Ligabueino (meaning "Ligabue's little one") is a genus of abelisauroidtheropoddinosaur named after its discoverer, ItaliandoctorGiancarlo Ligabue. It is known only from an extremely fragmentary specimen, measuring 79 cm (2.6 ft) long, found in the La Amarga Formation.[2] In spite of initial reports that it was an adult, the unfused vertebrae indicate that the specimen was a juvenile.[3] It was a theropod and lived during the Early CretaceousPeriod (Barremian to early Aptian), in what is now Patagonia.[4] Contrary to initial classifications that placed it as a member of the Noasauridae, Carrano and colleagues found in 2011 that it could only be placed with any confidence in the group Abelisauroidea.[3] In 2024, Ligabueino was recovered as a sister taxon of Berthasauridae and Abelisauroidea.[5]
