Figure 1 The dinosaurs that got away. Family tree of dinosaurs and close relatives, showing victims (in red) and survivors (in green) of the end-Cretaceous mass extinction. Timescale values are in millions of years; thick dark red line denotes the mass extinction at the Cretaceous–Paleogene boundary; thick line sections of branches indicate direct fossil evidence and thin lines are temporal distributions implied by phylogenetic ghost lineages; Cz=Cenozoic interval after the extinction. Silhouettes in the lower part of the image denote approximately where important features of modern birds evolved on the phylogeny. Species silhouettes at the top of the image are from phylopic.org and designed by (from left to right), Nobu Tamura, Anne Claire Fabre, T. Michael Keesey, Steven Traver, Andrew A. Farke, Matt Martyniuk, Scott Hartman, Mathew Wedel, Steven O’Connor/T. Michael Keesey, Brad McFeeters/T. Michael Keesey, Scott Hartman, T. Michael Keesey, Matt Martyniuk, Nobu Tamura/T.
