Mark A. Hall presented reports of Thunderbirds and other mysterious creatures.One cryptoid he's studied is the "Lizardman"-- a 7 ft. tall scaly creature that was reportedly seen in South Carolina in 1988. Hall related the Lizardman to folkloric tales of mermen and mermaids, who were said to inhabit the water yet be able to remove their fish parts like scuba gear when they came on land and sometimes mated with humans.

In the Yukon Territory and Alaska, there are modern day reports of Neanderthals seen wearing crude clothing and carrying axes, said Hall.

Thunderbirds, with a serrated beak and a 15 to 25 ft. wingspan, were likely more plentiful in America in centuries past, when there was a larger supply of bison, he noted. Hall suggested that these birds could be related to Teratornis, a huge predator from the Pleistocene era. He also shared reports of giant owls, snakes and bats.
