TL;DR: A specimen-based protocol for selecting and documenting relevant fossils is presented and future directions for evaluating and utilizing phylogenetic and temporal data from the fossil record are discussed, to establish the best practices for justifying fossils used for the temporal calibration of molecular phylogenies.
Journal ArticleDOI
Bayesian Total-Evidence Dating Reveals the Recent Crown Radiation of Penguins
Alexandra Gavryushkina,Tracy A. Heath,Daniel T. Ksepka,Tanja Stadler,David Welch,Alexei J. Drummond +5 more
TL;DR: The FBD model and a model of morphological trait evolution are incorporated into a Bayesian total‐evidence approach to dating species phylogenies and it is shown that including stem‐fossil diversity can greatly improve the estimates of the divergence times of crown taxa.
Journal ArticleDOI

TL;DR: Recon reconstructing passerine evolutionary history and producing the most comprehensive time-calibrated phylogenetic hypothesis of the group, which suggests more complex mechanisms than temperature change or ecological opportunity have controlled macroscale patterns of passerine speciation.
Journal ArticleDOI
Fossil Evidence for Evolution of the Shape and Color of Penguin Feathers
Julia A. Clarke,Daniel T. Ksepka,Daniel T. Ksepka,Rodolfo Salas-Gismondi,Ali J. Altamirano,Matthew D. Shawkey,Liliana D'Alba,Jakob Vinther,Thomas J. Devries,Patrice Baby +9 more
TL;DR: The fossil reveals that key feathering features, including undifferentiated primary wing feathers and broad body contour feather shafts, evolved early in the penguin lineage, and analyses of fossilized color-imparting melanosomes reveal that their dimensions were similar to those of non-penguin avian taxa and that the feathering may have been predominantly gray-brown.
Journal ArticleDOI
Paleogene equatorial penguins challenge the proposed relationship between biogeography, diversity, and Cenozoic climate change
Julia A. Clarke,Daniel T. Ksepka,Marcelo Stucchi,Mario Urbina,Norberto P. Giannini,Norberto P. Giannini,Sara Bertelli,Sara Bertelli,Yanina Narváez,Clint A. Boyd +9 more
TL;DR: The most comprehensive phylogenetic analysis of Sphenisciformes to date, combining morphological and molecular data, places the new species outside the extant penguin radiation (crown clade: Speniscidae) and supports two separate dispersals to equatorial regions during greenhouse earth conditions.
