Kem Kem Bone Spike/Horn?

[LordTrilobite]

Thanks I did not have that picture yet. And as you say. Abelisaurids are present in Kem Kem, but we don't know what the skulls look like. It's also much earlier than Carnotaurus, which is from the Maastrichtian, and it's also from a different continent. Though at the time of the Kem Kem beds South America and Africa were still fairly close to each other. When comparing with the Carnotaurus horns I find that the main difference seems to be from the front view with the horns of Carnotaurus being more fat. While in lateral and dorsal view it looks quite similar.
