The crania of individuals who lived in the Yucatán Peninsula during the late Pleistocene show a high degree of anatomical diversity among them, and their skull shapes differ from that of other North American populations of the time.
A roughly 99-million-year-old piece of amber from northern Myanmar contains the skull of what appears to represent the smallest known dinosaur of the Mesozoic era.
