Elevated Cranial Sutural Complexity in Burrowing Dicynodonts
Frontiers in Ecology and Evolution, 2021 Relationships between the complexity of the cranial sutures and the inferred ecology of dicynodont synapsids are explored. Simple complexity indices based on degree of sutural interdigitation were calculated for 70 anomodont species and indicate that the
