15 Feeding The cheek teeth of Basilosaurus retain a complex morphology and functional occlusion. Heavy wear on the teeth reveals that food was first chewed then swallowed (Wikipedia). Analyses of the stomach contents of B. cetoides has shown that this species fed exclusively on fishes and sharks, while bite marks on the skulls of juvenile Dorudon have been matched with the dentition of B. isis, suggesting a dietary difference between the two species, similar to that found in different populations of modern killer whales (Wikipedia).

He visited the Qasr el-Sagha Formation in 1884 and 1886 and missed the now famous Zeuglodon Valley with a few kilometers.
