Calvin Jenkins Posted March 21, 2017 Share Posted March 21, 2017 Found this today in slough adjoining Myakka river. It is round but straight, about 2" long and nearly 1/2" in diameter. I did find a dolphin tooth and several small (<1") shark teeth plus smaller bone fragments (area has larger mammal fragments nearby. Education appreciated!

digit Posted March 21, 2017 Share Posted March 21, 2017 Additional photos would be helpful (from other angles). From this one image I'm leaning toward a bone fragment. The "wrinkles" (cracks) along the length are what is triggering that in my mind. EDIT: Tony and I in a photo finish on that reply. Cheers. -Ken 1 Link to comment Share on other sites More sharing options...
Calvin Jenkins Posted March 21, 2017 Author Share Posted March 21, 2017 More photos, so could this be a dugong rib bone? I'll compare to some of my bigger bones to see if I have the similar cracking pattern. Thanks, Calvin Link to comment Share on other sites More sharing options...
ynot Posted March 21, 2017 Share Posted March 21, 2017 I would go along with a dugong rib fragment. Darwin said: " Man sprang from monkeys."

Calvin Jenkins Posted March 21, 2017 Author Share Posted March 21, 2017 So what does the cracking pattern along the length indicate? I looked at my other bits of Dugong/whale bones & these are smooth with no external cracks. Is it related to not being under water all year? Thanks, Calvin Link to comment Share on other sites More sharing options...
ynot Posted March 21, 2017 Share Posted March 21, 2017 Bone will often crack longitudinally when it drys out. My guess is it happened before fossilizing. Wait for the Florida collectors to confirm the id though, as I have never seen a dugong rib in person. 1 Darwin said: " Man sprang from monkeys."

calhounensis Posted March 22, 2017 Share Posted March 22, 2017 My first impression is that this is a beat up whale tooth. The more I look, the less confident I am on that. Link to comment Share on other sites More sharing options...

The more I look, the less confident I am on that. This was my first impression as well. In the first picture i see a clear layer of what looks to be enamel and possibly even a hint of a nerve cavity in the broken portion. I've never seen such a color contrast of layering in Dugong ribs before. If not Whale, possibly tusk (walrus, peccary)??? ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...

doushantuo Posted March 22, 2017 Share Posted March 22, 2017 a short remark on dugong ribs: "The first rib is more or less straight and cylindrical; from the second onwards, the ribs are curved -- the 2nd to 4th ribs are compressed while the rest are cylindrical. The tips of the anterior 12 pairs of ribs are truncate, those of the last 6 pairs pointed. From the 5th rib onwards, a protuberance is present at about the mid-length of the rib. These protuberances, which are directed backwards, are more conspicuous on the 14th, 15th, and 18th pairs of ribs.'' Source: James,1974 1 Link to comment Share on other sites More sharing options...
Calvin Jenkins Posted March 22, 2017 Author Share Posted March 22, 2017 So I did a bit more research on this too, here in FL we see bunches of dugong bones, which is a good harbinger but very un-exciting so it usually gets tossed aside (makes for good plant bedding material!). What I found is there are two different styles of dugong bone structures... "Big Boned" as seen here... https://commons.wikimedia.org/wiki/File:Hydrodamalis_gigas_skeleton_-_Finnish_Museum_of_Natural_History_-_DSC04529.JPG and "Skinny Boned" as seen here.... https://commons.wikimedia.org/wiki/File:Dugong_dugon_(skeleton)_at_Göteborgs_Naturhistoriska_Museum_7976.jpg Usually what I encounter in SW FL appears to be the rib bones of the "Big Boned" variety but I can see how a Skinny boned version would match the item found above. Unfortunately I'm not well versed enough in Dugong to know if the skinny grows into the big boned or if they are different species or eras.

fossilized6s Posted March 23, 2017 Share Posted March 23, 2017 Hopefully @Harry PristisPristis will chime in with his opinions before you hurl it into the yard.

Harry Pristis Posted March 23, 2017 Share Posted March 23, 2017 Nothing novel here . . . it appears to me to be what's left of a whale tooth. 1 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...
sixgill pete Posted March 23, 2017 Share Posted March 23, 2017 I agree with a rather well worn whale tooth.

Boesse Posted March 23, 2017 Share Posted March 23, 2017 Looks cetacean to me. But, it is not preserved very well and I'm unable to identify it further than Odontoceti indet. Link to comment Share on other sites More sharing options...
