This study investigates how stratigraphic gaps affect phylogenetic inference using a simulation framework and finds that total-evidence analysis is robust to gap distribution but dominated by morphological character data.

This study combines morphological and taxonomic data to improve dated phylogenetic analyses of trilobites, resulting in more accurate divergence time estimates and stratigraphically congruent topologies.

The paper assesses the adequacy of morphological models in phylogenetics using posterior predictive simulations and finds that current Mk model variations perform adequately but no single model is universally best.

The paper shows that estimating species age from phylogenetic trees is error-prone due to sampling biases and speciation assumptions, and proposes a probabilistic model to improve accuracy.
