Here's a cool one from California. This is a mortality plate (multiple similar species) with several Syngnathus acus pipefish from the pliocene period.

Here's another mortality plate. These little fish come with a big name. These are Gosiutichthys parvus. An interesting note to this piece concerns the gray patch to the left. That's what remains of the volcanic ash layer that I removed to expose the fish against the normal silt (tan) layer they're lying on. A mud slide of ash covered and asphyxiated these fish 50 million years ago.
The close up pic is of a Knightia that died amongst the Gosiutichthys.

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.

5 Procharcharodon megalodon teeth. This is the great white that grew to 80 feet. That's 2 school buses end to end, boys and girls. The center tooth is from Chile and the rest from various rivers in Florida. All are Miocene.

And, we need a principle predator for this batch. Here's a juvenile Cladocyclus ferus. I need to dig out the 4 footer I have somewhere. This line died out. But, doesn't the head look arowana-ish? I first thought 'viperfish' but, this species lacks the tusks.
