Wisconsin glaciation

One such claim, proposed by both believers and skeptics, is that this creature was really a pterosaur, a pterodactyl dinosaur, whose long beak may have resembled the snout of a horse.

Cryptozoologists will claim that perhaps this creature may have been driven to Jersey by the movement of the Wisconsin Glacier and could possibly have survived into the age of man, a theory very similar to some about the Loch Ness Monster being a plesiosaur.

While skeptics have suggested that, as has happened with the discovery of other bones, perhaps the skeletal remains of a pterosaur inspired tales of the Jersey Devil, much as it's thought they inspired myths about giants, cyclopses, dragons, and other chimera.

But there is no record of any pterosaur remains ever having been recovered in New Jersey.

They were receding glaciers, right? The glaciers used to cover there because the glaciers came down in some parts of North America, especially where the Great Lakes are.

I think that's the Wisconsin Plate or something like that, the Wisconsin Glacier.

I can't remember what it was.

But like two miles of glacier over the top of the entire Northeastern and Midwestern United States.

Um, the climate cooled again, and a massive glacier spread across the c- the continent during what they actually call the Wisconsin Glaciation Episode.

And near the end of this cycle, about 32,000 years ago, the glacier began its final advance into Wisconsin.

And so now this leads us into Glacial Lake Wisconsin.
