Chromeornis funkyi

Chromeornis is an extinct genus of longipterygid enantiornithean bird known from the Early Cretaceous Jiufotang Formation of China. The genus contains a single species, Chromeornis funkyi, known from most of an articulated skeleton preserved on a slab and counterslab. This specimen was found with a mass of gastroliths in the esophagus, but these were likely not the gizzard stones expected in the gizzard of some birds. Instead, they may have been the result of an illness, with the animal dying after attempting to regurgitate them.
