This shell had me confused, as it looks like a big, inflated Quadrula nobilis. Until I saw the interior, that is. It is very different in outline from specimens of A. confragosus found in other parts of Texas, but looks very much like some specimens from the upper Mississippi drainage. It might have been a hitchhiker on a fish that was stocked in Lake Corpus Christi. 118mm
Knobs on beak are alternating like Obliquaria reflexa. I've only seen this on these two species and juvenile specimens of Plectomerus dombeyanus.
Adult sunning in unpaved road lane, pinyon-oak-juniper savanna/open woodland slope with grass in openings and understory.

Collected and to be deposited at Tracy Herbarium; on sandy loam bank of ditch below Quercus stellata.
This moss has visible sporophytes.
Clear, sunny day at 72 degrees.
My first thought was Sharp-shinned, but on reviewing photos some seemed to lean more Cooper's to me, nonetheless the tail is shorter and more square in all photos. And in the 3rd photo you can see the helmet appears to extend to the nape.
