"Dinosaurs were thriving at the beginning of the Cretaceous, and yet major changes had occurred across the Jurassic-Cretaceous boundary. The sauropods were replaced by ornithopods as dominant herbivores, which has been explained by many ecological scenarios, including the replacement of gymnosperms...
"Modern-type marine ecosystems became established in the Triassic following the devastation of the Permian-Triassic mass extinction. Attention has been focused on higher levels of these food chains, but the primary levels have not been established in detail. Here, we present evidence of microcoprol...
"Mammals (or properly, mammaliaforms) originated in the Late Triassic and the first 50 Myr of their evolution through Late Triassic and Early Jurassic are best documented by rich faunas from numerous localities around Bristol in south-west England and in South Wales. The mode of preservation of the...
"Corallite sizes reflect a continuum in the efficacy of photosymbiosis in colonial reef corals, with smaller corallite sizes generally associated with higher autotrophy. Using a large compilation of reef-coral traits and corallite diameters as a proxy, we test here the hypothesis that photosymbioti...
"Understanding spatial variation in origination and extinction can help to unravel the mechanisms underlying macroevolutionary patterns. Although methods have been developed for estimating global origination and extinction rates from the fossil record, no framework exists for applying these methods...
"Although patchy, the fossil record of coleoids bears a wealth of information on their soft part anatomy. Here, we describe remains of the axial nerve cord from both decabrachian (Acanthoteuthis, Belemnotheutis, Chondroteuthis) and octobrachian (Plesioteuthis, Proteroctopus, Vampyronassa) coleoids ...
"The bioregionalization of the Devonian fauna in southwest Gondwana has been extensively studied, focusing on the occurrences of brachiopods and trilobites, however, little attention has been given to Conulariids. The main goal of this paper is to propose a bioregionalization for the Conulariids (C...
"The Arctic is warming four times faster than the global average, and plant communities are responding through shifts in species abundance, composition and distribution. However, the direction and magnitude of local plant diversity changes have not been explored thus far at a pan-Arctic scale. Usin...
"Siliceous marine ecosystems play a critical role on the Earth’s climate system through its influence on organic carbon burial and rates of marine authigenic clay formation (i.e. reverse weathering). The ecological demise of silicifying organisms associated with the Permian-Triassic mass extinction...
"The end of the Late Paleozoic Ice Age is associated with a distinct vegetation turnover that gradually replaced wetland forests with a vegetation dominated by drought tolerant plants. The Kungurian plant fossil and sporomorph assemblages of the Southern Alps are among the most rich, diverse and we...
