 6.6x3.4 slab of shale which is about .5" thick.

The fish from the 18 layers of the Green River Formation, has a very dark and detailed preservation. They split out entirely under the surface of the rock, typically with only raised relief from the backbone as an indication that there is a fish. This layer is typically collected at night under spotlight, allowing for the shadows from the raised relief to be seen more easily.

Aside from the fish hanging off the edge of the plate, it looks well articulated, though there is some disarticulation of the tail. The rock on this particular plate is fairly hard so an air scribe is highly recommended to prepare it.

Here is an example of prepared Diplomystus from the 18 inch layer.
