During the Ice Age, a wolf pup in an area that would one day be called northeastern Siberia ate a woolly rhinoceros, then died shortly after. About 14,400 years later, the mummified body of that pup was discovered in the permafrost, its last meal still in its stomach. Researchers sequenced the complete genome of this extinct species of rhinoceros from the sample found in the wolf, making scientific history in the process.
