Linguaphillipsia cangonensis Engel & Morris 1975

1975 Linguaphillipsia cangonensis Engel & Morris ; p. 160–164, pl. 1, figs. 5–8.

Holotype. AMF80211 (external mould of pygidium).

Paratype material. From NU L415: AMF80205 (internal librigena), AMF80206 (external librigena), AMF80207 (external pygidium), AMF80208 (internal pygidium). From NU L506: AMF80209 (external cranidium), AMF80210 (external pygidium), AMF80212 (external pygidium), AMF80213 (external cephalon), AMF80214 (internal pygidium), SMF 27575, SMF 27576, SMF 27577.

Locality. Type—NU L506. Other—NU L415.

Emended diagnosis. Glabella low and broad, extending onto the wide anterior border; central section of glabella vaulted, moderately constricted at γ; palpebral lobes long, posteriorly placed; short divergent ε – ζ section; eyes large. Pygidium parabolic to sub-circular, with 17 axial rings and 12–13 pleural ribs; wide pygidial border, flat to gently convex; weak border furrow.

Remarks. Linguaphillipsia cangonensis is considered to have similar pygidial features to L. terapaiensis , but has distinctly different cephalic features. These included a very broad cephalic border and a broader glabella, which is shorter anteriorly from L3. Similarities to other Australian Linguaphillipsia include a short, straight, divergent ε – ζ section and eye platform characters (Engel & Morris 1975). The original diagnosis was emended to remove descriptions of juvenile facial sutures, and the description that the mid-section of the glabella expands forward, which cannot be seen on the specimens available.
