Beast of Dean

The Beast of Dean is an animal said to live, or to have once lived, in the Forest of Dean, Gloucestershire, England.
History.
Farmers from the village of Parkend undertook an expedition to capture and kill the creature, in 1802 but found nothing. The animal they were hunting was reported to be a boar large enough to fell trees and hedges.
In fiction.
In the science-fiction television series "Primeval", the Beast of Dean turns out to be a gorgonopsid that arrived in the present day through a wormhole leading to the Permian period.
