It also highlights the possibility that the Carnian Pluvial Event, although most likely triggered by enhanced volcanic activity, may also have been modified by an orbital stimulus. ..."

Thus, referring to the Triassic as warm and the Jurassic as wet is an oversimplification of the geological evidence and palaeoclimate model simulations. ..."

N. Zavialova (2024): Comment on “The ‘seed-fern’ Lepidopteris mass-produced the abnormal pollen Ricciisporites during the end-Triassic biotic crisis” by V. Vajda, S. McLoughlin, S. M. Slater, O. Gustafsson, and A. G. Rasmusson [Palaeogeography, Palaeoclimatology, Palaeoecology, 627 (2023), 111,723]. Abstract, Review of Palaeobotany and Palynology, 322.
"... Recently, Ricciisporites Lundblad and Cycadopites Wodehouse (= Monosulcites Cookson) pollen types have been found cooccurring in Antevsia zeilleri
[...] the two pollen types are too dissimilar by their exine ultrastructure as well as by the general morphology and exine sculpture.
[...] Another explanation should be found for the presence of Ricciisporites tetrads in these pollen sacs ..."
