Osteology and phylogeny of Robustichthys luopingensis, the largest holostean fish in the Middle Triassic
Joseph Gillespie –– Important contribution to fish phylogenetics and evolution
Using GIS to examine biogeographic and macroevolutionary patterns in some late Paleozoic cephalopods from the North American Midcontinent Sea
Graciela Piñeiro –– This is an interesting paper that intends to document how much the changing climatic conditions (such as those related to the Late Carboniferous glaciations) have affected the geographic distribution and the extinction/speciation patterns of some cephalopods throughout the Pennsylvanian and Early Permian North American Midcontinent Sea by using Geographic Information Systems (GIS). The study shows ambiguous results probably influenced for the small sample size, particularly when applying statistical testing, demonstrating the relevance of the sample size in the achievement of reliable conclusions.
A prevalence of Arthropterygius (Ichthyosauria: Ophthalmosauridae) in the Late Jurassic—earliest Cretaceous of the Boreal Realm
Mark Young –– This paper provides a thorough description and review of Russian ophthalmosaurid ichthyosaurs. The hypotheses, descriptions and identifications within give a different interpretation of Upper Jurassc ichthyosaur evolution.
The coast of giants: an anthropometric survey of high schoolers on the Adriatic coast of Croatia
Andrew Gray –– This is a fascinating study which carefully examines the extreme mean heights, and wide variation in heights, among young men and women on the Adriatic coast of Croatia, and explores the possible reasons behind this.
A small caseid synapsid, Arisierpeton simplex gen. et sp. nov., from the early Permian of Oklahoma, with a discussion of synapsid diversity at the classic Richards Spur locality
Graciela Piñeiro –– The paper describes a new caseid pelycosaur from the Early Permian of Oklahoma. Caseids are one of the basalmost known synapsids having evolved herbivory and every new discovering will account for a better understanding of the evolutionary history of this group.
A new testudinoid turtle from the middle to late Eocene of Vietnam
Hans-Dieter Sues –– New species from a previously poorly sampled area; fossil sample of considerable size (probably representing a single population) showing variation in morphological features.
The Early Pliocene extinction of the mega-toothed shark Otodus megalodon: a view from the eastern North Pacific
Kenneth De Baets –– As the data have relevance to constrain the age of extinction of this now extinct giant shark - it would be relevant to ecologists, evolutionary biologist to further constrain the causes of its demise.
Integrating gross morphology and bone histology to assess skeletal maturity in early dinosauromorphs: new insights from Dromomeron (Archosauria: Dinosauromorpha)
John Hutchinson –– Along with other work ongoing by these and other authors on early archosaurian ontogenetic variation and histology, this study is shedding important light on how growth patterns evolved and how variable certain characters used in systematic analyses are. This is important insight.
Efficient generation of human primordial germ cell-like cells from pluripotent stem cells in a methylcellulose-based 3D system at large scale
Shao-Chen Sun –– A system which produces more primordial germ cell-like cells.
Shell variability in the stem turtles Proterochersis spp.
Jérémy Anquetin –– Detailed description of morphological variability in early turtles

A new chapter in our jellyfish benthic stages search published in @PeerJ! This paper by @ju_vbtv, @VanderveerHenkW and me documents first in situ find of polyps and podocysts of 2 common North Sea jellyfish species. Found hiding inside bivalve shells. 1/11

Кто проживает в горах океана? Astrolirus patricki – семирукие морские звезды, обнаруженные на подводных горах Тихого океана в компании губок, на которые иногда даже по трое забираются. Новый вид назван, конечно же, в честь Патрика, дружочка Спанч Боба.
