Columbellidae was the most representative family in terms of species number (6), followed by Pyramidellidae
(4), Fissurellidae (3), and Muricidae (3).
POTAMIDIDAE Cerithidea mazatlanica PSEUDOLIVIDAE Macron aethiops PYRAMIDELLIDAE
Marine micro-molluscan fauna known from within 20 km of Shelly Beach include members of the Anabathridae, Anatomidae, Pyramidellidae
, Rissoidae and Skeneidae (Australian Museum data).
As a trained taxonomist, his collaborations resulted in over 20 international articles related to modern and fossil gastropods, culminating in a reorganization of the pyramidellidae
. Most paleontologists specialize in a particular taxonomic group or period of Earth history, but demonstrating his versatility as a paleontologist and recognizing the lack of study in Tennessee, Corgan parlayed his highly varied interests into a long list of contributions to Tennessee paleontology spanning many taxonomic groups.
The nomenclature and phylogenetic position of the Pyramidellidae
Moreover, Hoisaeter (1998) listed 252 species of shelled gastropods hand collected from intertidal to 8m depth in Golfo Dulce (Pacific, Costa Rica), with 14 species in the Vitrinellidae and 13 in the Pyramidellidae
, and the genus Turbonilla alone represented by 13 species.

Corgan's focus as a gastropods taxonomist resulted over 20 collaborated international articles related to modern and fossil gastropods, culminating in a reorganization of the pyramidellidae
. Demonstrating his versatility as a paleontologist, Corgan parlayed his interest in vertebrates culminated in two editions of a compendium volume Vertebrates of Tennessee.
