Vorona


Vorona berivotrensis 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 of the fossilised specimen is Late Cretaceous, probably Maastrichtian. V. berivotrensis is known from scattered remains, possibly from a single individual.
The phylogenic affinity of Vorona is hard to determine due to the fragmentary nature of the remains, mainly because the fossil shows a mix of basal avian features as well as some that seem very derived. 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.
