Pambdelurion whittingtoni is an extinct, nektonic organism from the Sirius Passet Lagerstätte, from Cambrian Greenland. Its anatomy strongly suggests that it, along with its relative Kerygmachela kierkegaardi, was either an anomalocarid or a close relative thereof. The massive anterior limbs, with their comb-like rows of spines, suggest that P. whittingtoni was a planktivore.
