title: The first articulated skull roof and braincase of <i>Melvius chauliodous</i> (Amiidae, Vidalamiinae) from the Upper Cretaceous Kirtland Formation, San Juan Basin, New Mexico

description: A new, exceptionally well-preserved articulated skull roof and braincase of <i>Melvius chauliodous</i>, from the Kirtland Formation of New Mexico, reveals new features that provide detailed osteological information for <i>Melvius</i>, thus allowing for a reassessment of characters that defines the genus, its two recognized species <i>M</i>. <i>chauliodous</i> and <i>M</i>. <i>thomasi</i>, and its phylogenetic relationships within Vidalamiinae. The new features include the presence of dermopterotic rays (‘ribs’) and parietal ray bundles, previously unknown for both species of <i>Melvius</i>. The presence of elongated dermopterotic rays, a feature previously considered to be distinctive for the genus <i>Calamopleurus</i>, and tribe Calamopleurini, is now documented in <i>Melvius</i>, but these rays differ in their point of origination at the posteromedial corners of both dermopterotics. Bundles of short fan-shaped rays emanating from below the posterolateral corners of the parietals are also documented in both species of <i>Melvius</i>. <i>Melvius</i> was previously placed in the tribe Vidalamiini (Subfamily Vidalamiinae), but because it shares some unique features with members of the tribe Calamopleurini and the genus <i>Calamopleurus</i>, its placement within Vidalamiini, and the recognition of these two distinct clades (tribes) within Vidalamiinae, are not supported in our phylogenetic analysis. Previous characters distinguishing <i>Melvius</i> species, particularly differences in postinfraorbital ornamentation between <i>M</i>. <i>chauliodous</i> and <i>M</i>. <i>thomasi</i>, are considered dubious. However, other features may serve to determine interspecific variation or differences. For the present, we retain both species until more definitive material of <i>M. thomasi</i> is described.

title: A new hupehsuchian (Reptilia: Ichthyosauromorpha) from the Lower Triassic of South China with implications for the evolution of polydactyly

description: Hupehsuchia, an enigmatic group of marine reptiles from the Lower Triassic of South China, is characterized by a suite of features including polydactyly in either or both fore and hind limbs. Particularly, one parahupehsuchine specimen shows seven-digited forelimbs and a six-digited hind limb. However, questions remain as to what sequence manus configuration evolved in hupehsuchians. Here, we describe a new hupehsuchian with seven manual digits associated with extra carpals and digits. Our new phylogeny revealed the evolutionary sequence of extra carpals, metacarpals, and phalanges in hupehsuchians through preaxial and central polydactyly and suggested that the polydactyly of the manus evolved stepwise in hupehsuchians.

title: A new eutherian mammal from the Upper Cretaceous Bayinshire Formation of Mongolia

description: <i>Bayshinoryctes shuvalovi</i> gen. et sp. nov. is based on a fragmentary skull including right maxilla associated with right and left dentaries with partially preserved dentition from the Upper Cretaceous (Turonian–Santonian) Bayinshire Formation at Bayshin Tsav locality in Gobi Desert, Mongolia. Undated Bayesian analyses of two different data matrices recover the new taxon as a stem placental mammal within the clade containing also <i>Maelestes</i> from the Upper Cretaceous (Campanian) of Mongolia and <i>Batodon</i> from the Upper Cretaceous (Maastrichtian) of North America. <i>Bayshinoryctes</i> gen. nov. differs from <i>Maelestes</i> by a few dental characters, including three-rooted P4, double-rooted p3, and p5 with metaconid swelling.
