Shellseeker Posted July 22, 2020 Share Posted July 22, 2020 I found this Hemipristis serra tooth a couple of years back. Looking at the left photo, I noted the bite marks, and the fact that the distance between each bite mark was approximately the same as the distance between this tooth's serrations!! So I make up a possible story. This shark was in a feeding frenzy, and under the feeding pressure, this tooth (like other shark teeth) fell out, but before it could clear the mouth area, the shark bit down again, leaving these telltale marks. There are likely other "possibles", but I prefer this one. Now more recently, I have another tooth, in this case a Galeocerdo cuvier, and interestingly it also has a bite mark. Once again the distance seems to be the same between the bite marks and between the serrations on this tooth. I notice a lot. Look at that little hole in the enamel above the bite marks. I have no story that explains that hole. But my story breaks down. The bite marks on THIS tooth seem post _ fossilization not in the enamel, but on the enamel. So I opened this thread to attract others who have bite marks on their shark teeth, and ask some of the shark tooth experts their insights. @Northern Sharks@Al Dente@siteseer@MarcoSr@Plax@sixgill pete 6 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
Shellseeker Posted July 22, 2020 Author Share Posted July 22, 2020 Another thread that shows a Meg, with similar bite marks and a different theory from @mattbsharks http://www.thefossilforum.com/index.php?/topic/79561-megalodon-tooth-damage/ Just providing a little more input 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

sixgill pete Posted July 22, 2020 Share Posted July 22, 2020 Jack, in all the years and thousands of shark teeth I have found, I have yet to find one that I thought might have been bitten. Feeding damage yes, but not bitten. With that said, that hemi is very cool. I can picture your theory in my mind. I would say that is a distinct possibility. Amazing tooth. As far as the tiger, I think those are from something else, including the boring.

So I have found 2 in 10 years like this, and the hemi is the better one. I was pleased to find the TFF thread on the Meg with similar bites. I had been wondering if other fossil hunter who find lots of small teeth were finding this type of damage... I have a different type of byte that I have seen more frequently (if it is a bite). I find more (maybe 1-2 a year) of this type of damage. As you likely know, from seeing my posts, I have a great imagination, weaving my stories around my finds.... I just hope a third are correct...

Do you have knowledge on other shark teeth.. I am wondering things like 1) more large teeth .. Megs, Makos, GW, Hemis, 2) more labial than lingual. I do not have enough numbers to form a view, thus my purpose for this thread.

I do not have enough numbers to form a view, thus my purpose for this thread. All of my Hemipristis teeth have the marks on the lingual side. I have lots of teeth of different shark species with single scratches, scrapes, possible single puncture holes, but none that I can remember that I was sure that the marks were caused by the shark biting its own tooth like the Hemipristis teeth with multiple marks from multiple serrations.

siteseer Posted July 24, 2020 Share Posted July 24, 2020 Hi Jack, I have a Hemipristis with serration marks like yours too. It was a gift from a friend who had collected in the Bone Valley area in the 60's. Jess 1 Link to comment Share on other sites More sharing options...
