large cat medial phalanx

[thefossilkid]

I recently got this large cat medial phalanx, the info I got along with it isn't the most trust worthy, so I'm just looking to get other opinions from more experienced folks. The info I got is as follows,

 

hometherium serum medial phalanx, st Mary's river. Pleistocene. 

 

I know it's from a large cat, either jaguar or smilodon/hometherium. Any opinions would be appreciated.

 

I'm only about to upload one picture at a time, so I will reply with more pictures.

 

It measures 1.48" long.

It's a big cat, no doubt.  Which one, I don't know.  What's interesting is the reported find locale -- the St. Mary's River.  I've explored that river a little a long time ago.  Upstream of the US 17 bridge, I remember deep sand -- hopeless for finding fossils.  Downstream of US 17, the bottom was swept clean by strong tides.  Lots of Middle Miocene marine fossils there along the outside of the river bends -- megalodons, whale, and smaller shark teeth.  This is a true blackwater dive with NO visibility and a swift current, not for the faint of heart!!  I am surprised to see a Pleistocene cat fossil from that river.

I appreciate the reply, that's what was written in the I.d card, but that can be taken with a grain of salt, it could have easily been found elsewhere. No one to know for sure unless you find it yourself!

Here are some pictures of a smilodon fatalis medial phalanx, it looks nearly identicle to mine when comparing features. Interesting for sure!
