Triassic
Gondwanan floral assemblages reflect paleogeography more than geologic time. Abstract,
Gondwana Research.
"... Combining these and existing geochronologic data with a newly assembled comprehensive
presence/absence dataset of palynomorphs from the Anisian-Norian of Gondwana, we demonstrate
that paleogeography (paleolatitude) has a significantly stronger correlation with taxonomic
composition of assemblages than does geologic time
[...] results imply that geography is an important null hypothesis in explaining differences
in early Mesozoic Gondwanan palynomorph assemblages, and that precise geochronologic age
constraints are important for refining the accuracy of Triassic palynomorph biochronology ..."

Figure 6: General facies model of the SMK [the Norian Steinmergel-Keuper].
"... The Norian Steinmergel.Keuper (SMK) represents a low-latitude cyclically-bedded playa system of
the Mid-German Basin.
[...] Dolomite layers reflect the lake stage (maximum monsoon) while red mudstones indicate the dry phase (minimum monsoon) of the
playa cycle.
[...] humid periods reveal thick layers of dolomite beds, indicating that
during those intervals the monsoonal activity was strong enough to prevent the playa system from
drying out completely.
