Capasso, L., D'Anastasio, R., Mancini, L., Tuniz, C. & Frayer, D. W. (2016). New evaluation of the Castel di Guido 'hyoid'. Journal of Anthropological Sciences, 94 231-235.


Castel di Guido is located west of Rome and part of the Aurelian formation (Mariani-Constantini et al., 2001) along with other sites such as Torre in Petra and La Polledrara (Mussi, 2001). These localities are a mixture of surface collections and excavated sites, all associated with Acheulean tools and dated to MIS 9. At Castel di Guido material was collected from the surface and excavations in an erosional channel (Mariani-Constantini et al., 2001; Mussi, 2001). The Middle Pleistocene dates suggest an age of around 400 ka. Direct associations between the human bones and tools do not exist, but based on the size and degree of fossilization the human material is thought to be late Acheulean. The deposits overlie tuffs from the Sabatini volcanic eruptions, dated at 431 ka+/-40 ka - 438 ka +/- 40 ka. so cannot be older than this. Originally six fragmentary bones were recovered from the site (Alciati et al., 2005) but Capasso, Michetti & D'Anastasio (2008) found additional material based on their survey of the material for post-mortem modifications.
