Other claims from this paper (13)
- Observation Early Permian plant assemblages in north-central Texas are dominated by seed plants.
- Observation Ullmannia occurs in the Early Permian flora and is known from the Late Permian Zechstein flora of Germany and England.
- Observation Pseudovoltzia liebeana occurs in the Early Permian flora and is known from the Late Permian Zechstein flora of Germany and England.
- Observation Podozamites sp. is characteristic of the Mesozoic.
- Observation Walchia sp. is abundant in Early Permian floras.
- Observation Taeniopteris cf. eckardtii is locally common and is a Zechstein species.
- Observation Dioonitocarpidium, a presumed cycad megasporophyll, is known only from the Mesozoic.
- Observation Dicranophyllum leaf fragments are rarely encountered and belong to a Paleozoic ginkgophyte.
- Observation Wattia is typical of the Early Permian.
- Observation Some seeds in the Early Permian assemblage are remarkably similar to Agathis and of Cretaceous age.
- Observation Derived lineages in xeric habitats during the Early Permian indicate that some supposed Mesozoic groups preceded and survived the end-Permian extinction.
- Observation Only rare scraps of foliage and seeds are attributable to pteridophyllous elements in the assemblage.
- Observation The fossil plants occur in multistorey, fining-upwards, tidal-channel deposits.
