There's a reason collector's love the Green River Formation of Wyoming. The fish there never go bad even after 50 million years! Cracking open some limestone and catching an Eocene fish is such a treat. This one is probably a fragment of Priscacara.

Angustidens shark tooth from the Bone Valley Formation of Florida.
My find of the day last Friday. About 5% of the blade was showing above ground, and I pulled it out by that. The circle in the picture is where the remains of the cusp are located.

"I am a lifelong collector of anything that I find interesting, as long as it's something on, or in, the ground. This particular item was found while walking in a stream looking for Upper Pennsylvanian, Carboniferous Fossils. I don't actually have to look that hard, It's the carrying out, and finding storage room." —Mark

[OK, fossil collectors, it can sometimes be hard to tell when you find a unexpected tooth in a stream. Is this a modern mammal or a Pleistocene mammal fossil that washed into the stream from above the Carboniferous layers? Please leave a response.]
