Legume (Mimosoideae) fossil woods from the late miocene (salicas formation) of northwestern Argentina

Six pieces of fossil wood from the late Miocene of Northwestern Argentina (Salicas Formation) are described. They are all assigned to Prosopisinoxylon anciborae Martínez based on the presence of the following diagnostic characters: vessels of two distinct diameter classes, simple perforation plates,...
