A stem acrodontan lizard in the Cretaceous of Brazil revises early lizard evolution in Gondwana. 2015. Nature Communications
University of Alberta paleontologists have discovered a new species of lizard, named Gueragama sulamericana, in the municipality of Cruzeiro do Oeste in Southern Brazil in the rock outcrops of a Late Cretaceous desert, dated approximately 80 million years ago.

When you think about fossils, lizards might be not be one of the first groups that springs to mind. However, they do have a pretty neat fossil record, stretching back over 150 million years. One group of lizards, iguanians, are still around today and comprises about 1700 different species! One sub-group of these iguanians, acrodonts, are thought to have originated in east Gondwana – part of the ‘old world’ including Africa. Acrodonts are named after weird features in their [...]
A Mesozoic bird from Gondwana preserving feathers. 2015. Nature Communications.
Abstract: The fossil record of birds in the Mesozoic of Gondwana is mostly based on isolated and often poorly preserved specimens, none of which has preserved details on feather anatomy.
We provide the description of a fossil bird represented by a skeleton with feathers from the Early Cretaceous of Gondwana
The oldest record of ornithuromorpha from the early cretaceous of China. 2015. Wang, M., et. al. Nature Communications
Abstract: Ornithuromorpha is the most inclusive clade containing extant birds but not the Mesozoic Enantiornithes. The early evolutionary history of this avian clade has been advanced with recent discoveries from Cretaceous deposits, indicating that Ornithuromorpha

In the NewsEarly snakes have been in the news, with a press push and gorgeous Julius Csotonyi artwork accompanying the publication of a paper in Nature Communications. The new paper by Michale Caldwell et al have described four ancient snake species dating to the mid-Jurassic, including Diablophis gilmorei. Read more at Laelaps. This is another fine example of why art is central to palaeontological outreach. That iconic ambassador of American sauropods, Dippy the Diplodocus, is ceding the main [...]
Macmillan have released an interesting press release, announcing that all research papers published in their 49 Nature Publishing Group (NPG) journals, including Nature, will be made free to read online, via one of Digital Science’s pet projects, ReadCube (note that Digital Science is also owned by Macmillan). These articles can be annotated in ReadCube, but not copied, printed, or downloaded. This is not open access*, and NPG have been very careful and explicit about stating this. What is [...]

Floating pumice. Jeff Butterworth A team of scientists from the UK, the US, Australia and New Zealand have modelled the fate of a huge floating raft of volcanic rocks that formed in 2012 during a submarine eruption of a Pacific volcano. Described in this month’s edition of Nature Communications, they show how satellite images of

Sergio Almécija, investigador asociado del Institut Català de Paleontologia Miquel Crusafont (ICP), lidera una publicación en Nature Communications donde analiza el fémur de Orrorin tugenensis, un miembro muy primitivo del linaje humano que vivió hace 6 millones de años en Kenia. El estudio revela que el fémur de Orrorin presenta una combinación única de caracteres primitivos y modernos, siendo intermedio temporalmente y morfológicamente entre los antropomorfos fósiles del Mioceno [...]
This recent study, published online on Sept. 27 in the Nature Communications, breaks new ground in the standard measurements of the Casimir effect known to scientists. The experiment used nanostructured (micro-ridged) metallic plates to suppress the force to a much lower rate than ever recorded previously, said Ricardo Decca, Ph.D., professor of physics at IUPUI.

Sea monsters lying in wait for unsuspecting prey sounds scary enough. But slap on a tail that let them run down their dinner—much like today's great white sharks—and mosasaurs could truly be considered one of the ancient world's nightmares.
And that's exactly what a new study published September 10 in Nature Communications has confirmed.
A 72-million-year-old fossil specimen
Investigadores de la Universidad de Bolonia han descubierto una nueva especie de dinosaurio saurópodo, de la familia Rebbachisauridae. al que han nombrado Tataouinea hannibalis, que posee un sistema respiratorio muy similar a la de las aves actuales.
En el estudio, publicado en la revista "Nature Communications", se presenta al animal prehistórico como "la primera y mejor conservada" muestra
Hace 9 millones de años en América del Sur vivían hasta 14 especies de cocodrilos, 7 de las cuales compartían la misma zona geográfica, un fenómeno nunca observado en especies actuales. Paleontólogos de la Universidad de Zurich con la participación del investigador del ICP Massimo Delfino, publican el hallazgo este martes en la revista Nature Communications. El estudio también describe la extinción de todas estas especies hace 5 millones de años, probablemente como consecuencia [...]

Sauropod dinosaur osteoderms from the Late Cretaceous of Madagascar. 2011. K. Curry Rogers, et al. Nature Communications 2, article number:564.Abstract: Osteoderms are bones embedded within the dermis, and are common to select members of most major tetrapod lineages. The largest known animals that bear osteoderms are members of Titanosauria, a diverse clade of sauropod dinosaurs.Here we report
