Jiesen Posted May 2 Share Posted May 2 Any thoughts on this? I know it's a stab in the dark, due to the small partial remnant. This is embedded in a large landscaping stone that was quarried in South Central TX, USA, almost certainly between San Antonio and Austin. So it's Cretaceous, for sure. It measures about 60 mm in length (house key for additional scale). What you see here is all that's visible, unfortunately. I appreciate the feedback!

Mark Kmiecik Posted May 2 Share Posted May 2 (edited) Judging by size and surface ornamentation, I would guess that it's a fragment of Texigryphaea mucronata, quite common in the lower Cretaceous of Texas. However, I'm not an expert in the fossils of Texas, so let's let a few others chime in before we accept this ID. Edited May 2 by Mark Kmiecik fix typo 1 Mark.
