1. Results of the discriminant function analysis (DFA) performed at the group-level on our personal datasets of 550 teeth belonging to 71 taxa gathered into 20 groupings along the first two canonical axes of maximum discrimination in the dataset (Eigenvalue of Axis 1 = 14.113, which accounts for 59.27% of the total variation; Eigenvalue of Axis 2 = 4.794, which accounts for 20% of the total variation) % of the theropod specimens were correctly classified in their respective groups, with NMS G and GLAHM a being classified as non-abelisauroid Ceratosauria and Troodontidae, respectively.

The absence of mesial and distal denticles was considered as inapplicable in this analysis. For silhouette acknowledgements, see Supplementary material 1.5.
