It has long been debated why groups such as non-avian dinosaurs became extinct whereas
mammals and other lineages survived the Cretaceous/Paleogene mass extinction 66 million …

Understanding how biodiversity has changed through time is a central goal of evolutionary
biology. However, estimates of past biodiversity are challenged by the inherent …

Discerning paleoclimate parameters in depositional systems of the continental interior is
challenging because the system response and stratigraphic record of climate are controlled …

The orbit is one of several skull openings in the archosauromorph skull. Intuitively, it could
be assumed that orbit shape would closely approximate the shape and size of the eyeball …

Paleoenvironmental factors such as climate change are often hypothesized as critical for
ecosystem changes over evolutionary time scales. Theoretically, these changes should be …

The disjunct geographical range of many lineages of caudates points to a complex
evolutionary and biogeographic history that cannot be disentangled by only considering the …

An important parameter in studying the macroevolutionary history of a clade is the variation
of its body size. However, the analysis of this parameter in archosauromorphs has been …

Stereospondyls underwent a global radiation in the Early Triassic, including an abundance
of small-bodied taxa, which are otherwise rare throughout the Mesozoic. Lapillopsidae is …

Earth's land plants have been shaped by tectonic, climatic and atmospheric evolution for at
least 400 million years. The rift basins of Argentina record a continuous record of Triassic …

Dinosaur footprints from the Upper Triassic Xujiahe Formation (T 3 x 3) in the Sichuan Basin
are the earliest records of dinosaurs from China. Hitherto, little has been known about …
