Journal of Anatomy, EarlyView.A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

The Permo-Carbonigferous Facies Development in Thailand: A plate tectonic discussion [PDF]
, 1989 The Permo-Carboniferous sedimentary facies development in Thailand reflects the late Variscan orogeny in S E Asia. During the Carboniferous and Permian, a N -S trending trough separated the " S h a n Thai Craton" and the "Indosinia Craton".

Nodular calcrete from the Lower Permian Korpád Sandstone Formation (borehole Dinnyeberki 9015, Mecsek Mts, Hungary) and its palaeoenvironmental significance [PDF]
, 2013 The Korpád Sandstone in the 9015 drill core (Mecsek Mts.) consists of red mudstones and interbedded calcrete crusts with sandstones and conglomerates. Calcrete microfabrics reveal micritic mottles, rhizocretions, smaller root casts and Microcodium-like ...

Palaeoecological and possible evolutionary effects of early Namurian (Serpukhovian, Carboniferous) glacioeustatic cyclicity [PDF]
, 2008 Early Namurian (Serpukhovian, Carboniferous), sedimentary cycles in the Throckley and Rowlands Gill boreholes, near Newcastle upon Tyne, UK, consist of fossiliferous limestones overlain by (usually unfossiliferous) black mudstone, followed by sandstones ...

Permian ancestors of Hymenoptera and Raphidioptera [PDF]
ZooKeys, 2013 The origin of Hymenoptera remains controversial. Currently accepted hypotheses consider Hymenoptera as the first side branch of Holometabola or sister-group to Mecopteroidea. In contrast, fossils confirm the idea of Martynov that Hymenoptera are related to Megaloptera and Raphidioptera.

The Chamrousse Ophiolite (Western Alps, France): Relict of a Devono‐Carboniferous Ocean
Terra Nova, EarlyView.ABSTRACT The Chamrousse ophiolite (Western Alps, France) is one of the best‐preserved Variscan relicts of Cambro‐Ordovician oceanisation within the northern Gondwana margin. This study presents new in situ U–Pb isotope analyses on zircon grains from that ophiolite, revealing that the oceanic stage in Chamrousse has occurred 150 Ma later than estimated.

Terra Nova, EarlyView.ABSTRACT Mylonites and pseudotachylytes play a crucial role in defining the rheology of extending continental crust. In this context, determining the age of brittle‐ductile deformation is fundamental to understanding the rifting evolution stages. Here, we investigate the Premosello Shear Zone, an extensional structure of the Ivrea‐Verbano lower crust ...
