Tony G. Posted October 14, 2022 Share Posted October 14, 2022 I collect armadillo fossils. All of my fossils have been purchased and I have been able to identify most of them using the internet. The attached photos are from bones I purchased labeled Holmesina carpals. Both seem to be the same bone, one from holmesina septentrionalis and one from holmesina floridanus (my guess). They are both river finds from Northern Florida, USA. I have not been able to find a photo or diagram showing this bone. Does anyone have a photo or diagram showing this bones position in the skeleton. If these bones are not from the Holmesina genus, I would like to know that also. 2 Link to comment Share on other sites More sharing options...

Harry Pristis Posted October 14, 2022 Share Posted October 14, 2022 How unusual! I don't recognize these as armadillo bones, which are MOL recognizable as homologs of the bones of other mammals.

I have hunted SW Florida for 15 years. It has lots of Armadillo fossils. Hard to go hunting without finding one. Like, Harry, I have never seen this bone previously. We have a fossil identification Service in Florida: If you submit, some of the experts at UF will try to identify. @digit https://www.floridamuseum.ufl.edu/vertpaleo/amateur-collector/fossil-id/ 4 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 October 15, 2022 Share Posted October 15, 2022 I have little confidence, but I do have a nagging suspicion that this is a 'gator skull bone. Disarticulated, the 'gator skull has 53 separate bones. 5 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...
Brandy Cole Posted October 15, 2022 Share Posted October 15, 2022 It looks similar to a calcaneus to me, but I can't tell what from. 1 Link to comment Share on other sites More sharing options...
Brandy Cole Posted October 15, 2022 Share Posted October 15, 2022 @Tony G. Can you give us pictures with a few more angles? Link to comment Share on other sites More sharing options...
digit Posted October 15, 2022 Share Posted October 15, 2022 I agree that the articulating surfaces do look much more like a calcaneum than a carpal. The link that Jack gave above is good and has the updated email address for fossil ID: vertpaleo@floridamuseum.ufl.edu Due to Richard Hulbert's retirement, this email address is being monitored by several FLMNH staff--one of which specializes in xenarthran fossils and she would instantly recognize this if it were part of any Holmesina species. Cheers. -Ken 2 Link to comment Share on other sites More sharing options...

Tony G. Posted October 17, 2022 Author Share Posted October 17, 2022 (edited) I think this may be the navicular bone. I have 2 known calcaneum bones from Holmesina and an astragalus bone. The astragalus I have was not the correct side, but I had made a 3d model of it on my computer and inverted it to be the other side. When I put the calcaneum and the astragalus 3d print together, this bone fits fairly well up against them. It maybe just slightly off in size for a perfet fit. I will add picture later today. Found this last night.

NICE !!!! I love understanding the thought sequence, the processes and resources you use to narrow down a possibility !!! I suppose it does help to have an extensive Holmesina bone collection. 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...
Tony G. Posted October 17, 2022 Author Share Posted October 17, 2022 (edited) Used some of my wifes hair ties to hold it all together, but I'm pretty sure this is how it fits together. Edited October 17, 2022 by Tony G. added photo 1 Link to comment Share on other sites More sharing options...
