Xiphactinus Posted March 31, 2016 Share Posted March 31, 2016 I have the pen from a giant squid from Kansas with circular chunks missing. Most likely from a shark. http://oceansofkansas.com/Invertebrates/Tusoteuthis-Garrett1.jpg Link to comment Share on other sites More sharing options...
Darktooth Posted March 31, 2016 Share Posted March 31, 2016 My cream colored meg appears to have been bitten not once, but twice from its ptevious owner during the feeding frenzy. The mako appears to have a bite mark on the root but the blade itself is pristine. 1 I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Past Hunter Posted April 1, 2016 Author Share Posted April 1, 2016 I thought I would throw a few more in the mix. "If you choose not to decide. You still have made a choice." - Rush Link to comment Share on other sites More sharing options...

glu Posted April 3, 2016 Share Posted April 3, 2016 By the way I've found in the chalk this crushed Echinocorys. Could this be predated or is it a geological compression? Sorry for the bad pictures Link to comment Share on other sites More sharing options...

Terry Dactyll Posted April 4, 2016 Share Posted April 4, 2016 I nearly forgotton this one....Its not only bitten , its swallowed and still in the stomach of an Icthyosaur....The hooks you see in the preserved stomach are from squid tentacles....So the squid was bitten, swallowed and digested....

Harry Pristis Posted April 4, 2016 Share Posted April 4, 2016 Here are some examples from a possible bear-dog den: http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
bcfossilcollector Posted April 5, 2016 Share Posted April 5, 2016 (edited) Here is an example of an Elrathia Kingi with a possible Anomalocaris bite out of it. I say possible because some of these specimens are so heavily brushed its hard to tell even under magnification.

newdog65 Posted November 15, 2016 Share Posted November 15, 2016 This is a very special trilo I found last year - undescribed, and also has what appears to be healed pleural tips. Enjoy Chris N Link to comment Share on other sites More sharing options...

fossilcrazee Posted February 1, 2021 Share Posted February 1, 2021 Miocene/Pliocene Yorktown Formation (Beaufort County, NC) Whale vertebra with deep gashes symmetrically arranged around the central axis of the vertebra. I hypothesize that this whale was attacked by a megalodon shark using the same predatory strike present-day sharks use on cetaceans: they bite the tail to immobilize the whale which is then unable to reach the surface to breathe. The photographs show each side of the vertebra, rotated on it's axis. The slashes start on the right on each photo. 1 Link to comment Share on other sites More sharing options...
siteseer Posted February 5, 2021 Share Posted February 5, 2021 The apparent gnaw marks on the dinosaur bone are interesting. There were no rodents yet during the Mesozoic (no rodents until the latest Paleocene/earliest Eocene) but there were mammals with similar incisors, the multituberculates, and they are known from at least the early Cretaceous of North Africa Jess 1 Link to comment Share on other sites More sharing options...

This thread is awesome, love finding bite marks on bone, I'll get to posting my own soon enough. Link to comment Share on other sites More sharing options...
PaleoNoel Posted February 7, 2021 Share Posted February 7, 2021 Here's a big chunk of whale bone from NC's Green Mill Run with some nice bite marks: Link to comment Share on other sites More sharing options...
PaleoNoel Posted February 7, 2021 Share Posted February 7, 2021 And a piece of marine reptile bone from Big Brook NJ. Marks could have come from anything, either predation or scavenging, however, the Cretaceous shark Squalicorax (a common find at this spot) is well known for being an opportunistic scavenger of marine carrion, with its teeth even being found in the bones of terrestrial dinosaurs which had been washed out to sea.
