GIANT LEFT-COILING SEA SNAIL SHELL WITH LARGE INTERNAL WORM CASING Sarasota County, Florida, U.S.A. PLIOCENE TO PLEISTOCENE PERIOD: 5 million - 10,000 years ago 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 particular specimen of Sinistrofulgur contrarium is that the shell is complete and intact.... and HUGE!!! One additional feature of this choice specimen is the complete three-dimensional worm borer casing still attached and perfectly preserved inside this giant shell opening. The entire casing is fossilized into stone and the detail as seen above is nothing short of sheer beauty and fascination as the outer structure of the casing is extremely globular and complex. Even the entry hole the worm borer made is still present and undamaged with a calcareous deposit to one side as the borer attached itself to this massive gastropod prior to entry inside the shell. The internal luster and nacre are even still present in this complete giant fossil shell! The external anatomy is highly detailed and exceptionally preserved with the thin opening intact. This remarkable gastropod fossil is not only rare for its condition but it makes for a highly aesthetic display specimen due to its exceptionally large size. The large, intact worm casing is the 'cherry on top' to this prize specimen and sets it in a class all its own! Guaranteed NO REPAIR and NO RESTORATION.Sinistrofulgur contrarium is a member of a unique sub-genus Sinistrofulgur of left-coiling snails. This animal lived during the Pliocene / Pleistocene Period and was a predatory marine creature that fed mainly on bivalves by attaching itself to its prey with its foot and slowly rasping a hole in the shell of its unfortunate victim. Sinistrofulgur could move great distances and can go against tidal currents with the use of its powerful foot. If you want a very high-grade and stunning prehistoric sea snail fossil, we highly recommend this example. This sea snail was alive during the last Ice Age in North America when many gigantic and bizarre beasts walked the earth and swam in the oceans including the last days of the giant Megalodon shark!
