Auspex Posted July 31, 2014 Share Posted July 31, 2014 The annular rings look a bit tusky...I can't make out any Schrager lines, though.

calhounensis Posted July 31, 2014 Share Posted July 31, 2014 (edited) Sirenian rib fragment, probably Metaxytherium crataegense if you're finding Miocene material. Those annular rings Auspex referred to are commonly seen in sirenian ribs. Edited July 31, 2014 by calhounensis Link to comment Share on other sites More sharing options...

Badger33 Posted August 1, 2014 Author Share Posted August 1, 2014 Thanks for the responses. That is what I was leaning towards after seeing simialr posts on this forum. At first I thought it resembled a walrus tusk or whale tooth. However, the concentric lines did not extend into the core like Sperm Whale Teeth. And the cross-section seemed to lack the more porous inner dentine of Walrus tusk that is typically finely compacted with a mottled appearance .......characterized as having a "marbled or oatmeal-like" appearance by Espinoza and Mann (1992, p.14). The concentric growth rings and iridescent mineralization (in places visible with hand lens) were throwing me off, but apparently these growth rings are typical for Sirenian ribs.
