Time-scaled phylogenies underpin the interrogation of evolutionary processes across deep timescales, as well as attempts to link these to Earth's history. By inferring the placement of fossils and us...

Continuous characters have received comparatively little attention in Bayesian phylogenetic estima- tion. This is predominantly because they cannot be modeled by a standard phylogenetic Q-matrix appro...

Abstract. Paleobiologists have long sought to explain how alternative modes of speciation, including budding and bifurcating cladogenesis, shape patterns o
