Echinoid Eupatagus antillarium commonly called the Florida sea biscuit.... I have found many of these over the years but this one is the first one that I have ever found that may show signs of predation? What does everyone think? Thanks for you input!

Hi everyone. Iv'e been thinking about doing this for years and now, here I am! I have some interesting beach finds from "Sharks tooth island" and emerald isle, north carolina beaches. My favorite has obvious tooth marks. Black brown bone shard, about 1 inch long. Looks like something bit into the bone and cracked it open. There are a few molar marks and smaller tooth marks as well. The hole shown is I think a tendon insertion hole? So many predation marks on it. So cool! Any ideas of what the bone is and what had a good meal off of it?

Fossilized bone found with what looks to be predation marks. Help Id please. Thanks
Backcountryhiker posted a topic in Fossil ID
Hello everyone, while I was getting some exercise exploring the badlands here in central Alberta (Red Deer river valley Scollard formation I believe) I found a piece of fossilized bone that must have been recently exposed due to spring thaw. I am no guru however it appears to have some predation marks on it (third picture left side) & to me looks like it could be a leg bone? I'm looking for some help confirm these are in fact predation marks & also to ID the bone itself if possible. I know its difficult due to it being just a small fragment but any help or additional info would be greatly appreciated. The fossil measures approximately 9cm in length by 4.5cm at the fat end & roughly 3cm at the thin end. Hope that helps. Thank you in advance for the help!

This is a turtle shell fragment I collected today from Galveston Bay dredge spoils. (Late Pleistocene Beaumont formation) Is this a partially healed bite mark or some sort of pathology?

Hello, I found this piece of bone in Manatee county, FL. It is 5” or 127 mm across the widest part. Looking for ID on bone if possible please and also wondering if it’s possible that the two little indentions on the flatter side are predation marks? thank you!

This is a dugong rib bone. It appears to have cuts slicing cleanly through growth rings before fossilization.

Here is a hadrosaur ungal that appears to have been chomped on postmortem by a big carnivore, like Rex. Found in Hellcreek SD. What do you all think?

My fossil buddy and I went out this last Saturday, decided not to kayak because it was too windy, so we avoided the Peace or Caloosahatchie rivers and instead headed north to one of our favorite walk in spots to screen for sharks teeth. I was anticipating the water would be warmer than the air, ( 44 degrees) and I was right. It was actually nice to walk the mile into the site in cool air for a change...no bugs, beatiful sunshine and several blooming wild trees. The river was at just the right height. I could show you all the nice shark's teeth I found, but I had decided to give them to a young man at my church who wears a shark's tooth necklace. I have him a nice little box, with an accompanying sheet drawing of each type of fossil and a name so he could learn to identify them....sand, bull, hemipristis, tiger, and even a nice by small megaladon tooth, a couple pieces of ivory, part of a horse tooth, a barracuda tooth, and beatiful gator tooth, a nice 2 inch section of deer antler with its base, a puffer fish plate, several turtle pieces....a lot. However there were two i kept for myself. The vertebrae pictured, that was so perfect I thought it might be recent, but the flame test didn't reveal even a little hint of smell, and the nice shell with evidence of a predator...I can image something smashing into this living busycon, stabbing it, and then ripping the mollusk out of its shell to eat...racoon do you think? Strong teeth. At any rate it was great to be out again. BTW, I am going to post the vertebrae in ids cause I have no idea what it is. It is an inch across....in my excitement to photograph it because it is so perfect, I neglected to add a ruler....sorruy.

Hi everyone, I got this interesting peripheral turtle shell from the Late Campanian Wenonah formation of NJ. It is not reworked and seems to be IDable. It also has some interesting shark predation marks on the top of the first pic. It is about 2.75” X 2.25” @non-remanié Thanks for any help!

If this is truly what I suspect it is, it could be the most extraordinary fossil I've found to date. This was found at Bayfront Park, which is Calvert Formation. It appears to be some kind of bone, probably from a marine mammal. When I first found it, that's all I thought it was: a bone. It was only when I was back home from my trip and sorting through all my finds that I noticed something peculiar. There was something protruding from the bone. I couldn't believe my eyes. It was a fossilized shark tooth. I have always thought it would be incredible to find a fossil with tooth marks or even an entire tooth embedded in it, but I never thought it would actually happen! My best guess at the moment is that this is an ear bone from a small whale or dolphin that fell victim to a lemon shark, and when the shark bit the animal, its tooth was jutted into the bone. When the animal died, its bone fossilized with the tooth still inside it. My question for you is not whether or not the object protruding from the find is a lemon shark tooth; that is fairly clear. I am looking for confirmation that the fossil is indeed a bone, and would like to know what type of bone it is and from what animal. Since I believe this to be an extremely uncommon find, I am considering bringing it to the Calvert Marine Museum to be inspected by the experts there, and if they want to keep it I will gladly donate it. Thank you in advance. ~David (P.S. The tooth is only fully visible in the last picture)

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. -

My Jurassic Park - Injured, Predation or Diseased Dinosaur Bones
Troodon posted a topic in Member Collections
Thought our members might be interested in seeing the few bones in my collection that have some sort of paleopathological features on it. Most of the time when someone is showing us a bone we are looking at some perdation due to bites and wonder if its real. Hopfully that is not the case here. Let me begin by suggesting a good book on the subject Mesozic Vertebrate Life by Tanke, Carpenter and Skrepnick. It covers many areas but several chapters on this subject. What I would like to do is to show you my specimens but ask anyone to post Dinosaur specimens that they may have in their collection that have some features on it. Always interested in seeing other specimens and not has much technical papers. Most of what I'm describing is my guess or no guess, so other opinions are always welcomed Allosaurus sp. To me this looks like bad case of arthritis around the bone. The bone should be smooth. Wonder if they took asprin Struthiomimus sp. I'm not sure what to say on this Tibia. There is a 5 inch wide bulge in the middle of the bone some type of growth or infection? Had to be painful. Second photo is comparison with a normal bone. Theropod indet. A carpal of a theropod with some lesion or scar around the bone. May be a healing scar due to an injury. A toe bone with what looks a theropod bite that has displaced some bone. Looks like some healing occured so it was alive, ouch! Anzu wyliei A toe bone with what looks like a postmortem bite mark. Its shape says Crocodile. Remember the bone is hollow so it would not take much to cause the depression. Edmontosaurus annectens A huge 5" across ungal from Baker Montana. My guess is disease but could be has a result of bite. This is what a normal one should be smooth both sides.

My best fossil. The Anomalocaridid, Amplectobelua symbrachiata feeding appendage with a trilobite curiously attached to the end. Amplectobelua predation on trilobites or trilobite predation on a dead Amplectobelua? From Chengjiang. -
Hi All I was hunting in Wheeler Shale a week ago... When I split open this. Looks like as if the Asaphiscus had been predated on. Could I be right? Wondering what others think. Thanks, SP
