CrankyPongine Posted September 6 Author Share Posted September 6 It’s pretty distinct tho aren’t there possibilities of what it could be Link to comment Share on other sites More sharing options...
Jaybot Posted September 6 Share Posted September 6 This might be possible to ID down to bone type. At first glance my gut said a rib joint, however the more I look at it I’m thinkin’ maybe not. Perhaps some sort of toe bone or vertebra process? @Shellseeker, have you found anything like this? 1 -Jay “The earth doesn't need new continents, but new men.” ― Jules Verne, Twenty Thousand Leagues Under the Sea Link to comment Share on other sites More sharing options...
Fossildude19 Posted September 6 Share Posted September 6 Bone chunk that small, and weird looking, ... you'd have to be a pretty good anatomist to figure it out. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

Mahnmut Posted September 6 Share Posted September 6 Hi, I am not that anatomist, but I´d say weird looking could be a plus? @Harry Pristis maybe? Try to learn something about everything and everything about something Thomas Henry Huxley Link to comment Share on other sites More sharing options...

Jay, you are already suggesting the possibilities to investigate first... One key question is whether the bone is complete, basically unbroken... that would imply toebone...Giant tortoise, Rhino , Mastodon , and maybe sloth are all possibilities... Here is tortoise https://www.thefossilforum.com/topic/81460-winner-of-the-2017-vertebrate-find-of-the-year/ or https://www.thefossilforum.com/topic/126265-tooth-barb-bone/#comment-1371343 If there is a broken end, could be the broken off process halfway up the right lateral of this Alligator. Many animals have similar processes. 10 hours ago, CrankyPongine said: A bone fragment found on Venice or Caspersan beach, back in 2010. Dark brown in color. Broken end has pores. Mushroom shaped. Great photos for such a small bone: Broken ends do not have pores, If unbroken, high probability it is a toebone. I get a Sloth like feeling for the bone, but do not recognize it. This is the distinctive feature you would have to match by searching this forum and the Internet> I have done this many times. LOTS of effort, lots of time... Depends on how badly you want a specific identification. 2 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
CrankyPongine Posted September 6 Author Share Posted September 6 Thank you for all this! Are there any paleo mammalian specialists I could send photos of it to to find out more? Link to comment Share on other sites More sharing options...
CrankyPongine Posted September 6 Author Share Posted September 6 (edited) One of the ends does seem to show pores as if it was broken, specifically the side without the weird mushroom shape: first photo is it in hand with the non-mushroom side held up to the light. To the Alligator vertebrae ID, the part that would attach to the rest of the vertebra seems quite compressed compared to the photo you sent of it? So idk Edited September 6 by CrankyPongine Link to comment Share on other sites More sharing options...

CrankyPongine Posted September 6 Author Share Posted September 6 Found a thing on the toe bones of Paramylodon. One of the bones in the foot looks similar to this bone fragment. Link to comment Share on other sites More sharing options...

Shellseeker Posted September 6 Share Posted September 6 The process so far.. 1) You post a bone for Identification.. 2) No TFF members recognize the bone... This happens at least 30% of time. Not all members had a chance to see it, 3) So you get some possibilities and start searching TFF or the Internet. TFF has a great back history of fauna identifications, 4) You find some bone that looks the same like in this case ( a digit #2 medial phalanx for Paramylodon sloth. Congratulations !!!! 5) Using that knowledge you can now search the entire internet for other examples ! By the way, the most common sloth in the area you found this bone is Paramylodon harlani. You can send photos to the local university UF in Gainesville. Search for "University Florida fossil identification service" You will need at least 1 photo that looks like this.. Measurements in millemeters.. The university do not like a US penny for measurement value. I love sloth toe bones... and yours is different from any that I have seen. I am looking forward to what you are able to learn! 1 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

Though, given the two are closely related, and Paramylodon is native to Florida and the most common in the area I found the fragment in as Shellseeker said, I’ll stick with the Paramylodon harlani ID. (EDIT as of September 8th, 2024: No no, sorry again. Turns out the page shows both Mylodon AND Paramylodon, so the image DOES show Paramylodon) Edited September 9 by CrankyPongine Link to comment Share on other sites More sharing options...

As far as I know, there is not a "list" of Florida Ground Sloths species in one place but it is possible to get something close. Here is a start.. https://www.floridamuseum.ufl.edu/florida-vertebrate-fossils/species/eremotherium-eomigrans/ There were 3 Families of Sloths in Central_South Florida: 1) Eremotherium. 2 species. I have found less than 20 fossils, mostly claws and teeth. 2) Megalonyx 6 including Species Jefferson and Leptostomas and 3) Paramylodon 2 Species Harlani and Garbani. For all intents and purposes , your photo is Paramylodon harlani, the dominate Mylodon family species in Florida. Search TFF or Wikipedia or the open Internet for the names in the above sentence, you should be able to create such a list within a week. Identifications are never certain, but I would say the likelihood in this case is over 90%. We will see what the UF Fossil Identification service will respond. They have the experts on Florida Fossil Solths.

CrankyPongine Posted September 8 Author Share Posted September 8 Yeah I looked at the foot of an Eremotherium before and it doesn’t seem to have any bones that resemble this one and is shaped completely different. 1 Link to comment Share on other sites More sharing options...
