Periwinkle Paleontologists

Marine gastropods explore nooks and crannies formed from the remains of their ancient relatives. At a snail's pace, this modern periwinkle clan traverses casts and molds of bivalve brethren that occupied a nearby shoreline once upon a time... 

Limestone formations in eastern North Carolina often contain molluscan casts and molds formed from ancient sea life deposited eons ago. Between them, the gastropods and bivalves account for some 50,000 extant species in both marine and freshwater ecosystems today.  Long live the mollusks!
