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the 1980s as the M.S. research of D. Govoni, I've led the charge with Dave the past few years to revise and expand his unpublished thesis and ensure that this diverse gastropod fauna received the formal description it deserved. 🧵

If your work involves Big Palaeo Data, you should be *begging* people to publish little local studies of new observational data, jfc. Without that you have absolutely bupkiss. I say this as someone with a foot in both camps:
