Map illustrating the location of Kapi (black star) relative to modern (dark green) and historical (light green) populations of lesser apes and the approximate distribution of early fossil apes in East Africa (blue triangles). Green triangles mark the location of previously discovered fossil gibbons. The new fossil is millions of years older than any previously known fossil gibbon and highlights their migration from Africa to Asia. Credit: Luci Betti-Nash.

Closeup of the stomach area of a fossil ichthyosaur, Guizhouichthyosaurus, showing part of the body of another large marine reptile. The ichthyosaur had swallowed its prey shortly before it died and was fossilized. This is the oldest known direct evidence of megapredation, or a large animal eating another large animal.

Phenotypic difference between each specimen for each landmark in the 11-module dataset and the mean skull shape.For each specimen, the mean landmark configuration is plotted with points coloured relative to the Procrustes distance between the position of that point in the mean shape and in that specimen. Warmer colours denote landmarks having higher displacement from the mean, and cooler colours are more similar to the mean shape. Data and code archived at www.github.com/rnfelice/Dinosaur_Skulls .
