Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

The Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

Journal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

Biostratigraphy of the Danian/Selandian transition: A case study from Kamestan anticline section, northwest of Izeh city in Khuzestan province, Southern Iran [PDF]

, 2010
The planktonic foraminifera turnover across the Danian-Selandian boundary (early to late Paleocene, ~60 Ma) has been studied in the Kamestan anticline section. The studied interval span planktonic foraminifera zones P2-P3.

Breaking the ice: multiple origins of ice‐binding/antifreeze proteins

The FEBS Journal, EarlyView.
Ice‐binding proteins (IBPs) evolved independently in many organisms during Cenozoic cooling and glaciation. In flounders, α‐helical IBPs evolved from an antiviral protein, while similar IBPs arose independently from different progenitors in three other fish lineages.
