       Named from a partial skull,‭ ‬Glanosuchus is still one of the more interesting therapsid predators of the Permian.‭ ‬The ear structure of Glanosuchus reveals the early stages towards a development of an inner ear,‭ ‬something that later mammals would possess.‭ ‬This would mean that Glanosuchus likely had better hearing than earlier synapsids,‭ ‬though not yet as good as later mammals.‭ ‬There are also ridges within the nasal passage of the‭ ‬snout,‭ ‬features that would have‭ ‬prevented moisture loss through respiration.‭ ‬Given the therapsid lineage of Glanosuchus,‭ ‬these ridges may indicate a faster rate of respiration,‭ ‬which in turn might denote a warm blooded metabolism.
