I was diving a couple of days ago and found this interesting bone, which I believe to be some sort of digit or toe bone. The most interesting characteristic, which I think is on the proximal surface, is the deep articulating crease. The distal portion has two small prominences. I am going to include side view and an oblique view (showing the alignment of both the distal and proximal surfaces). Any ideas to this Pleistocene mammal (I’m guessing at the age, but older deposits in the river are all marine)
The distal, proximal, and lateral views make me think that it’s a distal phalange. As i’ve been looking at Gomphothere phalanges the past few weeks, and by the size of it, it may be elephant. I’ll compare it to some of the text we have in the office and check out the collections. This looks pretty cool! Great job Lee!
