Karpinsky often commented that “the geologist needs the whole Earth” — he was at the forefront of promoting the notion that any interpretation of the geological structure of the Earth requires a global outlook. In 1898, Karpinsky became involved in an unusual paleontological diversion, a puzzle that still intrigues geologists today. A school inspector exploring the Ural Mountains encountered a strange fossil in some Permian strata. Whorl- shaped like an ammonite, it was clearly an arrangement of shark’s teeth. A photograph and description were sent to Karpinsky for his comments. He named it Helicoprion (from the Greek helico, “spiral,” and prion, “saw”) and suggested that it initially protruded from the snout of the shark. Admittedly, this seems unlikely, so in subsequent interpretations, he decided the apparatus were not teeth, but rather defensive spines either on the tail or dorsal region of the shark. Helicoprion fossils have been found in some other locations outside of Russia and have puzzled paleontologists for over 100 years. It appears they are indeed teeth, a kind of circular saw in the mouth. However, because of how the teeth grow, only a portion of the whorl, with just a dozen or so teeth, would have been exposed at any time. Karpinsky passed away in 1936. His ashes were placed within the Kremlin Wall in Moscow, a mark of the great esteem with which he was held for his contributions, not only to geological science, but to the location of mineral resources that helped develop the Russian economy. A number of geographic features carry his name, as does the Russian Geological Institute (VESGEI). VESGEI is the successor and custodian of traditions of the first state geological institution in Russia, the Geological Committee. Effectively the state geological survey, it was established in Saint Petersburg in 1882, by a decree of Emperor Alexander III (with guidance from Karpinsky) to study the geology of Russia. This included the compilation of a geological map of all Russian territories, as well as investigating the prospectivity of the country’s regions for different mineral resources. Karpinsky was the first to chair this committee and the fact that its successor institute now carries his name is a fitting tribute to the great pioneer of Russian geology.
