Rectangular holococcoliths with distinct lateral and end rim blocks and a large central pore. In side view it has a box-like appearance that tapers slightly to one end where it is capped by a cover.
Medium to large sized holococcolith seen in side view and comprising a basal coccolith formed from two plates, the upper of which extends distally to form a tall process that tapers to a termination capped by a distal cover. The spine is taller than the maximum width of the coccolith.
Medium sized holococcolith comprising several distinct crystallographic blocks that change appearance on rotation in XPL. At 0° six blocks are visible, four major quadrants, alternating dark and light, delineated by axial sutures, and one small block at each end. At 5° the four quadrants are bright and a small pore is visible in the centre. At 45° the coccolith is bright and crossed by diagonal extinction lines.
Small holococccolith with small blocks at either end and two relatively large longitundinal central area holes.
Similar to L. duocavus but without perforations in the plates
Medium sized holococcolith comprising several distinct crystallographic blocks. At 0° four blocks are visible, four major quadrants demarcated by dark extinction lines. There is a small pore visible at the centre of the coccolith.
Small, elliptical holococcoliths with two small blocks at either end of the lith and a circular central hole or depression, which is dark in XPL. In XPL, the blocks are relatively dark when the coccolith is orientated at 0° and brightest at 45°.
Small holoccolith with 4-6 rim blocks surrounding a central block
Specimens which cannot be assigned to any established species
