Mark Doyle (ID registration #57036) was a researcher at the Ibis Island facility. He originally worked in the Special Aircraft Experiment Room before being moved to the Third Energy Physics Laboratory.
He was badly wounded by a velociraptor during their overrun of the base. Regina found him in a room leaning against a desk. Asking him on Dr. Kirk's location, Mark simply responds his view on Kirk as a "fool". He gave Regina his ID card, before succumbing to his injuries. The tyrannosaurus on the island then smashed through the window, dragging his body out.
