  1. Hi, it's not the first time that I see a whale fossil with megalodon bite marks. This one comes from Coastal Georgia and measures 7.5" With what percentage of certainty can you know that they are really megalodon marks and not random marks. Thanks!
  2. Got this clam with a mixed lot of fossils recently; this would normally go in the "leaverite" pile, but something odd caught my eye. I'm pretty good with Rorschachery, however, I'm wondering if this one's been bitten. It's about 5" long overall and has a line running through both sides that makes me wonder if something mouthed it at some point. It's most likely geological compression, but more eyes=better. Thoughts? Thanks!

    Ammonite bite mark?

    Hello, I have bought this ammonite, only knowing that it is from Montreuil-Bellay, France. To me it looks like Perisphinctes virguloides, but I am not sure, any ideas? After examining it nearly, I noticed a hole, that looks to perfect to have been made. What do you think about it? Ruler is in cm. Thanks!

    Bite Marks?

    I'd found this dinosaur bone on an online website and it looks like it might have bite marks. It's from the Hell Creek Formation of Harding Co. South Dakota. Here are the pictures.
  5. Hello, I noticed on some pictures on Teeth in the past and recent there are allot of scratch marks. I was wondering what they are ? Perhaps I silly question, but im just learning as i go. Are these from excavating ? or did the Dinosaur did this by biting during its live. (photo by Roby)
  6. Found this on the beach of Wildwood Crest, NJ this week. Interested in what the item is but also interested in what appears to be a bite impression. Not much to go on but any information or thoughts are appreciated. Kind regards, Sean
  7. Help! this Ammonite (Oxytropisoceras so?) is about 8 inches across, its from Texas, does this look like a bite mark? any idea what would have done the biting? I've done some searching but just don't seem to be finding this "type" of bite (maybe my daughter's 4 year old?)

    Bite marked bone?

    I found this in Polk county, Florida a couple months ago and while looking through bones recently I found a couple things I hadn’t noticed and one of them was this small bone fragment that I think has a bite mark in it. It is almost exactly 3/4 inches.
  9. I saw this Madagascar ammonite on website and wonder hole(?) On its surface could be a bite mark. Actually, i've never seen bite mark like this but i looking forward to any new information about it. Thanks.

    Peculiar break or bite marks?

    I took some pictures of all the bison leg bones last night. After I was done taking pictures I was sitting on the couch next to where the were on the floor. Out of the corner of my eye I saw something odd that I hadn’t noticed before. There are lots of chips and breaks on these bones and I have just passed them all off just breaks, however this one is different. Have a look and tell me what you think. It kind of looks like something took a bite out of it. This is the angle that caught my eye. It is the lower end of the femur. The lateral epicondyle. If the bison were standing this would have been a bite to the back inside edge of the knee, kind of where the hamstring would attach in a human. It would be a good way to take a large animal down. Take note of the bottom edge. That is the lateral epicondyle. To the right of the big chunk missing there is a cluster of 4 small punctures into the bone. On the medial epicondyle there is another cluster of 4 puncture marks into the bone. To the right of them is a gouge in the bone. Close up pics below. Lateral condyle. Note the 4 punctures and possibly a 5th or it didn’t quite get a grip and it slid or something. Lateral condyle surface. You can see there is another puncture mark top left near the break (gray with mud in it). The other little holes are where blood vessels passed into the bone. The hole I speak of is a bigger hole with 2 tiny holes on its edge at about 3 and 4 o’clock. I probably should have put arrows or a circle. Diagram of human femur blood vasculature from googling so you can understand bone vasculature. The veins shown in the diagram are larger ones. There would be many little ones as well. That’s what all the holes are in the pic above, besides the largest hole on top left near break. A little bone anatomy explanation. The broken edge at back you’re looking upon is the lateral condyle. You can see the 4 puncture marks there. The other side facing away is the lateral epicondyle. The inside edges are condyles. The outside edges of these structures are epicondyles. The edge closest is the medial epicondyle. It also has 4 puncture marks and a gouge. This shot is ooking down on the break. It is a different texture than parts of the bones I have found that broke recently from falling off the bank, broken while in situ prior to extraction, broken during extraction. . . So the break happened a while back postmortem and had time to weather and smooth the bone a little or it happened while the animal was alive and it didn’t die immediately and the body tried to heal a little. I don’t know which. I tend to think the latter. This is the other femur for comparison that looks completely healthy (besides being dead). That remind me me of Bones from the original Star Trek. “It’s dead Jim. I’m a doctor not a magician.” Or something along those lines. Close set up of the marks on the medial epicondyle. If the marks are from a bite mark, it’s a strange tooth pattern. Puncture marks on the lateral condyle surface. What do do you all think? Maybe cleaning out the puncture marks better would shed more light. Thoughts and comments would be appreciated.

    Edaphosaurus with large predator bite

    From the album: Permian era fossils

    Yet unidentified Edaphosaurus pogonias bone from the Permian era Red Beds site in North Texas, with large unhealed tooth hole from what appears to be a large Dimetrodon's bite, from either the fatal attack, or post-death predation mark.

    Mini Mosasaur collection

    From the album: Marine reptiles and mammals

    A little collection of assorted mosasaur fossils from 2 different places that I got when I first started collecting. 2 different types of vertebrae, one is mosasaur, and the other is a questionable claim of mosasaur, a corprolite that was claimed to be that of a mosasaur, a tooth, & 7 rib fragments. 2 ribs have predation marks, as well as the large vertebra. The large vert has a round tooth indent on the very center. The 2nd rib down has tooth scratches along the surfaces, & 3rd rib down has a round tooth indent in the center, which is probably what caused a strip across the middle to break off. There are 2 other tooth marks on that rib as well, forming a diagonal line from above left of the center indent, breaking off a piece along the top, to below right.

    Theropod Vertebra

    From the album: Reptile Fossils

    Cervical vertebra of a theropod dinosaur (possibly Spinosaurid) with series of scratches on one side. It is likely that these scrathes are gnaw marks from different animals due to the different sizes of the marks. Location: Kem Kem beds, Morocco Age: Cenomanian, Upper Cretaceous

    Framed Meg Teeth. Before people start going off on me hahahaha FYI, we DO know its not accurately depicted, we DO know they are technically backwards, we DO know we are missing some. This is an artistic representation for the customer representing a portion of meg teeth found in one hole!
