DUGONG (Manatee), Whale, ... or Fossil Corals ???

Recommended Posts

LONGOF

I have been found relatively abundant fossil remains of what I think can be dugong (manatee) ribs and other related bones (?), in the Caribbean.  Mostly end on pointed-ends.  I have heard about the burial social preferences of manatees also.  They are relatively common but any skull has been found yet.

 

Can you help me to ID these bone-like fossils??  How to differenciate it even from fossil whales.  Thanks deeply for all your help adorable Community !!

Welcome to :tff: !

I think these look more like trace fossils than bone. Can You post pictures of the ends of the pieces?

I agree with Tony.

Welcome to the forum! I agree, most likely a burrow. What drew my eye was the fossil/suggestive rock indicated by the red arrow? Did you happen to collect this?

Not yet Lori, but please take in account that I have found hundreds of these bone-like/rib-like fossils. as burial settlements.  Please take a look on the other pictures, where pieces end as narrow ends, like ribs.  They are very solid also.  Thanks for your help Lori and all collegaues!!  Your experienced wonderful and very valuable help is very useful for all of us!

None of them look like bone to me, but as Tony said, we would need to see an end view to verify. I am not a bone expert, but the rib bones I have found have an oval shape when look from the end, and really didn't taper like that. Also, long pieces would have a slight curve. From the views shown, I can't make out any surface texture that would indicate bone. The last photo you posted looks like it could be a root cast of some sort. Again, not really my area of expertise. Very interesting!

I agree with the others.
This kind of abundance and forms are typical to an ichnofacies. Sometimes, trace fossil burrows can be very large, long, curved, serpulating, branched or not, etc. Here is a partially specimen of mine, recovered from sandy sandstone Miocene sediments from Romania :

Thanks to all of you colleagues, but our findings are not curved.  The also have up to 6-8 inches width and they're relatively solid.  Thanks for all your ID fossil helps !

Interesting finds..

By any chance do any of the specimens show a freshly fractured or perhaps a non-weathered or clean/polished end that could show us the internal structure? We pick up alot of dugong and an occasional whale rib piece here in Florida and while much of it is very dense and wont show any real cellular/porous grainy texture, occasionally I do see some of the banding in the dugong material.  Right now I'm inclined to say what you have are traces of something else/casts...That first photo with the elongated specimen above the rock pick particularly makes me wonder...The structure below the rock pick looks more geologic like the mixes of limestone/marl/chert we have in some of the Ocala formation outcrops. By any chance do you know what formation you are finding these things in? Might be interesting to look into what the geologic map and pubs on the area describe about the rocks/geology of what you are finding these in.  

 

Thanks for the photos...good stuff...

I goofed and didnt get to add photos of some examples of unidentified bone showing internal/exterior textures/probable dugong from FLorida
