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 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
darrow Posted November 2, 2017 Author Share Posted November 2, 2017 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. Darrow Shellseaker it looks like your's in missing the sheath. 1 Link to comment Share on other sites More sharing options...

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 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

darrow Posted November 2, 2017 Author Share Posted November 2, 2017 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 Quote above and illustration below from...

darrow Posted November 2, 2017 Author Share Posted November 2, 2017 Some quick views of the ventral tuberosity, articular concavities, nutrient foramin, and partial "sheath" with missing section drawn in red.
