We describe a partial dyrosaurid skeleton recently prepared out of a limestone 15 block discovered in the 1930s from Danian strata along the Atlantic coast of Senegal. The 16 specimen, from a single individual, comprises nicely preserved elements of the appendicular 17 and axial skeleton from the abdominal and sacral region, which enables us to refine our 18 knowledge on some postcranial characteristics of the Dyrosauridae. Although Dyrosauridae 19 are abundant in early Eocene deposits of North Africa, the present discovery in the Danian of 20 Senegal fills a patchier record early after the K/Pg boundary and provides an important 21 comparative datapoint with the few other Danian dyrosaurid records such as Atlantosuchus 22 from nearby Morocco or Guarinisuchus and Hyposaurus from Brazil and the USA, 23 respectively. 24 25 26 27
