English: Fossils of Xiphactinus audax with a Gillicus arcuatus within its stomach. The fossils were recovered from Gove County, Kansas in 1952 by George F. Sternberg (1883–1969). The fossils are on display at the Sternberg Museum of Natural History in Hays, Kansas and described as "probably the most photographed fossil specimen in the world."
