The Middle Cambrian (also known as Albertan, Acadian, St. David's, or Saint David's) is the second of three geological epochs of the Cambrian period. It spans the time between 513 ± 2 Ma and 501 ± 2 Ma (million years ago). The strange organisms of the Burgess Shale fossil site lived during this epoch. The Middle Cambrian is divided into two unnamed ICS stages.
