The skull’s presence was not voluntary, as it is believed to have washed into the cave during the last ice age. Now, a replica adorns the visitors’ center, serving as a “jewel in the crown” of Stump Cross’s 300-million-year narrative. This discovery, along with other recent finds, enriches our understanding of Yorkshire’s deep history.
