Uncle Siphuncle Posted September 4, 2007 Share Posted September 4, 2007 Another Texas terrace deposit find, I hope to learn to distinguish between bison and camel astragali with the aid of your responses to this thread. I know this specimen is not cow as there was gravel cemented to it as found. I left the matrix in place as a sort of Pleistocene "proof seal" since some of our Pleistocene stuff is hard to date by color or degree of mineralization. Grüße, Daniel A.

Gatorman Posted September 4, 2007 Share Posted September 4, 2007 I'm going to guess Camel i have one seemingly identical to it only from the opposite side. and slightly smaller Link to comment Share on other sites More sharing options...

auraman Posted July 23, 2011 Share Posted July 23, 2011 Here is a pair of Astragalus which I am two members of Houston Gem & Mineral Society collected recently. I think they belong to the same bison as one is right and the other is left. They articulate about 80 to 85 degrees (not quite a 90 degree bend). We collected 15 bison teeth and about 50 to 100 other bones, including 12 leg bones in the same dig. The Astragalus were neat because each would rotate, i.e. the convex side in the concave side showing a perfet fit. Thought you might like to see this pair. 1 Link to comment Share on other sites More sharing options...

Tell us what we're looking at in your image. They don't appear to be astragalus/calcaneum articulations. Is that a pair of astragali articulating with the distal ends of tibias? Here's how that articulation looks in an equine horse: 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
