Reefal regions were biodiversity hotspots throughout the Phanerozoic Open
Reefs are important hotspots of marine biodiversity today and have acted as cradles of diversification in the geological past. However, we know little about how the diversity of reef-supporting regions varied through deep time, and how thi…

Neuroanatomical convergence between pterosaurs and non-avian paravians in the evolution of flight Open
The oldest known pterosaurs lived approximately 220 million years ago1 and were already animals capable of powered flight,2 an ability that later evolved independently among paravian dinosaurs, the group that includes…

A basal elasmosaurid plesiosaur from the upper Albian– lower Cenomanian? Cambridge Greensand Open
An historical indeterminate elasmosaurid specimen CAMSM X50356 (CAMSM = Sedgwick Museum) collected during the 19th century is described. The specimen comes from the Cenomanian Cambridge Greensand although the possibility of an Albian–lower…

Mosaic anatomy in an early fossil squamate Open
Squamates (lizards and snakes) comprise almost 12,000 living species, with wide ecological diversity and a crown group that originated around 190 million years ago 1,2 . Conflict between morphology and molecular phylogenies indicates a com…

A wide range of abiotic and biotic variables leaves most variation in bird nest architecture unexplained Open
Nests are the locations or containers for offspring, and mediate interactions between offspring and the environment. However, understanding how environmental factors shape the evolution of nest architecture is complicated. In particular, t…

Evolutionary assembly of crown reptile anatomy clarified by late Paleozoic relatives of Neodiapsida Open
Living reptiles include more than 20,000 species with disparate ecologies. Direct anatomical evidence from Neodiapsida, which includes the reptile crown-group and its closest extinct relatives, shows that this diversity originates from a s…

Body mass evolution as a driver of morphological and ecological diversity in terrestrial mammals Open
Body mass plays a fundamental role in the macroevolutionary dynamics of morphological, ecological, and phylogenetic diversification. Given biomechanical principles, large body masses in terrestrial vertebrates may impose important constrai…

Somitic Change Drives Changes in Vertebral Regionalisation in African Cichlids Despite Strong Canalisation of Somite Number Open
Vertebrae arise from somites, transient embryonic segments that rhythmically bud from the presomitic mesoderm during axial elongation. The number and identity of vertebrae are ultimately determined by somitogenesis and subsequent anterior-…

African Cichlid Lake Radiations Recapitulate Riverine Axial Morphologies Through Repeated Exploration of Morphospace Open
African cichlids comprise more than 1800 species of freshwater fishes, with remarkable adaptive radiations in Lakes Tanganyika, Malawi, and Victoria that have given rise to extraordinary morphological diversity. However, the evolution of t…

Diversification dynamics of vegetation during the Cenozoic in the Neotropics: a palynological perspective from Colombia Open
The Neotropics host the highest diversity of plants on the Earth today and have done since at least the late Paleogene (~58 Ma). Several mechanisms have been proposed to explain this elevated diversity, but the empirical patterns of Neotro…

The first and most complete dinosaur skeleton from the Middle Jurassic of Scotland Open
The fossil record of dinosaurs in Scotland mostly comprises isolated highly fragmentary bones from the Great Estuarine Group in the Inner Hebrides (Bajocian–Bathonian). Here we report the first definite dinosaur body fossil ever found in S…

Towards a comprehensive anatomical matrix for crown birds: phylogenetic insights from the pectoral girdle and forelimb skeleton Open
Phylogenetic analyses of phenotypic characters in crown-group birds often recover results that are strongly incongruous with the findings of recent phylogenomic analyses. Furthermore, existing morphological datasets for crown birds are fre…

Cranial osteology and neuroanatomy of the late Permian reptile <i>Milleropsis pricei</i> and implications for early reptile evolution Open
Millerettidae are a group of superficially lizard-like Permian stem reptiles originally hypothesized as relevant to the ancestry of the reptile crown group, and particularly to lepidosaurs and archosaurs. Since the advent of cladistics, mi…

Of flippers and wings: The locomotor environment as a driver of the evolution of forelimb morphological diversity in mammals Open
The early diversification of tetrapods into terrestrial environments involved adaptations of their locomotor apparatus that allowed for weight support and propulsion on heterogeneous surfaces. Many lineages subsequently returned to the wat…

Macroevolutionary drivers of morphological disparity in the avian quadrate Open
In birds, the quadrate connects the mandible and skull, and plays an important role in cranial kinesis. Avian quadrate morphology may therefore be assumed to have been influenced by selective pressures related to feeding ecology, yet large…

Spatial standardization of taxon occurrence data—a call to action Open
The fossil record is spatiotemporally heterogeneous: taxon occurrence data have patchy spatial distributions, and this patchiness varies through time. Large-scale quantitative paleobiology studies that fail to account for heterogeneous sam…
