In Depth
Initially thought to be a tiny abelisauroid at the time of discovery, the lack of fusing in the vertebrae is now seen as proof that the individual which makes up the holotype is actually a juvenile. Unfortunately, because the remains of Ligabueino are so incomplete, it is hard to ascertain exactly what kind of abelisaur Ligabueino was, hence the more general description of it as an abelisauroid.
