1901: Russian scientists were excited by the discovery of a mammoth, frozen into a cliff above a remote Siberian river. Otto Herz, a zoologist, and Eugen Pfizenmayer, a taxidermist, were sent to excavate the carcass and transport it to St. Petersburg. Herz noted that the mammoth’s flesh, refrigerated for thousands of years, was dark red and marbled and looked like fresh beef. “We wondered for some time whether we should not taste it.” They didn’t, but they did feed bits to their dogs, who lived to tell the tale.
