Trilobita - Proetida - Phillipsiidae

Taxonomy
Carbonocoryphe planucauda was named by Brezinski (1998) [= Griffithidella depressus var. depressus HESSLER, 1965, pl. 38, figs. 2, 3, 5, 9 (not figs. 1, 4).]. Its type specimen is CM 35785, a pygidium, and it is a 3D body fossil.

It was recombined as Phillibole planucauda by Brezinski (2000).

Diagnosis
ReferenceDiagnosis
D. K. Brezinski 1998Pygidium flattened, smooth, axial rings flat and narrow, ring furrows shallow. Axis conical in outline. Border broadens posteriorly with extensions of the pleural bands present behind axial terminus.

Pygidium outline semicircular, relief and vaulting very low. Axis less strongly tapering posteriorly, rounded in transverse profile, gently descending, straight in longitudinal profile, acutely rounded at terminus, composed of 12 to 13 rings. Rings smooth, flattened, broad (longitudinal); ring furrows shallow, narrow, straight. Pleural fields mildly convex in transverse profile, flat adjacent to dorsal furrow, composed of 9 to 10 ribs which extend behind axial terminus. Ribs composed of two bands of near equal width; anterior band lower than posterior band. Posterior band extends onto border and becomes recurved on posterior ribs. Interpleural furrows narrow, distinct on anterior ribs, becoming indistinct posteriorly; pleural furrows broader, deeper than interpleural furrows. Border indistinct, gently inclined to margin in front, becoming broader, less steeply sloping behind axial terminus, exhibits faint extensions of the pleural ribs, rounded at margin
