Southern Texas Identification Help

This one was found walking through a shopping mart area with decorative islands of rocks mixed with various fossils like shells and imprints as well as even some petrified pieces of wood. So i know this isn't native to the specific area i found it in.

Gastropod mold fossil. Likely Turritella.

Yep, cross-section along the length of a gastropod (snail).  Did you collect any of the petrified wood?  We'd like to see some picts if you did.
