Jake alexander Posted March 20, 2017 Share Posted March 20, 2017 My father had found this bone about 2 years back, we think it is a dugong or manatee bone. It was found in Venice, Florida. Thanks to anyone who can identify. Link to comment Share on other sites More sharing options...

FossilDudeCO Posted March 20, 2017 Share Posted March 20, 2017 yup, would appear to be a dugong rib section. Link to comment Share on other sites More sharing options...
Fishconner10 Posted March 20, 2017 Share Posted March 20, 2017 Definitely dugong Link to comment Share on other sites More sharing options...
Ptychodus04 Posted March 20, 2017 Share Posted March 20, 2017 I'm not seeing any bone texture in the photos. Looks more like a chert nodule to me. Can someone educate me on why it's definitely dugong?

Can someone educate me on why it's definitely dugong? Dugong ribs are really dense and tend not to show cancellous bone texture. They do usually exhibit some faint eccentric growth rings in cross section. River worn ones are often glossy. Florida river specimens are usually chocolate brown in color, often with clam borings. I can't see enough from these photos to be 100% sure (cross section is blurry), but it has some characteristics. Link to comment Share on other sites More sharing options...

Peat Burns Posted March 20, 2017 Share Posted March 20, 2017 Just now, Ptychodus04 said: That is helpful. Thanks. No problem. I was skeptical when someone showed me one for the first time. I thought it was an iron-rich concretion or something. I ended up cutting it and sanding the end and saw the growth rings and compared to photos of ones taken from skeletons. Very interesting / unusual... Link to comment Share on other sites More sharing options...
