Shellseeker Posted April 18, 2015 Share Posted April 18, 2015 I was out with a very good fossil buddy. Usually I cover the transportation gas, boat and he wants me to know that he appreciates the contribution. Today he gave me the 1st fossil photo below. I found the 2nd which I am thinking is Palaeolama Mirifica M3. He found the 3rd. and neither of us knew the ID. I am a very lucky man. Here is the request for an IDentification. Normally Serrations & Cusps belong to RICs. What mammal is this? Thanks for all responses, comments, and suggested IDs.

jcbshark Posted April 19, 2015 Share Posted April 19, 2015 Nice finds Jack, I've been having a little luck with GW teeth lately too The only shark tooth I've found less of than those is cow, of which I've only found one of. That bottom tooth is really interesting, can't wait to see what the experts say Every once in a great while it's not just a big rock down there!

Miatria Posted April 19, 2015 Share Posted April 19, 2015 Great finds! I think that bottom tooth is the coolest fossil I've ever seen. Can't wait to hear the ID. Zookeeperfossils.com Link to comment Share on other sites More sharing options...

Shellseeker Posted April 19, 2015 Author Share Posted April 19, 2015 Is that last one a squalodon? oops, squalodon is double rooted. Some kind of dolphin? I do not know. However, I guessed marine mammal; my hunting partner guessed pig family (tapir, peccary, etc). On this one I am just eating my popcorn and I am happy that many will gain new knowledge on this one, including me, The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

digit Posted April 19, 2015 Share Posted April 19, 2015 I'd have to think toothed whale but what do I know? I'd burst at the seams if this came up in my sifter. I'll wait with the others here and see what opinion someone with authoritative knowledge chimes in with. Finishing up my last coral reef research trip of the year and hoping to make it back before the rivers head back up. It seems to have been a difficult season in South Florida this year with high river levels and I hope to dip a sifter in before all the fun is through for this season. -Ken Link to comment Share on other sites More sharing options...
jlar7607 Posted April 19, 2015 Share Posted April 19, 2015 Photos have been sent to Richard Hulbert we will see what he comes up with.Asked my buddy louis he always knows but he didnt know this one ! Link to comment Share on other sites More sharing options...
digit Posted April 19, 2015 Share Posted April 19, 2015 Always great having a resource like Dr. Hulbert to consult with. I brought a number of my Peace River finds to the Thomas Farm dig last year and he was able to quickly educate me on a lot of my finds. Turned out I had more interesting things than I thought. I'm betting there are a few TFF members who will weigh in soon as well. Cheers. -Ken Link to comment Share on other sites More sharing options...

Al Dente Posted April 19, 2015 Share Posted April 19, 2015 Maybe Xenosmilus incisor? I think they are serrated. Link to comment Share on other sites More sharing options...
Shellseeker Posted April 19, 2015 Author Share Posted April 19, 2015 Maybe Xenosmilus incisor? I think they are serrated. Thanks Al Dente, Good article on the cookie-cutter cat (even in Florida) here. http://www.wired.com/2011/10/cookie-cutter-cat-not-as-cute-the-name-sounds/ and TFF threads that reference it. http://www.thefossilforum.com/index.php?/topic/11604-odd-tooth/ http://www.thefossilforum.com/index.php?/topic/13812-feline-fossils/ Old TFF threads are a tremendous resource. I had never heard of Xenosmilus before, and have no clue whether this incisor belongs. Still eating the popcorn.

Shellseeker Posted April 19, 2015 Author Share Posted April 19, 2015 Pursuing the quarry. " The lower incisors of Xenosmilus are larger than in Smilodon, H. sermu, and H. ischyrus. They are recurved, cone shaped, with the anteroposterior length greater than the transverse. They are all graded in size, with Incisor #3, about 2/3rds the size of the canine. All the incisors show wear facets on both the lateral and medial sides from occlusion with the upper incisors. There are two small lateral cusps on each of the incsors, with the medial cusp being slightly elavated compared to the lateral. All the incisors have lateral and medial serrated ridges that terminate in serrated cuspules" pp54 . The Other Saber-tooths, Naples, Martin, Babiarz.

Harry Pristis Posted April 19, 2015 Share Posted April 19, 2015 I didn't look closely enough. I think that Al Dente made a good call. Xenosmilus is a rare cat with distinctive teeth. You can see some of the serrations preserved in this resin cast from Babiarz. 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...

Shellseeker Posted April 21, 2015 Author Share Posted April 21, 2015 Photos have been sent to Richard Hulbert we will see what he comes up with.Asked my buddy louis he always knows but he didnt know this one ! Response from RIchard Hulbert: I am reasonably confident that this is an incisor of the sabertoothed cat Dinobastis serus (also known as Homotherium serum). Xenosmilus hodsonae is a closely related species that also has such serrated incisors, but it is from the early Pleistocene and I am assuming this is a Peace River find which means it should be late Pleistocene. But if it is from one of the shell pits in southern De Soto County then it could be early Pleistocene. Although widespread in the western US, Dinobastis serus was previously known from only one locality in the Southeast, the Reddick Site in Marion County, Florida. If the identification is confirmed through direct comparisons, then this would be the second Florida record and the first from the southern part of the state. At least , it is down to one of two choices and Dinobastis serus is in the lead. We are working with Richard to confirm the identification. I am excited because of the rarity of Florida fossil records for these two Saber_Tooths.

digit Posted April 21, 2015 Share Posted April 21, 2015 That is way too cool. When I fill out my Florida Fossil Permit application each year and list the items I've found during the previous year they are always so humdrum and pedestrian. Never once have I pulled something from the Peace that might actually be scientifically important. I'm really excited for you. Cheers. -Ken Link to comment Share on other sites More sharing options...

Shellseeker Posted April 21, 2015 Author Share Posted April 21, 2015 jealous of that Dinobast or Smilus whichever it is..... impressive find not an animal I would have wanted to encounter up close I will be booking my next trip to Florida soon. I was out in a remote area of the Peace River today with a couple of fossil buddies. Naturally we talked about this topic. While standing in the river, we imagined what it must have been like to spot one of these predators on the far bank 1/2 a mya. A lot of jokes about which of the 3 of us was slowest. Soon after we were drenched by a front coming thru with thunder and lightening. Then we returned to shoveling.

Miatria Posted April 29, 2015 Share Posted April 29, 2015 Just heard the joke in "The Imitation Game": 2 men facing a bear (smilodon, etc). 1 starts praying and the other starts lacing his shoes. The praying man says, "You can't outrun a bear," and his companion replies, "I just have to outrun you." Zookeeperfossils.com Link to comment Share on other sites More sharing options...
