There are large supratemporal fossae, bounded below by supratemporal arcades.
They are connected by the supratemporal with the epi-otic and opisthotic regions of the cranium.
The supratemporal is thus wedge-shaped and located between the parietal and the postorbital.
These lie below and to the outer side of the supratemporal fossae.
The supratemporal fossae are small, and open posteriorly, the lateral temporal fossae are very large.
