Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. T. Carrano and S. D. Sampson 2008 | The original diagnosis of Ekrixinatosaurus includes both diagnostic and descriptive characters. This abelisaurid taxon appears to be diagnosed minimally by the presence of a posteriorly directed protuberance at the contact between the parietal and paroccipital process. Other features are shared by other abelisaurid taxa. However, other listed features are not accompanied by illustrations, so they have not been evaluated here, but further study may reveal them to be diagnostic. |
