Pannaulika triassica is a prehistoric plant species described in 1993 on the basis of a small, incomplete leaf and two "flowers".

[4] The incomplete, dicot-like leaf fragment, measuring 32 mm in length, has a vein structure which suggested to the original describer, Bruce Cornet, that the plant was an angiosperm, although it also shared some characteristics with ferns.

[3][5] In 1996, it was noted that although assignment to the angiosperms could be doubted, the looping vein pattern was angiosperm-like and different from that of Dictyophyllum, a fern in the family Dipteridaceae, which has a somewhat similar venation.

[6] In 2001, the discovery of a relatively complete specimen of Pannaulika triassica from the same quarry was reported at a Geological Society of America conference.

The authors of the conference report said that the new specimen indicates a relationship with Clathropteris, which is a fern in the family Dipteridaceae, suggesting that P. triassica is not an angiosperm.
