Here's another one for the catfish fans. This is an unfortunate small shoal of Astephus antiquus cats that died together from some geologic event (mudslide, volcano, etc.) They're from the Eocene deposits of the Green River Basin in Wyoming.

Here's a brain-buster for you. It's believed that only one in a million of a species dies in such a way that permits the fossilization process to occur. Of those, only one in a million fossilize as an intact articulated specimen. Keeping those numbers in mind, how rare do you think this fossil is?

This is Mioplosus labracoides in an asphyxiation display, He choked on a Diplomystus dentatus that was too big to swallow or spit out. They're from the Eocene of the Green River Basin Formation in Wyoming.

Oh my god Oddball! How do you get these? I've always wanted to find fossils of ancient animals, that would be awesome.

Nice pieces. I'm not really up on non-dino or non-fish fossils. However, the 1st specimen is a fossil fern called Neuropterus sp. from the Mazon Creek formation of Braidwood, IL (I collected these when I was stationed at GLakes Navy Training cntr). The next is a crinoid or fossil sea-lily (echinoderm) called Pentacrinites sp. 3rd piece is a trilobite called Elrathia kingi from Antelope Springs in Delta, Utah. Last piece is an ammonite (like a chambered nautilus). The concretion looks like several I collected in England.
