Rapid evolution and cranial morphospace expansion during the terrestrial to marine transition in elapid snakes Open
Ecological transitions can trigger rapid phenotypic evolution and novelty, yet the tempo and mode of such changes remain poorly understood in clades that diversify across broad geographic scales, such as continents and oceans. We analysed …

Multiple Paths to a Larger Mouth: Morphological Divergence in Two Island Populations of Australian Tiger Snakes (Notechis scutatus) Open
We studied ontogenetic variation in skull morphology in tiger snakes sampled from mainland South Australia (Coffin Bay), mainland Western Australia (Herdsman Lake), Franklin Island, and Hopkins Island. The snakes from the two islands were …

Trait-space disparity in fish communities spanning 380 million years from the Late Devonian to present Open
The diversity and distribution of species’ traits in an ecological community determine how it functions. While modern fish communities conse rve trait space across similar habitats, little is known about trait-space variation through deep …

A new booid snake from the Eocene (Lutetian) Konservat-Lagerstätte of Geiseltal, Germany, and a new phylogenetic analysis of Booidea Open
We describe two exceptionally preserved fossil snakes from the Eocene Konservat-Lagerstätte of Geiseltal, located in the state of Saxony-Anhalt, Germany. The two snake specimens, GMH LIX-3-1992 and GMH XXXVIII-20-1964, can be confidently i…

Pleistocene raptors from cave deposits of South Australia, with a description of a new species of <i>Dynatoaetus</i> (Accipitridae: Aves): morphology, systematics and palaeoecological implications Open
The Pleistocene fossil record of Australian raptors (Accipitridae: eagles, hawks and Old World vultures) is very poorly understood with only three distinct extinct species confirmed until now. The small Necrastur alacer remains unstudied; …

Shape and Size Variation in Elapid Snake Fangs and the Effects of Phylogeny and Diet Open
Recent studies have found correlations between the shape of snake teeth/fangs and diet. These studies were done at a very broad phylogenetic scale, making it desirable to test if correlations are still detectable at a narrower evolutionary…

The affinities of the Late Triassic <i>Cryptovaranoides</i> and the age of crown squamates Open
Most living reptile diversity is concentrated in Squamata (lizards, including snakes), which have poorly known origins in space and time. Recently, † Cryptovaranoides microlanius from the Late Triassic of the United Kingdom was described a…

Predicting predator–prey interactions in terrestrial endotherms using random forest Open
Species interactions play a fundamental role in ecosystems. However, few ecological communities have complete data describing such interactions, which is an obstacle to understanding how ecosystems function and respond to perturbations. Be…

A giant armoured skink from Australia expands lizard morphospace and the scope of the Pleistocene extinctions Open
There are more species of lizards and snakes (squamates) alive today than any other order of land vertebrates, yet their fossil record has been poorly documented compared with other groups. Here, we describe a gigantic Pleistocene skink fr…

Multiple modes of inference reveal less phylogenetic signal in marsupial basicranial shape compared with the rest of the cranium Open
Incorporating morphological data into modern phylogenies allows integration of fossil evidence, facilitating divergence dating and macroevolutionary inferences. Improvements in the phylogenetic utility of morphological data have been sough…

Disparate continental scale patterns in floral host breadth of Australian colletid bees (Colletidae: Hymenoptera) Open
Plant-bee networks are rarely, if ever, studied quantitatively at continental scales, yet these have the potential to inform how biota and ecosystems are assembled beyond narrower regional biomes. The short-tongued bee family Colletidae co…
