Chenanisuchus

[1] Two specimens of C. lateroculi – OCP DEK-GE 262 (holotype, nearly complete skull with mandibular fragments) and OCP DEK-GE 61 (nearly complete skull) – come from the Sidi Chenane area in Morocco, which is Late Palaeocene (Thanetian) in age.

[3] Chenanisuchus lateroculi is referred to Dyrosauridae by Jouve et al. (2005), based on three morphological characters: Chenanisuchus lateroculi has an estimated adult length between 4 and 4.5 meters, based on the 60 centimeter long skull.

The teeth on the maxillae and dentaries are short and robust, but sharp.

[2] Studies of the inner ear morphology of Malian dyrosaurids suggest that they were adapted for walking on the sea floor as opposed to swimming, a hypothesis supported by the apparent lack of adaptations for swimming seen in other marine crocodyliforms (e.g. Metriorhynchidae) such as paddlelike fins.

[4] This mode of subaqueous locomotion is suggested to have contributed to the survival of dyrosaurids such as Chenanisuchus across the K-Pg boundary.
