---|---|---|
J.L. Wilson 1954 | The size range of the specimens (all from a single boulder) is from 5 to 10 mm. long. Almost half the cranidial length is formed by the border which is prolonged into a convex blunt spine. This is counter-balanced by a large thick occipital spine of about equal size although this is broken off all but one specimen. The test is finely tuberculate. The free cheek possesses a triangular ocular platform, steeply depressed laterally, a wellmarked marginal furrow and a relatively wide, moderately convex border. Presumably the anterior facial suture cuts the margin of the cranidium a t some place along the side of the cranidial spine. |
