Yesterday was going to dip into the high 40s F in the early morning and top off at low 70s. I know it is not the same as being up north, but deciding to step into water when the air temps are 50 degrees always generates a gasp even with a 5 mm wetsuit on . However, opportunities are few in December for me. We are hunting a location that used to produce Miocene fossils , but has been heavily worked. Mostly it produces small shark teeth today. However, like @Balance, I have learned something about layers.. and I know that I may be able to dig thru mud and sand clay, and even gravel and discover an un_dug pocket. We had found a spot where small teeth had rolled in so we could get 10-12 in a sieve and spent about 90 minutes digging. There were also a few broken Ray teeth and barbs, but I hoped for something more for this day beyond the small shark teeth. I was about to pack up, move downstream probing for gravel. For whatever reason, last sieve at this location was going to be a little upstream. There is quite a bit of gravel from old discard piles.. and a pretty deep hole. I like digging in deep holes because I favor deep water. So I stuck my shovel in the bottom of the hole and the tip hit gravel below sand and leaves. Not too much in that 1st sieve, except a couple of small rostral teeth from the knife toothed sawfish and I have hunted here quite a bit previously. This is likely from a mid_miocene Tridactyl horse named Nannippus aztecus. and that find just made my day. I was no longer thinking about what laid downstream. In subsequent sieves, we broke thru the gravel into clay... This was the only Meg I found and that was enough. I like Miocene horses a lot better than Megs . This is a pretty good Meg .. root, serrations, color, a little tip damage. My friend found 3 Megs , none quite as good as this one. We stayed the rest of the day.. Another nicer horse tooth. Multiple teeth from the same animal always get the juices flowing but this one is right lower rather than left. Too quickly the fossils in the sieves got fewer and fewer... We ran out of the pocket. The other thing that ran out was time. There are other pockets, but those will have to wait for another day.

It was pretty cool yesterday. As a youth, I used to swim in Vermont quarries. But having been in Florida for 20+ years, I define cool differently. As I stepped out of my truck at 6:45 am, it was 57 degrees Fahrenheit and I was about to go swimming. I am not completely crazy. I had my 5mm shorty wetsuit on. Very successful day, Slow to start, moved twice and then consistent finds. A couple of Notes: There is a row or 2 of Tigers and 3-4 rows of Bull _ Dusky teeth those species dominate here. I pick up a some interesting bones to Identify later.... The Makos (55 and 41 mm) and lower Hemi (45 mm) were definitely appreciated. Tiger shark teeth are as large as I find anywhere. This might be P. contortus. Then this Osteoderm on the right, compared to Alligator... I almost tossed it away... but then I thought it could be Crocodile.... There is a cluster of 5 mostly whole or partial Horse teeth... They are the primary request for Identification or comments.. #1 #2 #3 Really beaten up Tridactyl,, Pretty.. need to stare at it to see if I can find the protocone. High Majority of Tridactyl Horses here are N peninsulatus #4 Almost all there... I think an Id is possible... #5 Lots missing... may be Equus.. lower partial All comments and suggestions appreciated... Jack @fossillarry

Went out Hunting both Wednesday and Thursday. Already posted Thursday finds. This was a trip back to my happy place, not huntable during the summer rains. To me this hunting trip challenges the conventional wisdom about going home again. Although I have sorted out most broken shark teeth, this is a fair representation of types of teeth 60% Bull or Dusky, 25% Tiger cuvier, 10 % Lemons. There are lots of broken bones, I collected some that I think I might want to identify. There is a lot of whale jaw... here is an example with some bite marks. I make an assumption that these are shark bites, but possibly someone with more knowledge can confirm. Land predators might leave different scars. I used to not recognize these but then Bobby identified them for me in a thread years ago ... and they are rare enough so I always keep them... Staying in the marine mammal finds, an overly worn tooth Some infrequent finds here... There are a couple of Alligator teeth and a nice scute in the photo, but Crocodile is rare... Likely a Glyptodont edge osteoderm Not sure what this one of a kind is... Reminds me of one of Harry's shrimp burrows in miniature. 2 Complete bones. The longer , thinner one is a Proximal Phalanx from Hemiauchenia gracilis, a Blancan fauna that helped me age this location years ago. Below is a research paper photo of 3 Proximal Phalanx of H. gracilis. The top 2 was within the range of 80-85 mm in length. and the caption that the muscle attachments on the proximal end resemble a "W".... The 2nd bone is an Equus Proximal Phalanx.. I found 6 Horse teeth... 4 Equus and 2 Tridactly , one lower , one upper.. The lower I recognize.. it is Nannippus peninsulatus, one of the smallest and most recent Florida Tridactyl Horse that existed in the late Pliocene (Florida Blancan Land mammal age) The other small horse tooth is a badly damaged upper. It does seems to be Nannippus, and that is why I'll try to Identify it . @fossillarry Measurements of the find are APL 11 mm, TRW 10 mm, Crown Height 30 mm. Since this find is missing about 20 % of the tooth, the APL is more likely 13-14 mm Here is an Upper Nannippus Molar to compare APL 11 x 15 x 49 mm. Enjoy, As always suggestions and comments are always appreciated.

Out hunting today, and that's a good thing. My primary exercise is Fossil Hunting and it is strenuous for me. I need to hunt twice a week to stay in reasonable shape but for the month of September, I was out hunting 5 times. The "special" finds are always more exciting but today there were not many combined with finding fewer small shark teeth than previous outings.. In the last 90 minutes, we decided to visit previously fruitful locations, each filling a sieve and moving on if nothing special was showing up. With 30 minutes to go, along with 7 small shark teeth, 2 dermal denticles, and a couple of sawfish rostral teeth, out pops a pretty nice Meg. At first I thought unbroken, but definitely a heartbreaker.. Great fat root, nice serrations. Even broken , this is special... 2nd last sieve, a tridactyl horse upper molar, slightly distressed and possibly identifiable. I think it is likely Nannippus, but I will be trying to ID species. Great day. No rain, slightly cooler and found a couple of specials and Zolfo USGS gauge coming down. I hope to get back to Peace River hunting late next week.

Out hunting today, feeling the burn. Primarily I am trying to get a specific ID on a very small lower horse tooth, It has a protostylid, so not Nannippus aztecus. This is about the smallest that I ever find and so I am hopeful @fossillarry will get a chance to comment. I love lots of comments on any thread, so feel free to pile on.. I was finding other nice stuff... a lot of pretty Sand Tigers, a button denticle, very small canines, it was a good day...lots of mosquitoes and horse flies. It started off with this un_erupted enamel "cap" in the 1st sieve.. I have my thoughts but wait for TFF to ID. And finally , I was REALLY estatic about this earbone attached to a good chunk of skull.. Size is 52 x 38 mm... I am thinking , as it dries that it is modern, but still would love to know which animal creates earbones like these. Two year ago in this same location, I was finding similar earbones...Add here just for reference...

Just trying to finish up finds from yesterday... Here are some knowns, A small Meg I love Sand Tigers with cusps like these!!!! A 7 mm Ray denticle A lower left jaw, p2 tooth from Nannippus aztecus, And now the unknown, As the day moved on, I had already found many nice fossils and sat down on the bank for a drink of water and some grapes. Next to me was a pile of gravel discards... I just can not help searching the discards for a few shark teeth the previous hunter might have missed... I saw an interesting 3-sided bone... Posterior view.. Bottom view... Note the "texture" of this bone.... and another view of the front... Measurements are Length 62 mm, width 38 mm, Height 31 mm. I think it is a hoof core and I hope for confirmation. Going out again in the morning. Leaving Tuesday for a week in Maryland... Thanks all comments/suggestions...

@fossillarry, sorry to do this to you, again. Picked up a bunch of 3-toed teeth for cheap today from the Tampa Bay Fossil fest, and most need an ID. #7 and #10 are from Polk County phosphate mines, and #8 is from Bone Valley (Courtesy of @Family Fun who gave it to me). #11 is from the Peace. The rest I’ve got no clue on. @Shellseeker I know you like 3-toed teeth - I think you’ll enjoy seeing #10. All measurements are in mm, and are width by height of the occlusal surface: 1) 14x12 - C. ingenuum? 2) 15x13 3) 21.5x20.5 4) 16.2x14.2 5) 18x14.5 6) 18x16.4 7) 14x12.4 8) 17.3x16 - N. Aztecus? 9) 18.5x10 - N. Aztecus? 10) 17.4mm long. This was labelled N. minor - which I believe was renamed to N. morgani 11) 26.3mm long. Because of 10, and recently finding out that Equus canines are much bigger than I thought - I wanted to revisit this as a 3-toed canine: Thanks in advance!
