Glanosuchus

Name: Glanosuchus.
Phonetic: Glan-o-su-kus.

Species: G.‭ ‬macrops‭ (‬type‭)‬.
Diet: Carnivore.
Size: Skull about‭ ‬30‭ ‬centimetres long.‭ ‬Total body length roughly estimated to be about‭ ‬1.8‭ ‬meters long.

Time period: Wordian of the Permian.
Fossil representation: Skull.

       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.
