A lone, sick ape wonders onto the streets of Edmonton, Alberta. Not only is he sick and alone, but he is also sad. He is the last of his kind. Gigantopitchecus blacki, the biggest ape to ever live. This species stood at ten feet and weighed 650 pounds. It was a land dwelling ape, built like a gorilla. It is possible that some Gigantopithecus crossed over to North America via the Bering land bridge during the last Ice Age. We really don't know what went east or west.
The lone male continued his trek through the streets of Edmonton, searching for, something. Maybe a mate or other members of his species. Unknown to him, almost all of the species is extinct. He eventually comes to a big tree in a small park. Weak and tired from his journey, Gigantopithecus lays down to sleep.
The next morning, two middle school students discovered a large ape carcass in Nellie McClung park, of which they reported to local authorities. At first police thought that it was an escaped gorilla from a zoo. However, after further examination of the corpse, it was determined to be an unidentifiable species of hominid (ape).
The University of Alberta paleontology department was contacted. A professor examined the body and determined to be that of the long-thought-to-be-extinct species, Gigantopithecus blacki.
Over the next few months, more carcasses and skeletons began turning up around Canada, Alaska, and the northern US. Paleontologists from across North America were able to determine that some groups of the giant ape must have migrated to North America during the last Ice Age.
Paleontologists and authorities from the areas of which Gigantopithecus fossils has been found (India, Pakistan and China) were contacted to see if they had any living members of the great ape. None turned up, unfortunately.
At a televised UN conservation conference later in October, the Gigantopithecus was declared a newly extinct species. It was all over. The search for big foot/Sasquatch. All over.
