I found this toe bone this weekend and am working on an ID. It is from Florida's Peace River, Pleistocene, and is 1.5" long.

I'm no expert so I would wait for a positive ID, but it looks similar to Smilodon Fatalis toe bone examples I have seen. Could be a whole lot of other things but I think you might be right about it being from a predator.

Very nice find! Yay! Looks much more robust than a Panther digit I have which is similar in length! Not a fair comparison without comparing same digit positions/species which I'm not smart enough to figure out..Looking forward to hearing/seeing what the more knowledgeable have to say.

Good luck with the ID confirmation. Continued hunting success!

Certainly, it appears to be a proximal phalanx from a big cat, which cat I cannot say.  Jaguars seem to be much more common than other possibilities.

I had failed to identify this bone beyond being a predator... My understanding of Felis phalanges is that there is a space for retractable claws:

As I look at Miatria's 2nd photo,  I now seem to see that space on her bone.

I have a small Jaguar phalanx at 1.25 inches, likely a female or juvenile.  I will go search for phalanx size range tables for possible felis predators in Florida.. It will help me understand who is next biggest in Florida feline predators...

These are proximal phalanges, Jack.  The off-set to accommodate the retractable claw is on the medial phalanx.

Well, that makes a lot more sense, and even explains a little because of a size factor between proximal and medial phalanges.

Thank you for the excellent charts and photos.  I'm saving them all to my computer.  I don't seem to have as much luck in my Google searches for good charts but I assume it's how I'm phrasing my query.

Jaguar and smilodon are both exciting possibilities.
