his own private stock at a place called Woolly Cove

Satire. Come on now, people have been writing amusing fictions and publishing them with a nudge and a wink for longer than the internet has been around :)

edit: here's a blurb from the Wikipedia on woolly mammoth which leads to a citation here but I am not familiar enough with Wikipedia to track that down to an actual book:

Stories abound about frozen woolly mammoth meat that was consumed once defrosted, especially that of the "Berezovka mammoth", but most of these are considered dubious. The carcasses were in most cases decayed, and the stench so unbearable that only wild scavengers and the dogs accompanying the finders showed any interest in the flesh. It appears that such meat was once recommended against illness in China, and Siberian natives have occasionally cooked the meat of frozen carcasses they discovered.

edit#2: Also, mentalfloss is just like cracked.com, insofar as it is almost completely or completely unresearched and written purely for entertainment value, so take it for what it is, I guess :)
