Re: Opisthobranch Fossil History

Dear Bill & Lucas,
I am not volunteering to write about this topic, but I can give some references. In my paper on sacoglossan evolution I have a short paragraph on the fossil record, and I found that Bandel (1988) and Bieler (1992) list acteonid-like fossil shells from the Carboniferous. Haas (1953) illustrates fossils of the more usual "bubble-shell" types (similar to Retusa, Acteocina, etc.) from Upper Triassic. And there are numerous records of fossil opistobranchs from the Tertiary (see f.ex. Valdes & Lozouet, 2000).
