Pustulatia pustulosa from the Kashong Shale

Pustulatia pustulosa is a new brachiopod species for me. I found about a dozen specimens in the Kashong shale near Greigsville, NY on a recent trip. It's a small shell and one that I initially thought might be a growth stage for Tropidoleptus (due to the plications) but, as you can see in the profile picture below, it's brachial valve is convex rather then concave.

This shell has some small bryozoan epibonts on it but I have not yet determined their name yet.
