Vorona

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. At least two studies recovered it as part of Enantiornithes, however.
"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.
