:''For the commune in Botoşani County, Romania, see Vorona, Botoșani.'' ''Vorona'' ( ; Malagasy for "bird", ''V. berivotrensis'', "from Berivotra") is a monotypic genus of prehistoric birds. It was described from fossils found in a Maevarano Formation quarry near the village of Berivotra, Mahajanga Province, Madagascar. The age is Late Cretaceous, probably Campanian (70.6–83.5 mya). ''V. berivotrensis'' is known from scattered remains, possibly from a single individual (UA 8651 and FMNH PA715). The phylogenic affiliation of ''Vorona'' is hard to determine due to the fragmentary nature of the remains, mainly because the fossil shows a mix of primitive avian features as well as some that seem very modern. ''Vorona'' might be a primitive ornithuromorph. ''Vorona'' is sometimes confused with the dromaeosaur ''Rahonavis ostromi'', a fossil of which was found in the same location. This confusion has led to the common misconception that ''Vorona'' had a deinonychosaur-like sickle claw on each foot. ==References== * Forster, Catherine A.; Chiappe, Luis M.; Krause, David W. & Sampson, Scott D.
