RARE ACANTHODES SPINY SHARK FROM THE PERMIAN WITH EXCELLENT PRESERVATION Niederkirchen, Germany EARLY PERMIAN PERIOD: 290 million years ago With classic white fossilized remains known for this location, this Acanthodes species spiny shark exhibits a rare form of Permian fossilization from the famous Permian "Red Beds" of Southwestern Germany. Seldom found complete and in such fine preservation, this rare Paleozoic fish is well displayed on its original shale matrix. This beautiful rock slab features a remarkably well-preserved Acanthodes in an aesthetic "dancing" pose. The shark is well-centered on the slab and displays a rare white fossilized body impression with spines. Contrasting wonderfully is its original host rock slab with dark olive green and gray tones to set off the white fossil making for an aesthetic display. This is a rare fossil and in much better than usually found preservation. It is highly recommended for an advanced collection or a public exhibit since fine quality specimens of this creature are very hard to come by. Minor restoration on interior body regions only. Acanthodes are an extinct genus of primitive fish also called "spiny sharks". Acanthodes fossils have been found as far back as the Silurian Period, 440 million years ago, and are classified as bony fish but share several similarities with sharks. They continue to confound scientists as to their evolutionary beginnings and endings. They are identified by prominent spines on their pectoral fins and their anterior-situated dorsal fin. These spines were believed to for protection from predators. As they lacked teeth in their jaws, it is believed they were filter-feeders living primarily on plankton.
