Palaeo After Dark

The gang discusses two papers that look at the ecomorphology of Mesozoic swimming reptiles. The first paper investigates swimming strategies in various marine swimming reptile groups, and the second paper looks at changes in the skull of mosasaurs...

The gang discusses two papers that look at the impact of humans on bird populations. The first paper looks at the history of a condor nesting site in the Andes, and the second paper looks at the impact of artificial light on the circadian rhythms of...

The gang discusses two papers that study the paleoecology of the Ediacaran fauna. The first paper looks at environmental information that can be gleaned from the microbial mats these organisms lived on, and the second paper studies how different...

The gang discusses two papers about inferring life habit and ecology from extinct animals. The first paper summarizes the data for ichthyosaur birth to see if they really do preferentially come out tail first, and the second paper investigates a...

The gang discusses two functional morphology papers. The first paper looks at eye placement and skull morphology in Thylacosmilus and the second paper looks at the ungals of maniraptoran theropods. Meanwhile, James has milk filled “vegan” food,...

The gang discusses two papers that look at patterns of niche conservatism or niche evolution in the fossil record. The first paper looks at the pollen records of trees in Portugal to test if changing climate can explain modern tree distributions, and...

The gang discusses two papers that look at some Cambrian problematic fossils and find new clues that allow us to determine what groups they might belong to. One paper finds new evidence that some of these tube fossils in the Cambrian may be cnidarians...

The gang discusses two papers that use morphometric studies to investigate patterns of ecomorphy in the fossil record. Specifically, they look at two papers that investigate how morphology in sloths and pterosaurs changes over time, and how well these...

The gang discusses two papers that look at the body size of ancient animals. The first paper uses new metrics to estimate the size of the ancient fish Dunkleosteus, and the second paper looks at the various ways that theropod dinosaurs can get big or...

The gang celebrates their 10 year anniversary by talking about two papers on the same topic that are 10 years apart. Both papers take a critical look at how we define the “big five” mass extinctions and what this term means. Meanwhile, everyone...
