Dating Fossils – How Are Fossils Dated?

Alexandra Gavryushkina, Tracy A. Heath, Daniel T. The total-evidence approach to divergence time dating uses molecular and morphological data from extant and fossil species to infer phylogenetic relationships, species divergence times, and macroevolutionary parameters in a single coherent framework. Current model-based implementations of this approach lack an appropriate model for the tree describing the diversification and fossilization process and can produce estimates that lead to erroneous conclusions. We address this shortcoming by providing a total-evidence method implemented in a Bayesian framework. This approach uses a mechanistic tree prior to describe the underlying diversification process that generated the tree of extant and fossil taxa. Previous attempts to apply the total-evidence approach have used tree priors that do not account for the possibility that fossil samples may be direct ancestors of other samples, that is, ancestors of fossil or extant species or of clades. The fossilized birth—death FBD process explicitly models the diversification, fossilization, and sampling processes and naturally allows for sampled ancestors.

The Collective

Our video calls were ending with weeping, and I felt the winter outside my window settling upon my hope in Christ. Lamentations 3 was where God met me, and it was there we wrestled in prayer. Before you read and pray this prayer, study Lamentations 3. His grief is raw, but his hope is real. I know that you are good to those who wait for You, but I am struggling to believe anything good can come from this. This pain feels too severe, too cruel to be worth the results. My endurance and my hope have faded into oblivion. Where are you, God? But this I call to mind, and therefore I have hope: Your steadfast love never ceases. Your mercies never come to an end — they are new every morning.
