The skull of Ekrixinatosaurus was boxy and proportionally shorter and deeper than most other large carnivorous dinosaurs.
The jaws also curved upwards, a trait shared with some other abelisaurs.
The skull is estimated to be approximately 83 cm long based on comparisons with Carnotaurus and Majungasaurus, and while Abelisaurus does not have a complete maxilla its preserved size is similar to that of Ekrixinatosaurus.
As in other abelisaurids, the facial bones, especially the nasal bones, were sculptured with numerous small holes and spikes.
In life, a wrinkled and possibly keratinous skin would have covered these bones.
The maxilla was short and contained 16 alveoli, some with short teeth that were flattened laterally with anterior and posterior serrations.
The maxilla of Ekrixinatosaurus also exhibits a dorsally projected ascending ramus and a short rostral ramus, suggesting a relatively high skull.
