| rostral |
(1) Relating to the rostrum. (2) Towards the rostrum. Normally synonymous with "anterior," but not always. In discussing features of the human head, for example, "anterior" is ambiguous and "cephalad" (towards the head) is meaningless, so "rostral" is used instead. I am unsure what the opposite direction is. I've seen "caudal" used, but that's senseless as well as ambiguous. "Rostral" is reserved for head structures, and there is no tail (L. cauda = tail) on the head. ...

| rostral bone |
The rostral bone is a bone found only in ceratopsian dinosaurs (like Triceratops, Styracosaurus, and Protoceratops). This bone was located at the tip of the upper jaw. RUEHLEIA Ruehleia (named to honor the German paleontologist Hugo Ruehle von Lilienstern (1882-1946)) was an early plant-eating dinosaur that lived during the late Triassic period (the late Norian). This plateosaurid prosauropod was found in Germany. Ruehleia was named by Galton in 2001; the type species is R. bedheimensis.
