Known from very incomplete material (an ilium). It was first described as a giant theropod, but later work has suggested it may be a titanosaurian sauropod. Its exact affinities are uncertain, and the material may be too incomplete to diagnose it confidently. The etymology of the place name and the exact formation and age are given from memory, so treat them with some caution.
