I have uncovered a second paper of interest today written by Roberto Ebner, a medical doctor, and Leonardo Salgado. In this paper Ebner and Salgado used CT scans to measure the optic canal of Abelisaurus. They note in the paper that the scanning has led them to think that Abelisaurus had only a few hundred grams of brain matter and that, despite poor preservation on one side of the skull, the optic canals were scanned and imaged quite nicely; though it does not say to what purpose beyond scanning them. The scan appears below.
