The bones of a woolly mammoth and woolly rhino which roamed Cambridgeshire 130,000 years ago have been unearthed during works on the A14.
The remains were found by workers excavating construction material from an ancient river bed near Fenstanton.
The roadworks have also uncovered Prehistoric Henges, Iron Age settlements, Roman pottery kilns, three Anglo-Saxon villages, and a deserted medieval village.
The discoveries will be sent to specialists in London for further study.
They were uncovered during works on the £1.5 billion A14 Cambridge to Huntingdon project which is due to open in December 2020.
