The 10-acre (four-hectare) site in Cambridgeshire was excavated by Oxford Archaeology East in preparation for a housing development by Bellway Homes.
“What makes this site really significant is we have evidence of early Saxon occupation mingled with the latest Roman remains,” said Mr Macaulay, deputy regional manager for Oxford Archaeology East.
Other finds include Saxon pottery, beads, worked antler and metalworking residues. Signs of Roman rural industry include a 15ft corn dryer and kilns, as well as Roman pottery.
According to Macaulay: “This a rare example of the Roman to Saxon transition in the east of England.”
The finds include eight roundhouses, some of which date back to about 100BC, three crouched human burials and 2,500-year-old pottery remains. There are in addition what looks like votive offerings including an equine burial.
