Florida Miocene Horses

I went out on Saturday, hunting the Peace River.  Did not find very much.  It was one of those days when my hunting partner,  digging 5 feet from me was finding excellent fossils and me , not so much.  I was also feeling out of sorts most of the day,  and that turned into a stomach virus that I am now mostly over.

Add about 150 somewhat bruised small shark teeth, and the hunt was not up to par.  There are always gifts from the river...

I hardly ever find connected ray teeth in the Peace,  This is about 50% of an noncommon find. 

The big lift for the day is that my friend worked in the Phosphate mines in the 1980s and still connects with old friends who did the same.  One has some interesting items and traded some small horse fossils including 20 plus teeth that I got before I started hunting Saturday.  I am truly blessed. :yay-smiley-1:

A few toe fossils

A Medial phalanx L 25 x 22 mm

Another Medial,  L 20 x 16

2023Nov11th_Medial_No1x.thumb.jpg.f8a936e9c62297dff9d8e3a13c872238.jpg

 

Both are too large to be a good fit for this L 29 x 15 mm Proximal phalanx.. Big thrill ,, these are my 1st Horse Phalanx at this size... and the quality is crisp because they were never eroded by water...

Naturally 3 lower right molars, possibly /likely Nannippus

This one has no protostylid , thus N. aztecus APL 14 x width 8 x crown height 27 mm

This one has a protostylid and very small APL 15 x width 10 x crown height 25 mm,  possibly N. westoni

and then this one APL 18 x Width 10 x Crown Height 34 mm.  I can not tell if it has a protostylid or not...and will leave to experts to ID tooth positions...

What is a "protostylid," Jack?  You make it sound useful, but I can't find a good illustration.

My bad,,  I saw the term a couple of years back in a post by @fossillarryhttp://www.thefossilforum.com/topic/110466-horse-tooth/ It applies to lower cheek teeth of Hipparion horses.

It took a couple of years before I discovered it could be used to differentiate between Nannippus species  because Nannippus aztecus teeth do not exhibit a protostylid.

I had flipped the photo to get the ruler correct from Larry's description.  N. westoni is one of the species that has a large protostylid.

An incisor,  I have and do not think Tridactyl, but very small for Equus...

More of the better teeth..

An upper tooth...

These are the most attractive that I've shown, there still are 6 lowers, 10 uppers (2 of which are unerupted)... 

All in all, a significant addition to my collection of Florida small horse teeth.  All comments and corrections greatly appreciated.

Harry, 

Sent the initial 3 Horse teeth to Richard.... Note the 1st line of his response...

Quote
For the horse teeth, some Nannippus aztecus do have a well formed protostylid (about 10%). I think the first are both lower molars of N. aztecus, the first is a left, the second a right. The third one is a right lower premolar that I am not certain about; could be aztecus, could be westoni. Finally, Frank Garcia found a similarly huge Eremotherium claw in the 1990s at Leisey Shell Pit. Have to lay them side-by-side to see which one is larger. We have a cast of the one Frank found in our collection; not sure if he took it with him when he moved out west or if he sold it.
 
Cheers,
Richard

Got some IDs for a few of these teeth...

Finally finished taking photos of all the small horse teeth (16) that have some interest or have a possibility of identification..  I will leave the 1st 6 already added above as is... Here are the other 10 that I will be trying to identify by research  Genus/Species ,  Dental position... Sounds like fun,  but I can always use help....   Thanks Jack
