THE SYSTEMATIC POSITION OF THE IPSVICIIDAE (UPPER TRIASSIC HEMIPTERA) AND SOME NEW UPPER PERMIAN AND MIDDLE TRIASSIC HEMIPTERA FROM AUSTRALIA (INSECTA)

Algae (Dasycladales) from the Upper Triassic Nayband Formation (northeast Iran)

Dasycladales are relatively abundant in the bedded limestones of the Bidestan and Howz-e Khan members of the Late Triassic Nayband Formation in central Iran. In a locality south of the town of Naybandan (northwest of Dig-e Rostam), several Rhaetian dasycladacean algae were found in thin sections. The following taxa are described: Diplopora phanerospora Pia, Naybandoporella rhaetica nov. gen. no...

Upper Triassic Tetrapods from the Lucero Uplift, Central New Mexico

Six localities in the lower Chinle Group of central New Mexico yield a tetrapod fauna consisting of the diminutive metoposaurid cf. Apachesaurus sp., and indeterminate large metoposaurids (probably Buettneria sp.), the phytosaur Rutiodon sp., indeterminate phytosaurs, the aetosaurs Desmatosuchus sp. and cf Stagonolepis sp., a probable theropod, and other, indeterminate archosaurs. Five of these...

Dinoflagellate cysts from the Upper Triassic (Rhaetian) strata of the Tabas Block, East - Central Iran

Rhaetian strata from the Nayband Formation of the Tabas block, East- Central Iran, were studied palynologically. The materialexamined contained moderately diverse and well-preserved dinoflagellate cyst assemblages which lead to the identification ofRhaetogonyaulax rhaetica Zone. The assigned age of this dinozone (Rhaetian) is justified by plant fossils such as Equisetitesarenaceus, Scytophyllum...

The Permian–Triassic boundary crisis and Early Triassic biotic recovery

This issue of Palaeogeography Palaeoclimatology Palaeoecology is devoted to papers on the Permian– Triassic boundary crisis and Early Triassic biotic recovery. It is an outgrowth of the Symposium on Early Triassic Chronostratigraphy and Biotic Recovery that was held in Chaohu, China, on May 21st–23rd, 2005 under the auspices of IGCP Project 467 and attended by about 200 Earth scientists with a ...
