1969 Pachypteris austropapillosa Douglas , figs. 25– 27.

2002 Pachydermophyllum austropapillosum (Douglas, 1969) McLoughlin and Nagalingum fig. 39.

Material. Little Beach-03: LX1014, The Chasm: LX0658, LX0659.

Description. Frond pinnate, elliptical in overall outline, with longest pinnules in the middle,> 50 mm long. Rachis prominent, with central ridge/depression. Pinnules 12–13 mm long, 2.3–3.8 mm wide, well-spaced, about 2.3–2.5 mm, attached laterally, at near right angles (c. 70–90°), connected by a narrow flange along the rachis, mostly straight, basiscopic margins prominently decurrent, acroscopic margins curving basally, margins roughly parallel, but crenulate, one central vein.

Remarks. Fronds at The Chasm are similar to Victorian Early Cretaceous material that Douglas (1969) placed in a new species, Pachypteris austropapillosa and which was later transferred to Pachydermophyllum by McLoughlin et al. (2002). Similar material (as Pachypteris ) has also been listed in the Walloon Coal Measures (Gould, 1974, 1975, 1980; P. pinnata , P. cf. austropapillosa , P. crassa ).
