Resumen:
The braincase of the Tyrannosaurus rex
known as Scotty (RSM P2523.8) is well preserved, and provides
important, new information. Unfortunately, the endocranial cavity is
still filled with sediment so that internal characters (such as the
shape of the floccular recess and the relative positions of internal
cranial foramina) cannot be observed and compared. Most of the sutures
between the bones of the braincase cannot be seen because of fusion,
indicating that Scotty is an adult individual. In this contribution,
the braincase is described and compared with the braincase assigned to
another tyrannosaurid, Daspletosaurus (TMP 2001.36.01).
