Broken Carnassial Large Predator


Shellseeker

Recommended Posts

My better half has been away for the better part of two week, severely limiting my hunting trips. Today I managed to get away to a location on the Peace River where I have taken some TFF friends previously. It was cool 53 degrees driving there , but once the sun came out , it was OK -- as long as I had my 5 mm wetsuit. I was by myself because getting a dog_walker was a last minute offer.

This location has a line -- clearly Miocene marine on one side and Pleistocene mammal on the other. I had found some  medium sized Hemis, 5-6 Armadillo osteoderms, about half of a good sized dolphin tooth, some gator teeth, a couple of verts... no fantastic finds but a very soothing experience on a bright sunny , cool day.

So, I am thinking last sieve, and this comes up.. for a second laying in the sieve , I thought it was whole.... but no. I did go back for a couple more sieves to try and find the rest of it, but no such luck.

 

Carnassials are very distinctive.  I think this is enough to not only identify the mammal, but also the exact tooth position. The length of the broken enamel is approx 13 mm.

Enjoy !!!   Jack

Thanks,

I was excited by it...even broken

car·nas·si·al
/kärˈnasēəl/
adjective
Zoology
adjective: carnassial
  1. denoting the large upper premolar and lower molar teeth of a carnivore, adapted for shearing flesh.

In my hunting area, cats and dogs, where the largest dog fossil find is likely Dire Wolf and the largest cat is  Panthera onca , Jaguar. True , others exist but they are really rare in my Florida hunting grounds. 

The Florida Museum of Natural History website provides some excellent photos of the jaws and teeth of Dire Wolf  https://www.floridamuseum.ufl.edu/florida-vertebrate-fossils/species/canis-dirus and Jaguar https://www.floridamuseum.ufl.edu/florida-vertebrate-fossils/species/panthera-onca/. From looking at these photos,  possible candidates are Dire Wolf lower p4, and Jaguar upper p4 and lower p4. A photo of the left mandible  from the FLMNH website:

In this TFF Post http://www.thefossilforum.com/index.php?/topic/29885-please-id-a-carnassial/,  @Harry Pristis and @PrehistoricFlorida identified my 1st Jaguar Carnassial,  a lower right mandible "m1" with mostly broken roots. The length of the enamel was 23 millemeters (.90 inch).  Harry provided a valuable photo, which I saved and memorized. Harry also has photos of the Lingual view.

Based on the 32 mm height of root plus enamel, I'm thinking it is like 50% of a lower right p4 from Panthera onca.  Lot of guesstimating here..

Looks a little like Dire Wolf, but don't quote me on that. LOL.

 

Thank you,

Took me a while of looking... You could be right. There are so many similarities between the two animals... and nothing really crisp on the differences.

Thanks for the comeback :fistbump:

I only know this because I found a similar tooth a few years back and asked for ID in the forum and Harry Pristis ID'ed it for me.  :)

 

Your tooth looks very similar.

Harry pointed to this photo in his Gallery in the post you reference.  As always Harry has great photos that add immense value to TFF.  I believe that the Dire Wolf lower carnassial M1 is the other best option for the carnassial fragment I found.

I considered the Dire Wolf M1, and thought the Jaguar p4 was a slightly better fit. Mostly I see the "peak" of the Dire Wolf carnassial to be centered of slightly more over the larger root  than the smaller root.  I do need to concede that the Basin argues Dire Wolf, but the smallest peck on my find seems to argue Jaguar.. It may be the the mandible m1 is not the right comparison.

Thanks.  It is exciting and I try to repay that excitement ( in finding the fossil ) with a specific identification.  Many cases that is not possible but in this case,  I think I have a Panthera Onca lower left p4 carnassial.

I was helped by this photo from a scientific paper on a Pleistocene Jaguar: PLEISTOCENE FELIDAE (MAMMALIA, CARNIVORA) FROM THE KUDARO PALEOLITHIC CAVE SITES IN THE CAUCASUS G.F. Baryshnikov

The photo shows a broken lower p4

I find it amazing that I have the exact same break point.

Not a carnassial. It's a lower p4 from a felid. Size is consistent with jaguar. 

PrehistoricFlorida is correct..It is not a carnassial. The "m1" in the lower jaw IS the carnassial.

See Jaguar lower Jaw above.. Once again The "m1" in the lower jaw IS the carnassial.

Great find Jack and informative thread! Regards, Chris 

 

Thanks Chris,

When I first recognized predator tooth_root, there is a moment of intense thrill_joy that I keep trying to re_create.....

I am fortunate to have kindred spirits on TFF to listen to my ramblings.    Jack

Sorry, I think I had a short circuit in my hard wiring and just had to get this out of my head where it was "rambling around".  :shakehead:
