Bendix-Almgreen (1966) studied several spiral dentitions of Helicoprion that had cartilage surrounding them. For just over a century, this freaky-looking Permian fish has caused a headache for palaeontologists who have tried to work out what on earth its spiral teeth were. The second problem is with the largest teeth pointing toward the throat the older teeth would hang out of the jaws. To better see the fossils, scientists take X-ray images of the shale slabs—the fossils are a different density than the rock around them, so they stand out in the X-rays, just like your bones do when you get an X-ray of your arm.

From the time of Hay’s paper (1912) until the present, paleontologists have assumed that the tooth whorls of Helicoprion and similar dentitions in other edestoids were jaw dentitions (see Zangerl, 1981:86), but no skeletal evidence existed to support their position. This helicoprion fossil can be found on the mezzanine level of the Keck Museum in case number 62.

The University of Chicago Press, pp.1-347, pl.1-96. Based on whole shark specimens, it appears that tooth replacement was slower in Paleozoic sharks than in living sharks (Williams, 2001). Research suggests that due to the fossils’ locations, the various species of Helicoprion may have lived off the southwestern coast of Gondwana, and later, Pangaea. This week's specimen illustrates a unique feature of this ancient shark species. Its fossils can be found in Russia and in the Western U.S. but no other part of the jaw or shark has ever been found. These have not been found yet associated with Helicoprion, but other edestoid sharks have jaw teeth like these.
