Ohio State - Clemson,

 

You are too nice not to be a Buckeye. Congratulations to those who are Clemson fans. Good game. To Ohio State fans, OH....

 

 By the way, GREAT finds. All three are neat!!

First one’s a Carcharhinus.

Can't help you on the id questions, but they sure are cool finds. I particularly like that shark tooth.

Thanks for putting some pics up Jack maybe @Harry Pristis can shed some light

Great finds, especially #1.  Love the color and completeness.

Item 2 appears to be an isolated lacuna from a bovid tooth.

Item 3 might be a senile tapir tooth.

Thank you Mike,  My better half graduated from Clemson, which means I get to watch every Clemson football game in its entirety, independent of score. She is what you might call a fan...atic..  These are stressful times in my household..  Jack

Well, I am pretty familiar with the most common Florida fossil shark teeth, and if I were to do a WAG,  just based on appearance,  which I do understand is completely unscientific ()  , I would tend to think , this pathological one looks mostly like two lower dusky (c. obscurus) teeth mashed together, and Dusky/Bull tend to be the most common shark tooth (along with Lemon) found in my hunting grounds. 

 

Thanks for the ID I am real pleased with the tooth.

Your photos confirm tapir.  On the "isolated lacuna", I was kind of amazed. At first I thought the roots, were the un_erupted occlusal surface, but I did not recognize the roots as similar to anything I had seen. And I do not imagine that there are many "Isolated lacunas"  out in the fossil world.  I do not think it is broken, although the encrustation hides a lot.

 

I think it is one for the cabinet case for our friend @jcbshark, even when it it not possible to ID below the level of 'bovid' .  Thanks for the IDs

I don't understand.  Are you rejecting the lacuna identification?  I think that there are many, many isolated lacunae out in the fossil world.  It's just that exceedingly few get picked up and examined.  On TFF we more often see vertical slivers of horse teeth, I suppose because horse teeth are much more common than bison teeth in Florida.

I think it’s a split-crown tooth. The root has one nutrient groove and doesn’t seem distorted.

 

By the way, I took your recommendation of the 1/4” woven mesh screen from Pegasus. It seems very durable and works perfectly. Thanks for showing me that company.

Absolutely not.. It is bovid, it is a lacuna.

My focus is how this specific fossil was formed. It is partially covered with matrix that seems impossible to remove without breakage. Outside of that , it seems to be intact, no breakage, and minimal erosion from water or sand.

Every other "Isolated" lacuna I have ever seen fossil hunting, fossil shows, fossil research, was isolated by breaking or wearing off the rest of the normally identifiable molar.

It would be like finding a single Mastodont loph in high quality preservation and no indications of damage. I also wonder of it is mostly or entirely enamel.

Agree that there are surprises in the fossil world, which is why my thought here are possibilities, rather than probabilities.

Agree - split-crown,

I love woven mesh. I "fit" sieve size to screen size. No sharp edges to prick my fingers and it Lastsssssssssssssssssss....
