Show us your Devonian Epizoans & Pathological Brachiopods!
Brach3 posted a topic in General Fossil Discussion
Dear all, if Devonian Epizoans (Epibionts) & Pathological Brachiopods (all the periods) are a fascinating group of fossils for you and you want to discuss anything about their paleoecology, please post your photos (specimens) in this thread.- 220 replies

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 gr -
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?

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 t- 28 replies

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

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

600 Million Years Ago, the First Scavengers Lurked in Dark Ocean Gardens, By Asher Elbein, New York Times https://www.nytimes.com/2018/11/30/science/ediacaran-period-predators.html The bizarre organisms of the Ediacaran Period have long puzzled researchers. Fossil discoveries suggest these ecosystems may have been more complicated than once thought. The paper is: James G. Gehling, Mary L. Droser, 2018, Ediacaran scavenging as a prelude to predation.

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. -
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 -
So, can anyone shatter my dreams with THIS one? Lol no, I'm really extremely appreciative of the help Ive been getting with questionable fossils, and the chance to learn important and helpful information! the description says it all...this is supposed to be a tyrannosaurus fibula fragment. Seems legit to me, but I could definitely use other opinions. This is a hell creeker.

Hi all, So this little bone piece was found at the beach of Wassenaar, Netherlands; it’s from the late Pleistocene, 40’000 years old. I got two questions on this one: Is it possible to say anything more about this bone fragment (eg what animal/what part of the skeleton)? In the last picture, are those predation marks? I can take better pictures if needed. Thanks in advance for your help! Max

This has been bugging me for some time now, and I can't find any papers that answer these questions. I'm honestly surprised at how little research seems to have been done about these topics. 1. How fast were they compared to some modern-day benthic animals? Were they slow and cumbersome, or were they fast and agile? How did this change through time/environment? I assume that the earlier, Cambro-Ordovician trilobites would have been a fair bit slower than their later counterparts due to a lack of nektic predators that could easily pierce their armor, but this is just my assumption.

Posting this because the results of predation can impact (the interpretation of) bivalve taphonomy. Besides,I think documentation like this is rare. Love to be proven wrong,BTW feifdoc_spinepibiontsantipredathorn-spondys.pdf outtake:

Can someone tell me about the crushing that is seen in the walls of this ammonites chambers? Its odd to me that in the areas where the entire wall is gone, the geode/vug areas still occur as you would expect them to with chambers? I picked this up for $10 after noticing the crushing, because I don't have any like that in my collection
