So when I first dug this up out of the sand, I thought it was probably modern due to the color, and it felt pretty light and a little more brittle than my normal finds. But there is mostly Pleistocene material here and sometimes it can be hard to tell. I put a lighter under it and it had no reaction. And when I cleaned it up, I realized that a hole runs through it. I've read a lot of past posts by @Harry Pristis describing foramen, and I've seen examples in his collections where he discusses the differences between which animals have which types of foramen, but I'm still a little shaky on telling whether this would be an entepicondylar or supracondylar foramen. I thought that foramen for leg bones are only found in the distal humerus, but this bone has a particularly flat end that doesn't seem like a great match for the humerus examples I've looked at so far. Maybe that's just due to wear. I feel like I'm probably missing something here. Any info would help. Thanks. --Brandy

Hello, I found this joint end of a bone in a spoil pile. It has nice brown color and it is NOT dense. Underside shows fibrous area. I have found Equus and whale bone, and deer antler in this area as well as Meg teeth. I read Hulbert's book and my speculation was a ankle bone of some type or phalange. I can see where it might be from a piece of humerus. fossil is 3 cm high and 4 cm wide. Assistance appreciated. - Michael

Some years ago I found this among the red rocks just beyond Zion National Park. I thought it was a stone with erosion and wore it around my neck until someone told me it was a petrified bone. I took it to a place in NYC that specializes in fossils and they told me to go to the Museum of Natural History because they could not identify it but definitely thought it was something. I thought I should let you guys take a crack at it. Photos are of two sides with the second side showing a distinct darkness around the putative foramen. I have additional photos. I am new at this and appreciate any insights or thoughts. Thank-you! Dimensions: Length: 3.25" (8.5 cm) Width: 1.25" (3.0 cm) Thickness: 0.25" (app. 0.5 cm) Foramen: 0.25" (app. 0.5cm)
