Brett Breakin' Rocks Posted June 12, 2018 Share Posted June 12, 2018 Hello Everyone, My treks to the river total 3 now and it is definitely a hit or miss sort of journey. This is a very worn phalanx of some sort ? Sloth possibly ... ? I'm not sure it's just a wild guess based on what I have seen before and online. @Harry Pristis @Shellseeker My mammal id's are not comparable to those of my South Florida fossil hunter masters. I apologize ahead of time these images are not my usual standard. The bones were in a fresh water soak and were still drying .... Size: 3 inches Long -- 1.5 inches wide Thanks, Brett 1 Link to comment Share on other sites More sharing options...
Shellseeker Posted June 12, 2018 Share Posted June 12, 2018 Brett, I love sloth. This one is a Sloth Medial phalanx.. http://www.thefossilforum.com/index.php?/gallery/image/10353-small-sloth-medial-phalanx/ WoW I just got a message that I did not have permission to see the contents of this link, but I found/viewed it on the open internet.

So, do you think this is a sloth phalanx .. it looks the part right ? Not sure where it lies in the back or front of the animal. Thanks again, Brett Link to comment Share on other sites More sharing options...

Thanks again, Brett Cris has a great photo of the claw connected to the Medial Phalanx, which you have found here, connected to a proximal phalanx, which I tend to find. Here is a large proximal that I found 2-3 weeks ago and have not sorted/catalogued yet. 2 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

I am amazed that they have survived so long being beat up and dragged from one location to the next over the millennia. This one that I have has a hole in it ... and the fossil has been hollowed out leaving a shell of what once was. Thanks again for the examples guys.

We get quite a few locals here on FB that post images that are positively identified and I am saving these with the associated usernames that I can use in the future. The internet is an amazing tool for our amateur endeavors. Speaking of Medial Phalanx ... hopefully this isn't an awful thing to ride on the ID of another. This looks like a phalanx of an adult mammoth .. as opposed to the smaller one I found in Summerville. It's banged up a bit but some of the surface texture remains. I was surprised it survived the dredge. Most of what I find is indecipherable chunks ... that I admire from a distance. Cheers, B Link to comment Share on other sites More sharing options...

Shellseeker Posted June 12, 2018 Share Posted June 12, 2018 2 hours ago, Harry Pristis said: For comparison: @Harry Pristis, Sorry to keep pulling you back into this, but I just realized something for the 1st time. I was cleaning and photographing the above Sloth Proximal Phalanx prior to identification and storage. This bone has serious muscle attachment scars on one side, not the other, which means whether this bone was on the left or right side of the animal is determined. Thinking of my human digits, I think that this bone came from a right side appendage. Is this correct, and if so, can one differentiate between an "arm" and "foot" based on more extensive muscle scaring on the "arm" due to use? Also , does similar asymmetric muscle attachment scaring occur on other mammal finger and toe digits? Thanks for any insights. jack The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
Harry Pristis Posted June 12, 2018 Share Posted June 12, 2018 I dunno, Jack. I've never paid a lot of attention to muscle attachments on these bones except how they may fit putative matches. I find it easier to find fits starting with the claw. The pedal clawsl are straight, while the claws of the manus are hooked. 2 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

Thanks, Harry I was/am about to step off and search for the answer(s) to my questions and sometimes (maybe many times) you have already done the work and know the answers and saw some reference in a paper or book. I'll try to go after this one and feedback anything I find. Looking at one of @Fruitbat references, I found this. My Proximal Phalanx is from Megalonyx Jeffersonii, IV digit. The one in the picture above is 62.3 mm, mine is 63.5 - close enough. It seems that you have a couple in your boxes, 1st box lower right; 2nd box upper left. Curiosity on whether the one inlower right 1st box has any obvious muscle attachment difference. I'll work the internet and Fruitbat's library and then likely send a note to Hulbert. Thanks for your response. This was news to me: Quote The pedal claws are straight, while the claws of the manus are hooked.
