Shellseeker Posted June 22, 2020 Share Posted June 22, 2020 Fossilized 1/2 bone, 4.5 inches, Seems to be a humerus. Searching the internet, I came across this photo of a much larger complete humerus.

Harry Pristis Posted June 22, 2020 Share Posted June 22, 2020 Sure, dugongid or trichechid. Here are some more images of my dugongid humerus (which is considerably larger than average). The first image shows an average-size partial (the left side): 3 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...
Shellseeker Posted June 22, 2020 Author Share Posted June 22, 2020 Thanks, @Harry Pristis I was slightly put off by the obvious difference in size between my find and your photo. Also we had not previously found any other dugongid or trichechid fossils (ribs, bones, teeth) in this location. I had looked at Teleoceras humerous, which is huge compared to my find, but oddly enough is somewhat similar to dugong.

Boesse Posted June 22, 2020 Share Posted June 22, 2020 I agree with sirenian humerus - it is quite tiny, though. A smallish species of Metaxytherium, Crenatosiren, or perhaps Nanosiren are all possibilities; second one is Metaxytherium albifontanum - both this and Crenatosiren are Oligocene taxa. 2 Link to comment Share on other sites More sharing options...

I had been speculating that this location was mid_miocene consistent with the ages of the Central Florida Phosphate mines (?? 13-15 mya) based on other fauna fossils found and identified. But I am always open to new ideas.
