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 80 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.
