Miocene Canine teeth from Florida

[BMoore]

A question for fossil mammal collectors in Florida.

 

On a popular auction site I see Miocene canine teeth (canine and pre-molars) from Florida  listed as "Bear Dog". By bear dog I would assume a Amphicyonid. But the species is listed as Desmocyon matthewi, a Borophaginae. From the Wang book (Dogs), the Amphicyonids are now thought to be closer to Ursids (bears). 

 

Is "Bear Dog"  used as a generic term for Miocene fossils dogs in Florida?  Any references to Miocene dogs in Florida?

 

Thanks.

No, bear dogs are amphicyonids.

 

Desmocyon is a borophagine dog.

 

Osbornodon is an hesperocyonine dog.

 

Wang doesn't even compare Desmocyon to the amphicyonids from the Miller Site.  He does compare Osbornodon to Desmocyon, both from that site.  Desmocyon is a rather small dog -- I'd guess about the size of a Jack Russell terrier -- a far cry from the contemporary amphicyonids.

Thank you. 

So Desmocyon teeth will be roughly the same size as Hesperocyon teeth, though perhaps a bit heavier?  Also I assume the bone does not preserve well in the humid environment. The Hesperocyon teeth from the west always seem to be embedded in jaw bone.
