The Brightseat gastropod fauna is well suited for transatlantic comparison, and is intermediate in geographic position between other well-studied assemblages including those from the Gulf Coastal Plain, western Greenland, and northwestern Europe.
Incredibly proud to see this project hit the light of day! Begun in the 1980s as the M.S. research of D. Govoni, I've led the charge with Dave the past few years to revise and expand his unpublished thesis and ensure that this diverse gastropod fauna received the formal description it deserved. 🧵
This monograph describes 52 gastropods, including 25 new species/subspecies, from the Brightseat Formation of Maryland, which represents the earliest Paleocene sediments which crop out in this region of the northern Atlantic Coastal Plain.
We find that the Brightseat snails are indicative of overlapping influence from both northern and southern Danian zoogeographic provinces, though its composition appears more closely allied with faunas from Greenland and northwestern Europe.
