The fossil avifauna of the tar seeps Las Breas de San Felipe, Matanzas, Cuba Author Suárez, William text Zootaxa 2020 2020-05-22 4780 1 1 53 journal article 21918 10.11646/zootaxa.4780.1.1 af0a7e60-adc6-4896-8544-63725501fa13 1175-5326 3856493 D6CC1683-8BF0-4ABF-ABFE-3EC63E66AE5C † Ornimegalonyx sp. ( Figure 12 : I–J) Referred material. San Felipe II : Proximal half of right femur, MNHNCu 75.4714; distal half of fragmentary left femur, MNHNCu 75.4715; proximal fragment of right tarsometatarsus, MNHNCu 75.4716; distal fragment of right tarsometatarsus, MNHNCu 75.4717. Description. Differs from specimens of Ornimegalonyx oteroi present in this deposit, and from other fossil localities, by its smaller size. The elongated shaft of the tarsometatarsus in the genus Ornimegalonyx (see Arredondo & Olson 1994 , fig. 1) separates it from Bubo osvaldoi Arredondo & Olson, 1994 , a somewhat smaller Cuban strigid owl not identified so far from these tar seeps. Comments. Remains of the genus Ornimegalonyx of similar size to the specimens recorded herein, are also known from eastern Cuba (Suárez unpubl. data).
