Palaeo After Dark

The gang kicks off a summer of archosaurs by talking about crocodyliforms. The first paper describes an early Cenozoic large notosuchian, and the second paper investigates how cryptic species impacts divergence times within the clade. Meanwhile, Curt diagnoses a problem, James tries to “help”, and Amanda does not care.

The gang tries to discuss two papers that look at the evolutionary impacts of the K-Pg mass extinction. Specifically, they look at one paper that estimates sampling probability throughout the late Cretaceous to determine if record bias influences our understanding of the extinction, and another paper that looks at spec

The gang discusses two papers that look at the evolutionary impact of shifts in habitat occupation. The first paper looks at a clade of sharks moving into the depths, and the second paper investigates habitat shifts in mammals across the Cretaceous and Paleogene. Meanwhile, Amanda has some opinions, James is doing much

The gang discusses two papers that use morphometrics to investigate patterns of selection on bird morphology. The first paper looks at the morphology of feathers, while the second paper looks more broadly at various parts of the avian body. Meanwhile, James breathes new life into a classic, Amanda is passionate about f

The gang discusses two papers that look at preserved skin/external tissues. The first paper shows a unique record of Cambrian molting, and the second paper looks at the first preserved samples of plesiosaur skin. Meanwhile, Amanda commits an "own goal”, Curt shares some old internet fun, and James has opinions about fi

The gang discusses two papers that look into the evolution and timing of key morphological innovations within animal groups. The first paper describes possible raptorial appendages in fossil artiopods, and the second paper finds early evidence of modern bird morphologies in the Jurassic. Meanwhile, Amanda gloats, Curt
