A New Member of the Corystospermaceae Thomas

Untitled

“…It is also noteworthy that relative frequency of terrestrial palynomorphs as well as poor presence of marine palynomorphs leads to the inference that the respective sediments settled in a highly shallow marine environment at the edge of continent. Additionally, regarding resemblance of the identified palynomorphs, conifers and Triassic seed ferns had larger frequency and distribution in the vegetation surrounding the depositional environment of the respective sediments (Townrow, 1965;Taylor, 2009). …”

Bisaccate Pollen of Probable Gnetalean Species and Pollen Diversity in Gnetophytes

“…Dispersed pollen grains of Alisporitestype were found in association with macro remains of the Corystospermaceae. Pollen grains extracted from corysto sper maceous pollen organ Pteruchus were described by Townrow (1962Townrow ( , 1965, Osborn & Taylor (1993), Xuanli et al (1995), and Axsmith et al (2000). The exine ultrastructure of Pteruchus pollen was studied by several authors (Taylor et al 1984: P. dubius; Zavada & Crepet 1985: P. africanus, P. dubius, and P. papillatus; Osborn & Taylor 1993: Pteruchus sp.).…”

“…Anderson & Anderson (2003) identified no further specimens attributable to this species, despite much additional collecting from Thomas's (1933) Gomankov & Meyen 1986, Krassilov et al 1999, Naugolnykh 2013 but has been identified from the Coal Cliff Sandstone in association with Peltaspermum and Lepidopteris (above); this is the youngest known occurrence of Permotheca (Retallack 2002). The Lower Triassic of the Sydney Basin has low plant diversity which was not restored to levels equivalent to that of the Permian until the Middle Triassic (Retallack 1995b Townrow (1965) but, being collected from coal measures, are more likely Carnian-Norian in age (Reid et al 2014). …”
