These early humans suffered local extinction in Northern Europe during the great ice age known as the Anglian glaciation 450,000 years ago, but re-established themselves as the climate grew warmer again in the following Hoxnian interglacial
Various dating methods, including biostratigraphy (Parfitt), lithostratigraphy (Lewis), aminostratigraphy (Bowen) and, with caveats, OSR (Rhodes), suggest that the site dates to the Hoxnian interglacial
It occurred in the Hoxnian interglacial
and was about 250,000 years old; dating was typological or relative to pollen-based terrestrial sequences; two interglacials separated three full-on glaciations, and well made ovates were a stage in a developmental trajectory.
At the time of the Hoxnian interglacial
Britain formed part of continental Europe, but, in terms of comparative archaeology, only British Lower Palaeolithic sites are mentioned.
