    Hemiauchenia M3

    I decided to separate the 2 finds here from my finds from Saturday. One is pretty enough to have its own thread.. This is a upper jaw section of Hemiauchenia macrocephala from the University of Florida Vertebrate Paleontology Database. M3, M2, M1 upper right maxilla Here is almost my best find Saturday... As I picked it out of the sieve, I knew it was an upper jaw camelid, most likely Hemiauchenia. I took it over to my kayak and snapped a couple of photos. I have been educated , mostly by Harry in other threads to recognize 100 % enamel teeth (no dentine or cementum) and what that means... In this case, an young adult camel has a barely erupted tooth, still in the process of growing roots, when it was likely killed by a predator a couple of million years ago. (I like to imagine stories). Look at the 2nd last tooth ... all enamel, a bare hint of root... Initially I thought this might be the M2, but looking at this last photo, comparing to the UF 271830 jaw, I switched to the M3.. Can you see why? I sent it to Richard Hulbert last night asking insight on the filigree pattern. I said "almost" above... There is a broken fragment of a tooth that I almost tossed (NEVER toss anything you do not recognize as a rock). Serrations on a 50 mm fragment !!!! That gets my imagination going. While Megs are all over Florida, there has never been a fragment found at this location.. It is not impossible that a Meg might have wandered in to an unlikely location.. Another possibility is Great White.. We have found some small GWs, but none over 2 inches.. This would be from a max sized GW... So , shark experts could tell me what they know about serrations from larger sharks. these look uniform . exact same size... and if someone does not recognize this as Meg or GW there is yet another possibility of large teeth with serrations...
  2. Back on the Peace River yesterday. Another cool start to the day, 63* F when I launched at 8:00am. Headed back to where I found the camel cuboid last week and found there was still plenty of gravel to sift through. The morning progressed with a couple of nice, if partial, alligator teeth, many small shark teeth (nearly 200 by the end of day) a partial deer tooth and a couple of turtle leg spurs (5 for the day). The afternoon produced a couple of unidentified bones I will have to research and a very nice Llama astragalus - Hemiauchenia macrocephalus. Makes sense after finding the cuboid last week. Wasn't sure what it belonged to when I first pulled it up as I thought it was too small for bison and too large for deer. At 2 1/2" x 1 7/8" x 1 1/2" it fit llama just right in my reference materials. An overall shot of the best of the day: Some closer up photos of the astragalus: The biggest bone of the day is unidentified and I was leaning toward a piece of Giant Tortoise shell, mostly because I can't think of any other candidate. It measures 5 5/8" x 2 5/8" x 2". Can a Tortoise shell be that thick? Another unknown bone that I need to search for came in at 3 1/8" L x 1 1/2" T x 1/2" W, maybe some type of ulna? Did not see another person on the river all day. On the paddle home I took some photos of the ride to show the beauty of the river and the power it has to take down trees along the banks. In the first you can see the downed palm trees along the eroded bank - I always am awed by the cypress tree roots and the patterns they create as they spread (approaching some on the right) - To me there looks to be the carved face of an old man in the photo above. Finally, a couple of shots of some massive old oaks that did not survive the last rainy season - Looking forward to the next hunt!
