Incorporating information on long gaps as priors on fossil sampling into the inference does not have a large impact on results! Plenty of very interesting follow-up questions remain, e.g on temporal and spatial scales, correlation, and fully extinct trees 3/n

Combining stratigraphic forward models with phylogenetic simulations, we found that total evidence analysis under the #FBD model is surprisingly robust to model violations of sampling - It doesn't matter if there are a few long or many short gaps in your fossil record! 2/n

Turns out sediment mixing is not as important as we think! most sediment is already well mixed - further increases in mixing do not change the resolution. Residence time in the surface mixed layer is more important

We find that the stratigraphic paleobiology of carbonates differs from that of siliciclastic systems, just as their sequence stratigraphy differs. The differences are due to high rates of in-situ sediment production: carbonates are born, not made! 2/n
