The find is now being managed by a team from the Dyfed Archaeological Trust and Sheffield University and they are in a race against time to ensure that the soil around the tomb is not eroded and washed out to sea.
Archaeologist Jenna Smith said her team was delighted with the discovery because all the skeletons were in good condition.
“With a long period of time, we expected the skeleton to be destroyed, but we were lucky that it was so good,” he said.
Excavation work started after number of bones found on the beach.
Experts at the University of Sheffield reveal that all human skeletons belong to men, women and children of all ages
