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.
