Pennsylvanian gastropod with open coiling at the protoconch.

Recommended Posts

This gastropod was found at Jacksboro Texas in the Finis Shale member of the Graham Formation, Late Pennsylvanian. It resembles some of the smaller species of Pseudozygopleura except for the strongly disjunct coiling near the apex. A steinkern can exhibit similar coiling once the shell and columella are gone but not just at one end and you typically wouldn't see the ornamentation at the anterior end. It is 1.5 mm long.

Very interesting specimen. I have yet to see that unraveling in Palaeozygopleura which is common in the Middle Devonian of central New York. I'll keep my eyes open. Thanks for sharing.

1.5 millimeter?

 

 

Mark.

 

Fossil hunting is easy -- they don't run away when you shoot at them!

Yes! Just think of how easily it could have been completely overlooked! Sometimes I have second looks at my "micro" material just because I usually scan too much of it at once. I don't really have the patience you need for working with them.
