Ancestral Thames. The Ancestral Thames is the geologically ancient precursor to the present day River Thames. The river has its origins in the emergence of Britain from a Cretaceous sea over 60 million years ago. Parts of the river's course were profoundly modified by the Anglian (or Elsterian) glaciation some 450,000 years ago.
The River Thames (/ tɛmz / ⓘ TEMZ), known alternatively in parts as the River Isis, is a river that flows through southern England including London. At 215 miles (346 km), it is the longest river entirely in England and the second-longest in the United Kingdom, after the River Severn. The river rises at Thames Head in Gloucestershire and ...

An Ancestral Thames is thought to have come into being over 60 million years ago, during the post-Cretaceous uplift of Britain (an uplift which was tilted to the south-east). [4] The Brent, as a southward-flowing, left-bank tributary of the Thames, was formed as a result of the Anglian glaciation, which occurred about 450,000 years ago.
The majority of the evidence for Lower and Middle Palaeolithic occupation in East Anglia survives as redeposited flakes and tools recovered from river gravel deposits. These river gravels were laid by the ancestral Thames and Bytham River systems. Large quantities of artefacts were identified from gravel quarries during the 19th and early 20th ...
