Editor rating: 9 / 10Kenneth De Baets –– The manuscript introduces a new metric for drift potential of cephalopod shells relevant for paleontologist and biologists. When applying it on fossil ammonoids and modern nautilids, the author demonstrates that long post-mortem drift is more than sometimes claimed and that their geographic ranges are reasonable proxies for geographic range during life making it also of great interest to biogeographers and ecologists. The results also suggest the presence modern or recently extirpated populations of Nautilus in the Indian ocean, which is of relevance for conservation efforts.
Editor rating: 8 / 10Mathew Wedel –– This work is legitimately groundbreaking in its scope and in its potential to move the field forward. The papers in this series seem destined to become citation classics.

Editor rating: 8 / 10J. Thewissen –– Modern toothed whales (odontocetes) are interesting because they are able to shed the design constraints that most mammals, including Eocene whales, have (for instance, in the number of teeth and the number of phalanges). Early odontocetes, such as the one described here, are on that path: they are exploring the limits of the mammalian bauplan. We don't know much about the morphology of these groups, so every fossil described helps us understand that evolutionary exploration better.
Editor rating: 8 / 10Andrew Farke –– Detailed description of an important taxon for sauropod workers.
Editor rating: 8 / 10Philip Cox –– This is a thorough study on an extensive dataset that will provide a model for other such macroevolutionary investigations.
Editor rating: 8 / 10Andrew Farke –– This study presents data applicable for many paleontologists in trying to establish life history information for snakes extant and extinct.
Section Editor rating: 8 / 10Andrew Farke –– Excellent imagery and descriptions of an important taxon.
Editor rating: 9 / 10Luis Eguiarte –– Gunnera is a genus of plants that have fascinated scientist for a long time, in particular for the very large leaves of some species and because its symbiotic relationship with the nitrogen fixing cyanobacteria Nostoc. For a many years, some botanists suspected it to be a very old, primitive genus, perhaps basal in the phylogeny of the Angiosperms. While latter molecular phylogenies did not support this position, this paper shows that indeed Gunnera is an old genus, with a complex evolutionary and phylogeographic history, and a recent radiation in the Andes. All these new results are relevant for understanding why the Neotropics have so many plant species, more than any other similar region in the planet.
Editor rating: 8 / 10Curtis Daehler –– This work provides genetic evidence suggesting the native range of a widely distributed animal that was accidentally spread by humans starting hundreds of years ago.
