Comment on “Bilaterian Burrows and Grazing Behavior at >585 Million Years Ago” [PDF]
Pecoits et al. (Reports, 29 June 2012, p. 1693) describe bilaterian trace fossils and assign them an Ediacaran age based on the age of a granite interpreted as intrusive.

Late Carboniferous – Early Permian (Ghzelian – Artinskian) Palynomorphs
Abstract. The preliminary results of the palynological investigations in the Late Carboniferous – Early Permian of Northeast Libya indicate that at least two successive intervals can be readily recognised:Ghzelian – Asselian interval. This lower interval is characterised by assemblages showing a dominance of saccate pollen; miospores usually occur in ...

Microbial Endolithic Community at Meteor Crater
Abstract Postimpact recovery and evolution in response to climate changes produced a modern ecosystem at Meteor Crater dominated by a grassland and woodland of piñon and juniper, which has been used to evaluate floral and megafaunal consequences of impact cratering during the Phanerozoic Eon of complex life.

ABSTRACT Thin ferruginous sandy crusts are common on top of sandstone beds in the Early Permian post‐glacial deposits of the Paraná Basin in southern Brazil. These crusts usually preserve wrinkle structures, suggesting that they might be a product of microbial mediation.

GINKGOPHYTES FROM THE UPPER PERMIAN OF THE BLETTERBACH GORGE (NORTHERN ITALY)
Fossil evidence of late Palaeozoic ginkgophytes is rare; Palaeozoic floras in which ginkgophytes are abundant or represent a predominant element have not previously been described.

Reassessment of mid-Carboniferous glacial extent in southwestern Gondwana (Rio Blanco Basin, Argentina) inferred from paleo-mass transport of diamictites [PDF]
Late Paleozoic glacial diamictites occur in many localities in western Argentina, indicating that the region was strongly affected by glaciation during the mid-Carboniferous (late Serpukhovian–early Bashkirian).

Late Permian magnetostratigraphy and its global correlation
A calibration among magnetic polarity sequence, biostratigraphy zonation and isotopic age reveals that the boundary between the Carboniferous-Permian reversed Polarity Superzone and Permian-Triassic Mixed Polarity Superzone occurs at the top of the Wordian Stage of the Guadalupian Series and is dated as 265 Ma.
