Phylogeny, taxonomy, and biogeography of Pterocarya (Juglandaceae)

Song, Yi-Gang ; Li, Ying ; Meng, Hong-Hu ; Fragnière, Yann ; Ge, Bin-Jie ; Sakio, Hitoshi ; Yousefzadeh, Hamed ; Bétrisey, Sébastien ; Kozlowski, Gregor

In: Plants, 2020, vol. 9, no. 11, p. 1524

Relict species play an important role in understanding the biogeography of intercontinental disjunctions. Pterocarya (a relict genus) is the valuable model taxon for studying the biogeography of East Asian versus southern European/West Asian disjunct patterns. This disjunction has not been as well studied as others (e.g., between Eastern Asia and North America). Several phylogenetic studies...

The Eomyidae in Asia: Biogeography, diversity and dispersals

Kimura, Yuri ; Casanovas-Vilar, Isaac ; Maridet, Olivier ; Kalthoff, Daniela C. ; Mörs, Thomas ; Tomida, Yukimitsu

In: Fossil Imprint, 2020, vol. 76, no. 1, p. 181-200

In Asia, the first find of an eomyid rodent was reported almost one century after the first studies of the family Eomyidae in North America and Europe. Since then, eomyid rodents have been increasingly found in Asia particularly over the past two decades. Here, we review the Asian record of this family at the genus level. Currently, 22 species within 14 genera were reported from Asia,...

Cranial osteology of the early cretaceous turtle Pleurosternon bullockii (paracryptodira: pleurosternidae)

Evers, Serjoscha W. ; Rollot, Yann ; Joyce, Walter G.

In: PeerJ, 2020, vol. 8, p. e9454

Pleurosternon bullockii is a turtle from the Early Cretaceous of Europe known from numerous postcranial remains. Only one skull has so far been referred to the species. Pleurosternon bullockii belongs to a group of turtles called pleurosternids, which is thought to include several poorly known taxa from the Late Jurassic and Early Cretaceous of Europe and North America. Pleurosternids and...

A new species of baenid turtle from the Early Cretaceous Lakota Formation of South Dakota

Joyce, Walter G. ; Rollot, Yann ; Cifelli, Richard L.

In: Fossil Record, 2020, vol. 23, no. 1, p. 1–13

Baenidae is a clade of paracryptodiran turtles known from the late Early Cretaceous to Eocene of North America. The proposed sister-group relationship of Baenidae to Pleurosternidae, a group of turtles known from sediments dated as early as the Late Jurassic, suggests a ghost lineage that crosses the early Early Cretaceous. We here document a new species of paracryptodiran turtle, Lakotemys...

Notes on the cheek region of the Late Jurassic theropod dinosaur Allosaurus

Evers, Serjoscha W. ; Foth, Christian ; Rauhut, Oliver W.M.

In: PeerJ, 2020, vol. 8, p. e8493

Allosaurus, from the Late Jurassic of North America and Europe, is a model taxon for Jurassic basal tetanuran theropod dinosaurs. It has achieved an almost iconic status due to its early discovery in the late, 19th century, and due to the abundance of material from the Morrison Formation of the western U.S.A., making Allosaurus one of the best-known theropod taxa. Despite this, various...

Late Jurassic theropod dinosaur bones from the Langenberg Quarry (Lower Saxony, Germany) provide evidence for several theropod lineages in the central European archipelago

Evers, Serjoscha W. ; Wings, Oliver

In: PeerJ, 2020, vol. 8, p. e8437

Marine limestones and marls in the Langenberg Quarry provide unique insights into a Late Jurassic island ecosystem in central Europe. The beds yield a varied assemblage of terrestrial vertebrates including extremely rare bones of theropod from theropod dinosaurs, which we describe here for the first time. All of the theropod bones belong to relatively small individuals but represent a wide...

The last Palaeoproteus (Urodela: Batrachosauroididae) of Europe

Vasilyan, Davit ; Yanenko, Vadym

In: Scientific Reports, 2020, vol. 10, p. 2733

The Batrachosauroididae are an enigmatic group of salamanders known from the Cretaceous and Tertiary of North America and Europe. In Europe, the family is known only by two species of the genus Palaeoproteus. The genus has limited distribution in Western and Central Europe. In the present paper, we describe a new species, Palaeoproteus miocenicus, from the early late Miocene (11–9 Ma) of...
