This is an uncommon prehistoric fossil sea snail shell of the species Triplofusus acmaensis. It was collected by a long time, avid Florida fossil shell collector, in a shell pit in Florida, USA. This specimen was one of his nicest in his collection!
Known for its splendid array of gastropod fossils, Florida is home to many fossil shell species in abundance. The nature of finding a gastropod fossil in a shell pit, for example, usually means that it will be heavily weathered and seriously damaged. Certainly, delicate features of the shell are almost always missing. What is most unique and exciting about this fossil specimen of Triplofusus is that all the anatomy is still intact and well-preserved. The pointed centrum is complete, the labrum (the outer margin of the opening) is undamaged which is very rare, and overall surface detail is wonderfully preserved with no erosion. This complete and very high-grade specimen came from a large sea snail that lived 5 million years ago, crawling around the ocean floor when the massive Megalodon shark still alive, terrorizing the waters off the southeastern Atlantic coast of prehistoric North America.
