Name: Ligabueino andesi
Name Meaning: Ligabue’s little one
First Described: 1996
Described By: Bonaparte
Classification: Dinosauria, Saurischia, Theropoda, Abelisauroidea
Not much is known about Ligabueino, as it is only known from fragments (namely fragments of a femur, ilium, pubis, phalanx, and vertebrae.) It was originally described as an adult specimen, however further reports have revealed it to be a juvenile. It is known from Patagonia, Argentina, from the Barremian stage of the Early Cretaceous, about 125 million years ago. It’s placement in the family tree is under debate. Some place it in Noasauridae, but since its so fragmented its unclear whether or not it is a Noasaur, and can only be confidently placed in Abelisauroidea. It has a somewhat peculiar foot morphology, similar to Noasaurus, which could support the former placement; however if it isn’t a Noasaur, then it shows that the foot structure could have arisen twice.
