Ligabueino

Name: Ligabueino ‭(‬Ligabue’s little one‭)‬.
Phonetic: Lig-ah-bwen-o.
Named By: Jose Fernando Bonaparte‭ ‬-‭ ‬1996.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Dinosauria,‭ ‬Saurischia,‭ ‬Theropoda,‭ ‬Abelisuroidea.
Species: L.‭ ‬andesi‭ (‬type‭).
Diet: Carnivore.
Size: Estimated about‭ ‬70‭ ‬centimetres long for the holotype,‭ ‬though this is believed to be of a juvenile.‭ ‬Adults would have been larger.
Known locations: Argentina‭ ‬-‭ ‬La Amarga Formation.
Time period: Barremian/Early Aptian of the Cretaceous.
Fossil representation: Fragmentary post cranial remains,‭ ‬neural arches of vertebrae,‭ ‬femur,‭ ‬ilium,‭ ‬pubis,‭ ‬phalanx.

       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.
