Plant-insect interactions are among the most common biotic relationships, both in diversity
and abundance. The fossil record reflects these associations as damage traces on the …

Abstract The Puesto Viejo Group crops out in the San Rafael Block, southwest Mendoza, at
approximately 35° S and 68° 20′ W. It consists of the basal mainly grayish Quebrada de los …

Triassic continental sedimentation in Southern South America is related to the Gondwanides
orogenesis directly. There were two distinct phases of sedimentation,(1) the wide alluvial …

Abstract The Late Triassic represents records many of the most critical biotic crises in life-
history (from Carnian to the end-Triassic extinction, ETE). Some hypotheses propose that …

A synergistic model based on reciprocal influences between biotic and abiotic factors is
developed for the Triassic of southwestern Gondwana. Changes in physical environment …

Studies on ichnofabrics have focused mainly on marine environments. Attempts to apply the
ichnofabric methodology and theoretical framework to continental deposits bearing …

Three new species of Dicroidium, D. irnensis, D. jordanensis and D. robustum, are
described from the Um Irna Formation (Upper Permian) of the Dead Sea region, Jordan. The …

Fossil plants are reported from beds exposed on northern Nelson Island, South Shetland
Islands. The fossiliferous beds are exposed near sea level and constitute the basal intervals …

In this study we describe and compare the palynological assemblages from the Carnian
Ischigualasto Formation of westernmost Gondwana to those of eastern Gondwana, which …

Abstract The Ischigualasto Formation was deposited in a fluvial system and contains a very
well preserved Triassic flora. This flora comprises seven taphofacies:(1) C (St) …
