A macroevolutionary analysis of European Late Upper Palaeolithic stone tool shape using a Bayesian phylodynamic framework [PDF]
Royal Society Open SciencePhylogenetic models are commonly used in palaeobiology to study the patterns and processes of organismal evolution. In the human sciences, phylogenetic methods have been deployed for reconstructing ancestor–descendant relationships using linguistic and ...

Combining fossil taxa with and without morphological data improves dated phylogenetic analyses. [PDF]
Biol LettThe fossilized birth-death (FBD) model has become an increasingly popular method for inferring dated phylogenies. This is because it is especially useful for incorporating fossil data into such analyses, integrating fossils along with their age ...

CladisticsIn the last decade, the Fossilized Birth–Death (FBD) process has yielded interesting clues about the evolution of biodiversity through time. To facilitate such studies, we extend our method to compute the probability density of phylogenetic trees of ...

PaleobiologyNon-technical Summary Integrating information from the fossil record allows us to obtain accurate age estimates for important events in the evolutionary history of living species and to study the dynamics of speciation and extinction in more detail.

The rise and fall of Varanopidae† (Amniota, Synapsida)
Frontiers in Earth ScienceStudy of past biological crises is now a timely topic because we may be in the midst of an anthropogenic mass extinction event. A skyline Fossilized Birth-Death (FBD) analysis of a dataset of 21 varanopid taxa, ranging in geological age from the mid ...

Distributions of extinction times from fossil ages and tree topologies: the example of mid-Permian synapsid extinctions [PDF]
PeerJ, 2021 Given a phylogenetic tree that includes only extinct, or a mix of extinct and extant taxa, where at least some fossil data are available, we present a method to compute the distribution of the extinction time of a given set of taxa under the Fossilized ...

The fossil record of camelids demonstrates a late divergence between Bactrian camel and dromedary [PDF]
Acta Palaeontologica Polonica, 2020 A new compilation of the Old World fossil record of Camelidae and a recent phylogenetic analysis allow a new assessment of the timing of the clade’s diversification.

Ignoring stratigraphic age uncertainty leads to erroneous estimates of species divergence times under the fossilized birth-death process. [PDF]
Proc Biol Sci, 2019 Fossil information is essential for estimating species divergence times, and can be integrated into Bayesian phylogenetic inference using the fossilized birth–death (FBD) process. An important aspect of palaeontological data is the uncertainty surrounding specimen ages, which can be handled in different ways during inference.

Inferring ‘weak spots’ in phylogenetic trees: application to mosasauroid nomenclature [PDF]
PeerJ, 2017 Mosasauroid squamates represented the apex predators within the Late Cretaceous marine and occasionally also freshwater ecosystems. Proper understanding of the origin of their ecological adaptations or paleobiogeographic dispersals requires adequate ...
