Odd shaped bone need ID help

[diginupbones]

First bone I have found with this shape. Found in south central South Dakota. Miocene

[GeschWhat]

Weird.

Maybe the radio-ulna of a camelid?

[fossillarry]

It's an ulna,probably from  a carnivore.

Anyway to narrow this down? Feline, canine etc. @Harry Pristis

It's not horse, it's not bovine, Fossillarry's guess of carnivore ulna is a reasonable one.  Look for a trace of an ulnar tuberosity.  Finding a comparison collection is the best way to ID the ulna.

There are some Early Miocene land mammal localities out there but you'd have to narrow down where you found that.  A friend once told me you need to be careful where you are because there's Native American reservation land out there and you are not allowed to even pick stuff off the ground there.  If it's Early Miocene, it's too early for cat because they didn't migrate to North America until the Middle Miocene - too early for bear too.   That bone might be too big for an Early Miocene dog of the time and area.  Other possibilities of that time would be a nimravid or an amphicyonid.

Thanks for everyone’s input. I know that dogs were common in this area during the Miocene so that may be a good bet. As far as legal issues, no problem there, almost all of my collecting is on private land.

I believe there are Early Miocene ursid bears found across the nation, California to Florida.  These rare critters were called Cephalogale sp. until X. Wang et al. renamed them Phoberogale (P. shareri) in a 2009 paper.  The trigger find was from the Arikareean of the Sespe Formation in the Santa Ana Mtns of California.

 

X. Wang (pers. comm.) also identified some material from my Early Hemingfordian site here in Florida as Phobergale.
