Awesome find! I have a large collection from the peace river (where I often hunt)  Ones of those, still eludes me!  Great find!

FANTASTIC FIND :yay-smiley-1::yay-smiley-1: Congratulations. You must feel on top of the world!.  I love the veins for blood vessels that are clearly differentiated. Please provide other views as you get the time. I am interested in identification.  :popcorn: Which sloths are prevalent in Texas fossil record?

Wow, excellent find.... finally got my first just this past spring :fistbump: it had been on my list a while

Every once in a great while it's not just a big rock down there!

That, sir, is a coveted Texas find.

Yes! Welcome to the club! That looks like a nice one. I think megalonyx jeffersoni is prevalent here. Eremothere may have been around but this claw looks a little small for that beast.

Thanks for the response.  I have been fighting a virus and slow to respond.  Here is a jeffersoni that I found in Florida. 

Note the complex "attachment" end... On Darrow's find, very different and I was curious about why. Different claw position, different species.... etc

Perhaps not very evident in my original photos but the proximal end of the claw core is damaged...  broken off approximately at the red line below.

I'll take some clear pictures multiple views and post them in the ID section later this week.  In the meantime if anyone can point me to a diagnostic dimensional study that might help identify species or genus I'd appreciate it.  I've not found much beyond terms like " more curved" or "laterally flattened" which aren't really very helpful.

Shellseaker it looks like your's in missing the sheath.

Darrow,

Thanks for the update,  I have actually seen sloth claws that have less curved proximal ends. Also I have found 5 sloth claws, none of which have any vestige of a sheath.. I have found 3 Jeffersons, 1 Harlan, and 1 very small Megalonyx leptostomus

It is very rare for keratin to fossilize, so no claw sheaths.

Yes, of course I wasn't referring to the keratin nail itself...    the "sheath" being the boney pocket at the proximal end that supports the base of the keratin nail or claw and from which the keratin grows in life.   Although from personal experience I'd expect keratin in fact originates from the entire surface claw core including from within the "pocket". 

"In life the bony core would have been covered with a toenail growing out of the pocket or sheath at the wide end." http://slothcentral.com/archives/2505

Some quick views of the ventral tuberosity, articular concavities, nutrient foramin, and partial "sheath" with missing section drawn in red.  You can also see where the dorsal process is broken off my example...

Did not know that, Thanks.

Fantastic find! Would make for a great Fossil of the Month! Can it still be applied for November even though found so late in October?

If the majority of the prep is done in the month in which it is entered, it would be eligible. :)

I would love to find one of those, especially for my wife.  She is a zookeeper and have two sloths where she works at.
