New paper published in Palaeontology by lab group member Bethany Allen on archosauromorph extinction selectivity across the Triassic-Jurassic boundary.

Allen, B.J., Stubbs, T.L., Benton, M.J. and Puttick, M.N. 2018. Archosauromorph extinction selectivity during the Triassic-Jurassic mass extinction. Palaeontology. Published online 1 October 2018, https://doi.org/10.1111/pala.12399

Allen phylogeny

The paper is published online and analyses the traits associated with extinction of archosauromorph tetrapods across the Late Triassic mass extinction. Allen et al. find evidence for a phylogenetic extinction signal where species were more likely to go extinct if their closest relatives also went extinct. However, they find no evidence of a correlation between extinction and body size. In conclusion, there is no evidence that body size or any other measurable trait had a bearing on extinction although the phylogenetic signal suggests selectivity on traits not measured herein.

This work formed the bulk of Bethany’s MSc thesis at the University of Bristol 2016/17.

Well done Bethany!
