hugolee Posted March 19, 2017 Share Posted March 19, 2017 Hi there! I found this specimen on a beach in north Florida (Amelia Island). The curve shape caught my eye, and the black surface changing to dark brown interior reminded me of fossil coloration. Any chance this is a fossilized tusk of some kind? Hopefully the photos are detailed enough. Many thanks! Link to comment Share on other sites More sharing options...
Peat Burns Posted March 19, 2017 Share Posted March 19, 2017 This to me resembles a piece of dugong rib. It looks very dense, and I think I see the typical rings in cross section. Let's see what others have to say. EDIT: Upon further observation, I think it might be a bit too porous to be dugong rib?... Link to comment Share on other sites More sharing options...
Peat Burns Posted March 19, 2017 Share Posted March 19, 2017 It may be that some areas of dugong rib exhibit porous character (all of my chunks are extremely dense and lack obvious pores). Here is a thread and photo of another members find with similar characteristics to yours. Link to comment Share on other sites More sharing options...

hugolee Posted March 25, 2017 Author Share Posted March 25, 2017 Had never heard of a dugong! Very cool. Thanks for the quick feedback, everyone. Any sense of how old it might be? Link to comment Share on other sites More sharing options...
Monica Posted March 25, 2017 Share Posted March 25, 2017 Hi hugolee! I have no idea as to the age of your fossil, but dugongs are still around today! They are sometimes called "sea cows" and I think they live in the Pacific and Indian Oceans. Nice find! Monica Link to comment Share on other sites More sharing options...

Manatees are primarily saltwater denizens. They retreat to freshwater springs in Florida for warmth in the winter.

I think I recall that dugongs are found around Australia while manatees are found around Florida - I believe they are different species of the same family...

You are right about the range of the extant dugong. It looks like manatees are a different family, though (same order). Link to comment Share on other sites More sharing options...

fifbrindacier Posted March 26, 2017 Share Posted March 26, 2017 The manatees (lamantin in french) are Sireniae Trichechidae found in Senegal, Carribean, Florida, Central America and Amazonia. Dugongs are Sireniae Dugongidae and live in west Pacific Ocean and Indian Ocean. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."
