This study examines how extinction patterns varied over time in early vertebrates, showing shifts from clustered to overdispersed extinction during key evolutionary periods.

The paper introduces bifrost, an R package for detecting shifts in multivariate trait evolution across phylogenetic trees, using a greedy search and information-criterion weights.

This paper describes the oldest known tongue bite apparatus in a 310-million-year-old ray-finned fish, highlighting functional innovation in early actinopterygians.

This study examines the lower jaw morphology of Devonian ray-finned fishes using XCT, revealing new anatomical data and functional diversity.

This study examines the morphological and mechanical diversity of pelagiarian fish mandibles, finding that habitat depth and tooth type correlate with jaw shape, while mechanical advantage varies independently.

The paper examines phenotypic evolution in three living fossil lineages, finding varied evolutionary patterns across and within lineages, suggesting idiosyncratic processes rather than uniform change.

This paper describes new anatomical features of Dorsetichthys bechei using micro-CT scans, clarifying its relationships and ecology within early teleosts.
