Beesiiwo (meaning "big lizard") is a genus of hyperodapedontine rhynchosaur known from the Late Triassic Popo Agie Formation in western Wyoming, United States. The type and only species is Beesiiwo cooowuse, known from four fragmentary jaw bones.
Beesiiwo is known from four specimens which were referred to B. cooowuse in 2023 by Fitch et al. (2023). The holotype, USNM 494329 consists of a fragment of a left maxilla, and a left dentary,[1] it was previously assigned to cf. "Hyperodapedon" sanjuanensis by Lucas et al. (2002).[2] The additional specimens, UWGM 7027, UWGM 7028, and TxVP 46037.1, consist of fragments of two right maxillae, and a left maxilla.[1] The authors state that an additional specimen, NSM018GFF009.003 (which had been referred to Oryctorhynchus bairdi by Sues et al. (2020)[3]) was not support as belonging to O. bairdi, and is more closely affiliated with Beesiiwo.[1]
