Sabalites is an extinct genus of palm. Species belonging to the genus lived in the late Cretaceous to Miocene and have been found in South America,[1] North America, Europe, and Asia.[2][3] The genus is characterized by its costapalmate leaves,[4] which consist of a radial fan of leaves that have individual pronounced midribs (costa).
