    Florida Shark Tooth Help

    I am finally going through my Florida shark teeth. Most of these are from the Peace River. Hoping to get confirmations and corrections on my tentative IDs. I have numbered the groupings of taxa. Scale is in mm. No. 1: Galeocerdo cuvier? No. 2: Negaprion brevirostris? No. 3: Negaprion brevirostris? No. 4: Charcarhinus spp.? No. 5: Odontaspis taurus? No. 6: Hemipristis serra? No. 7: Galeocerdo aduncus? G. cuvier?
  2. Hey gang, Going thru chucking things out of the garage piles and noticed this good sized, highly weathered chunk of bone which has some parallel grooves/marks that I'm interpreting as possible shark bites. Want to confirm that assumption and ask if that is the case, could the upper 3 somewhat parallel lines and the 2 lower lines be single bites showing 3 teeth and 2 teeth respectively? The one mark on the upper left seems to be slightly curved so would that be consistent with a different angle/different shaped tooth position? Just wondering what you all think? Regards, Chris

    Can Someone ID This Petrosal?

    Here's a land mammal petrosal that I've just retrieved from storage. It's from the Santa Fe River, so it's Pliocene or later. It appears to be complete. These petrosals all look about the same to me. Help me out here.

    camelid proximal phalanges B

    From the album: BONES

    This is the third toe bone of a lamine (that is, related to llamas rather than dromedaries) camelid from the Plio-Pleistocene of Florida. Recovered from a Florida river.

  5. So I've been looking around at the pile in the garage, trying to get rid of some of the junk and taking some photos that I thought you all might be interested in. I think some of you may have picked on my fascination with earbones...If you dont have that fascination keep scrolling....Well, here's one partial example with multiple views that was a little more different than most but I think its a whale bulla. Its preservation is a little different and there is an extra cavity where normally you would have solid bone...just my guess anyways. Also another shot of it on the very left showing some of the other bullas and its relative difference. Maybe its something completely different. Here's a neat little blob of casts of sponge borings and I've been trying to get a real sharp close up of what I think is a bryozoan in the same matrix but its the best I can do. The unknown is really cool but I just cant capture the real coolness with my cell phone..The scaley looking fragment is approximately 6mm long.The preservation detail is remarkable given its only a fragment. I suppose I really should put this in the ID section as I was wondering if these are all same Sconsia species. S. hodgii? Not that important...Didnt realize I had 4 of them until recently. A couple of them have taller spires and I just cant decide if they are all the same or not. Here's a Chesapecten. C madisonius I think. (photos of after and before) that I put in 2-3 hrs here and there trying to clean. Was using dental picks and a brass brush to remove the sandy matrix and endless soaking. I could do more I suppose but I dont have the patience for prepping. I had ideas of separating the valves but maybe in another lifetime. It has all kinds of very small sponge boring holes and grooves that make me absolute crazy. LOL. Was hoping to find that it had attached barnacles but they were gone and I only had scars left. Those of you who have that patience to prep I applaud you! Lastly for all you barnacle and brach fans...I know there are thousands of you..I am one..LOL. So a complete brach Discinisca lugrubris around here is pretty rare. I only have a few and this is the 2nd of 2 brach/barnacle associations I have. What makes this barnacle on top of a brach extra special special was that when I recently was looking for plates/stuff inside the barnacle (which had no plates and mostly just sand) I found another brach...a tiny juvenile! Yeah! So its time for breakfast...Continued hunting success! Regards, Chris

    Something mysterious

    I have wondered about this one for several years. It is from the east side of Lake Turkana, in Kenya but I wasn't at the actual spot from where it was picked up, so I don't know anything about the specifics of the location. This was one of at least a dozen specimens that I saw. The other side looks the same as what you can see in the photo. I have wondered if it could be a stromatolite but the shape is odd for that. Could it be some sort of evaporative feature? It is the only one I have, so I haven't tried cutting it open. I'd love to hear some opinions.

    Need help identifying this bivalve

    Attached is a bivalve I found in the Bradenton, FL area. It looks like a “cats-paw”. Can someone help me with the identification of this fine fossil? Thanks!

    Itty Bitty Bone Hopefully !!!!!!!

    I occasionally grab a handful of micro-matrix from Cookie Cutter Creek and examine it. Very tedious work. Last night I ran across what I believe is a bone. Hopefully those educated on vertebrates can tell me if it is bone and if so, from what!!!! I am dreaming that it is avian in origin. So so delicate. I am shocked I didn't destroy it during it's photo-op. Thanks for looking. Mike
  9. So I was recently going thru some Florida tooth material (Mio/Plio-Pleistocene) from years ago and realized I had lumped a bunch of this stuff in a packet without investigating them too thoroughly. I started to bug Jeff about several and thought I'd see what you all thought as well so I could learn something more from you all. So just 4 teeth for this thread. I was noticing #1's serrations were pretty coarse and well developed and unusual and I was asking about its possibilities and the meg possibility came up. I then found #2 tonight in another bag and it has some similarities to #1. Neither seem very thick/robust or show a bourlette but their serrations are definitely different than most I have seen. #3 has those finer serrations and shape I usually have put into the Carcharhinus ID bucket. Could they all be Carcharhinus? And lastly #4 may be pathological? What say you all? I know messing with single teeth ID's is pushing the envelope but appreciate any thoughts... Here's another view of just # 1 and #2. And lastly #4: Thanks for the help. Regards, Chris

    Glycymeris sp

    From the album: The Mollusca of the Banjaard

    An incomplete bittersweet clam specimen. Because the hinge is missing, it becomes very hard to determine which species it is, which also makes it difficult to determine the age of the specimen, as both Pliocene and Eemian (which contain different species) sediments occur on the Banjaard. Chances are higher that it's an Eemian species, simply because Eemian sediments are more common, but no definite conclusion can be drawn. Status: locally extinct Fossil occurrence: uncommon
