When beginning work on 'Dinosaur Planet', I was told we were to do an Abelisaurid. I assumed it would be the most popular of all, the Carnotaurus. So i began this sculpt. It turns out the Aucasaurus won out for the coveted position... and this guy relegated to the dustbin.
Still, they share a great many features, especially in the hindlimbs, so all was not lost. They have bizarre, twisted little arms that makes T. Rex look positively 'normal' in comparison.
