Crucella jadeae
Named by Carter & Dumitrica.
Original description: Test flat with long and narrow rays; rays increasing very slowly in width distally and terminating in more or less expanded tips. Each ray with a three-bladed, pointed distal spine the length of which is about half the length of ray. Central area flat, small. Surface of rays and central area with small, dense, irregularly arranged pores. Sides of rays vertical to slightly concave.
Original remarks: As written by Yeh (1987b) this form differs from Pseudocrucella magna Blome (1984b) by having rays with expanded tips and with less massive spines. Crucella jadeae is very close to the Sinemurian species C. kaisunensis Whalen & Carter but differs in having longer arms and mostly triradiate rather than circular spines.
Etymology: The species is named for Kuei-Yu Yeh (Jade) who illustrated the first specimens.
