  1. Hello - Is this a whale rib bone? Maybe a Dugong rib bone? Came out of Florida near Venice. Thank you.
  2. I found this tooth a while back in a small private agricultural marl pit I have been hunting for a few years. It is Eocene Castle Hayne Formation in eastern North Carolina. This pit has produced roughly 26 species of Eocene sharks, including multiple Hexanchus, C. auricualtus up to 3 1/2 inches; sea snake verts, large amounts of Pristis fossils among other items. It also has yielded multiple archaeocete whale teeth and verts. I originally thought this was a small whale tooth, but it just didnt seem right to call it whale. In Oct. at the annual NCFC Fossil Fair in Hickory N.C. I had it on display. Retired Smithsonian Paleontologist Dave Bohaska said he thought it was "sea cow" He took multiple pics of it, but I am still awaiting his replies. I have been doing some research on line when I came upon this archived thread. What do you guys think? @siteseer @Boesse Adding pics in next post

    A rare find

    Out today with a good friend. It seemed to be his day 5 Horse Teeth, a Bison Astragalus, and 3 decent Megs...On the 1st sieve, I found an incisor and an hour later a small predator astragalus. The rest of my day was mostly small shark teeth until the very end. We went to a spot where we had super success for a couple of years and coming back first time this season.. It has 6 or 8 feet of large fossil producing gravel, but 4 feet of sand had rolled over that gravel and added about 4 inches of new gravel on top of the stand but that gravel contained few fossils beside those small teeth... Here is the incisor... I think it is Llama, but very small. Could it be wild pig? and the Predator astragalus... Harry identified a very similar one as Raccoon 2 years back, and finally the star of my day, This is a Miocene fossil (7-14 mya) and Rare !! Only my 5th in 15 years . A great reward for my efforts today... A high quality tooth, barely erupted...
  4. I found these four vertebra in Gainesville creeks and I am wondering what is the best way to go about identifying them? Any tips? I assume they are generally whale/dugong/porpoise

    Protosirenian?

    Please help. Are these occipitals of a Protosiren? They were collected from the Crystal River in Ocala by a diver. I've had them for years. Now I'm wondering if I'm lucky enough to have two specimens of a super rare sirenian.

    Vertebra, Dugong or Manatee

    Went out yesterday.. Peace river is still the color of Pea Soup, and is at least a foot higher. I had some finds that I did not recognize, and decided to break these 2 out.. On Monday, partner tossed me a broken bone.I can find no break except leading down from 1st and 2nd photos. My partner called it a Dugong Vert process. I have searched both Dugong and Manatee Vertebrae without finding a match. We returned to this location yesterday. I found another bone, which my partner referred to as a "Topknot" for a Dugong Vertebra. Comparative bone is from the UFMNH website. Note that nothing quite matched the May 22nd find.. Thanks for the help , Jack

    ID help, please and thanks!

    Almost everything was found yesterday at Peace River (FL). I’m still new to fossil hunting. I do my research but still need help - there’s a lot to learn. TIA for anyone who takes the time to let me know what I’ve got here! In order, I think I have: -Deer ankle bone -Scapula? Turtle shell? -Glyptodont scutes -Horse/camel incisor? -Manatee/dugong tooth? -Shells (I know nothing about these but love these two-wanted to share) -Gator/plant? Pattern is only on one side -Deer tooth? -Camel/deer tooth? -Stumped - too many teeth look too similar…tapir? -Recent shark tooth finds (contents of the final picture were found on land in Sarasota county and not at the river) I think that’s more than enough for now I have quite a few horse/bison/camel/llama/etc teeth that I also need help differentiating, but I want to try a little more before asking for help. Any good charts/info that help point out differences in these would be greatly appreciated! Adding some pics of recent shark tooth finds just for the fun of sharing. If you see anything special (rare/pathos/etc) that I need to know about, please let me know! Again, thanks in advance for all the help! Any ideas appreciated - if better pics/measurements are needed, just ask

    Bone? Dugong?

    Found this rock.bone in Venice, FL. It strikes me as organic but the top portion I expect to be a socket of sorts seems like a mess for a bone. Any ideas? Approx 4 in long by 2 in long at the “socket”
  9. Another day hunting with a friend. Having a friend along manages to give me a sense of security during the Florida alligator mating season. It makes no sense for an alligator to mistake me for a potential mate, but I am wearing a black wetsuit. In any case , we have found a productive hunting site that seems to improve as time goes by. I has lots of opportunity to pick items out of my screen. There are some interesting fossils that I am not doing close_up photos on: Horse earbone in upper left, Gator Osteoderm, center top, I reacted when that blue triangle fell into my screen, I thought it was a gift from some ancient humans, but no such luck... this time. There is a little of white druzy covering a silica shell fragment, some nice long sea urchin spines, a bunch of turtle footpads, a deer ungual and antler frag, a 42 mm Meg and lots and lots of shark teeth, including a couple of tiny threshers, one nurse shark tooth, and some of the smallest Snaggletooth upper teeth I have found. Here are some of the finds I think I recognize, but always willing to be corrected. 1) A Glyptodon Osteoderm from the edge of the carapace. (3 broken sides) 2) Another Glyptodon Osteoderm from the edge of the carapace. This one only has 2 broken sides... unusual 3) A Dugong Vertebra process fragment in fantastic shape.... This is 3 plus mya.. look at the lack of wear... small lines on the bone. 4) A Camel Unciform (ankle bone)... that is slightly broken off to the right I set that thread up as a "fossil ID", but I recognize more of what I found. 5) An enamel "cap", no roots... an in_process tooth which is pretty rare in/of itself from the lower jaw of a juvenile tapir and (did I say enamel caps are rare?) 6) An enamel "cap", no roots but in this case much rarer because the animal is much rarer than tapir. Metaxytherium floridanum, the Florida dugong lived 14-7 myas ago. I have found less than 10 of these over 15 years of hunting. Now down to the Fossil ID part of this thread , one I am not sure of... and hope that @Harry Pristis has some insights 7) It seems to be a tooth L 22, Height 8, W 5 mm. I wonder which is the root end and which is the chewing end. and the last, I have never seen before and while it could be a fossil, I am unsure if it is mammal or fish. 8) 31 x 13 mm. All comments and suggestions appreciated. I am wondering of there is a seashell or bottle cap inside. It is an ongoing joy to have such a variety of fossils to find and 15 years of hunting still be unsure of exactly what I am finding. Jack

    Mammal identification

    Today we went to a spot that we don't go often, it started raining about 50 minutes in (we should have checked the weather) but we got quite a few fossils including these unidentified ones (sorry about the picture quality on some of them) the first I believe is a gator tooth with root, the second set, I have no idea about, the 3rd might be dugong, the forth and 5th I think are deer, the sixth I think is tapir, the seventh Is some sort of rodent and the last I believe is a snake vert.
  11. Hey guys, I have a special creek site close to me in South Florida. it yields marine fossils of every kind and even some artifacts. I have found many pieces of dugong bone with a strange circular indentation, and I’m really hoping someone can help me out with determining what causes this? I have found fossils of a huge variety of Pliocene/Miocene marine animals, and dugong bones are the only bones with such markings. There is a raised center and an almost perfect circular depression around it.
  12. Made my first fossil hunting trip to South Carolina, went to some areas around Summerville, thought I’d share pics of some of the fossils I collected! The best finds were some echovenator-like teeth, Angies, great whites, some intact sections of dugong ribs, and several associated pieces of a sea turtle shell. Felt like Indiana Jones exploring all the creeks trying to find productive spots haha. Fun trip, hope to return in the future!
  13. Greetings from Inland Venice, FL. Unusual fossil find for me. Pleistocene material. My first thought was Dugong when I picked it up, and fit great into my hand. I have found hundreds of Dugong ribs in the last year at my location. This is an unusual one due to the smooth texture. It measures 4.5 inches long by 2 inches wide. Density is 2.51 g/cm3 if you are interested. Photo labeled "4" shows odd texture. Closeup attached. FYI: Indian artifacts confirmed to 10,000 B.C. recovered within 10 miles. I have not previously recovered any Indian artifacts. I'm looking for feedback. Thanks in advance friends. -Michael
  14. Hey all, Thought I would share this blog post that has a comprehensive review of all papers in marine mammal paleontology published in 2020. Enjoy! https://coastalpaleo.blogspot.com/2020/12/2020-in-review-advances-in-marine.html

    Sirenia.jpg

    I 3d-printed some skull-replicas of 3 sirenia genera: West Indian Manatee (Trichechus manatus) Padific Dugong (Dugong dugon) and Steller's Sea-cow (Hydrodamalis gigas). I was really amazed about the fact that, despite the immense disparity in body-size between the extinct sea-cow and its extant relatives, their heads/crania were remarkably similar to each other in overall dimensions. The sea-cow skull was larger, but not by as much as one would think.
  16. Hello, I'm a newbie. I'm looking for advice on what product to place on the fossils in the boulder below. I want to stabilize them in the matrix before I do any more removal. The photo with the (5) had a great rib in it but crumbled upon getting the rock into my truck. Fossils are exposed on many sides. As I began removing matrix with my Dremel 290, more fossils were uncovered. I read many articles and posts about solution adhesives. I want to keep it simple. I found premade Paraloid B-72 Glue, and the more complicated acetone and b-72, b-76 pellets. I may try and use a filler on my rib (1) that has a crack. This has been a great COVID hobby for me. My science students will get fossil remnants from me as student of the week rewards. Suggestions welcomed.
  17. Greetings, I am a newbie with a good fossil hunting ground. I have permission to hunt on this property. My previous post regarding a Caudal Vert. didn't get much attention. I was trying to find the age because most other material is Pleistocene. I went looking for more verts in the piles. On the other side of building lot I found a large boulder that was solidified mostly of chalky limestone. Visible on 4 sides are what I suspect are duogong ribs. There are many micro fossils visible. I have been cleaning the sandy dirt away from where the fossils are. They appear to be on the brittle side. The boulder is 24" x 12" and about 150 pounds. A dental probe has allowed me to scrape away areas near the fossils but don't want to push it. I'm looking for suggestions on what you experts do with a specimen this size. Thanks to all of you for your ideas. I am a science teacher in Sarasota County. I know some of you are in my area. I would like to make contact with any local experts. Regards, Michael

    Dugong & ?

    Its been awhile. Ran over to the big sand pit for a few the other day and came up with these certs and one other. Fell from on high so really tough to see what layer they came from.
  19. This is a dugong rib bone. It appears to have cuts slicing cleanly through growth rings before fossilization.
  20. I found this fossil in Englewood, Flordia, on the beach along with some fossilized shark teeth. I think it’s a Dugong rib bone fragment.
  21. Hi all - I did not have time in January when I normally write these up, but thanks to Covid quarantine I managed to get some time last month and write up a comprehensive review on my blog of every single 2019 paper in marine mammal paleontology. Enjoy! https://coastalpaleo.blogspot.com/2020/05/2019-in-review-advances-in-marine.html

    Possible Dugong rib

    Hello, I found what appears to be a fossil in Peace River FL today. It is extremely dense so I am thinking it could be a dugong rib fragment. Any thoughts?
  23. Hi Bone Gang, So awhile back someone posted a picture of an unknown that looked similar to alot of bone pieces I have and that made me go back and take a look at a bunch of them even closer and a couple questions arose about one particular bone scrap. I was looking around for answers about it and ran into this recent book title and am considering getting it...may check it out thru one of the libraries....looks fascinating.. 1) Does anyone happen to have it/have used it and would recommend it? Atlas of Taphonomic Identifications: 1001+ Images of Fossil and Recent Mammal Bone Modification (Vertebrate Paleobiology and Paleoanthropology) 1st ed. 2016 Edition by Yolanda Fernandez-Jalvo (Author), Peter Andrews (Author) So here's a quick pic of some of the types of plain old fairly small chunks of bone that are fairly common from around here in central Florida--Miocene/Pliocene/Pleistocene in age. The Florida folks see em quite a bit. Most are very dense and darker in color from our creeks/rivers ranging from brown/black to a creamy white at rarer inland locales and are heavily mineralized. Some show minor porosity and some have very distinctive longitudinal cracking and others very polished and smooth. Many are dugong rib fragments, probably at least the left 2 in this picture above and some may be from other land critters and be other skeletal parts. Occasionally you see bite marks and borings. There are other hunting areas where the bone fragment finds are more exclusively marine and its common to find other thinner flatter fragments that have more and wider areas of porous bone on the interiors, probably whale or other marine mammals. Here are 2 specimens showing their exterior weathering: Some longitudinal cracks and and an irregular rippling/undulating/uneven surface Some longitudinal cracks and exfoliation.. Here's the one specimen below that I am particularly curious about and looking for your thoughts as it exhibits a number of different features all on the same bone. Seems to pretty water worn and smooth overall, exfoliating a bit but does show some internal details in various places. Thinking it might be a dugong fragment although it doesnt show any characteristic banding in the end view and in one area seems very spongy/porous. Couple of general views showing the longitudinal grooves. A closeup of the dendritic like grooves/structures---maybe the vascular system between the pores? You can see some minor cracks/exfoliation also occuring in spots in the top and lower left.. A 2nd closeup showing a couple of grooves that seem to loop and overlap? Top back edge views showing a rounded now polished cancellous area. A back view showing a .5cm outer layer that has been broken away showing some internal porosity. An end view showing that same porosity. 2) I'm mostly wondering about the longitudinal grooves/lines and whether they are simply water worn/weathering of cracks in the bones or perhaps a polishing of the internal vascular bone feature, some bioerosion activity or maybe both or something else? 3) What do you think about those little grooves with the possible loop or two? Bioerosion? Welcome all explanations/ideas...maybe some simple weathering that I'm just trying to make more complex and am wondering about out loud! Thanks! Regards, Chris

    Dugong or Manatee

    This is an excellent find, but I am unsure how to identify it and I also wanted to share the moment. Why excellent? Any fossil tooth with complete roots is rare and any Manatee or Dugong molar in any shape is rare for me. In 10 years , I have found 5 or 6 of these in Peace River hunting. So my question: Can a Trichechus manatus molar be differentiated from a Metaxytherium floridanum molar and , if so, which is this fossil? Details : Crown height - 45 mm, Crown length - 26 mm; Found in Peace River Watershed. Thanks for all comments and suggestions!!!
  25. Found these fossils at a construction site in Venice Florida. Can I get some help identifying? It would be much appreciated. As a side note I found the huge Megalodon there as well. I think one is an alligator scale? One is a joint of some sort? And one is the tail bone of a dugong? And one is a jawbone with teeth ( feline )? What say all? thanks in advance
