braincase
- n the part of the skull that encloses the brain
- Last year the 18,000-year-old remains of a 1-m-tall woman with a braincase the size of a chimpanzee were discovered at the same site.
- That loss in muscle strength, they say, allowed the braincase and brain to grow larger.
- Scientists determined the age of the skull, unearthed near Hofmeyr, South Africa, by testing the levels of radiation in sand that had filled the braincase.
