What affects power to estimate speciation rate shifts?

Editor rating: 6 / 10

William Amos –– there is increasing interest in measuring 'evolution', so the ability to use phylogenies to estimate speciation rates is of considerable utility. However, the methods are non-trivial and this paper does a good job of assessing which methods work best and under what circumstances.
Triassic pentadactyl tracks from the Los Menucos Group (Río Negro province, Patagonia Argentina): possible constraints on the autopodial posture of Gondwanan trackmakers

Editor rating: 7 / 10

Kenneth De Baets –– The authors describe new finds of a widespread trace fossil and manage to use it to constrain the anatomy of its producer. It will therefore be relevant for ichnologist, (paleo)biologists and (paleo)ecologists.

Editor rating: 7 / 10

Graciela Piñeiro –– This is an important contribution to the dinosaur reproductive behavior, and offers a pormenorized study of the evidence to suggest the presence of a cuticle-like layer in oviraptorid and alvarezsaurid dinosaur eggs.

Editor rating: 6 / 10

Erik Seiffert –– This paper presents novel osteohistological data from fossil species that are critically important for our understanding of the evolution of mammalian physiology and anatomy.
A Miocene pygmy right whale fossil from Australia

Editor rating: 6 / 10

Mark Young –– While this is a fragmentary fossil specimen, it is important as the fossil record of pygmy right whales is poorly known (and thus their evolutionary history is poorly known).

Hans-Dieter Sues –– Important study on troodontid cranial structure.
Gorgonopsian therapsids (Nochnitsa gen. nov. and Viatkogorgon) from the Permian Kotelnich locality of Russia

Editor rating: 7 / 10

Mark Young –– Gorgonopsians are an unstudied clade, which this paper helps to begin to rectify.
