Usually in the back of the jaw, on the upper edge, it is connected to all other jaw bones: dentary, angular, splenial and articular. It is often a muscle attachment site. It has been noted in dinosaurs.
上隅骨(英語:suprangular)是在除哺乳動物以外的大多數陸地脊椎動物中發現的一類顎骨。 通常在下顎後部的上邊緣,它與所有其他頜骨相連:齒骨、隅骨、夾骨和關節骨。 它通常是肌肉的附著點。
