What Wikipedia says

Lingulata is a class of brachiopods, among the oldest of all brachiopods having existed since the Cambrian period (538.8 million years ago). They are also among the most morphologically conservative of the brachiopods, having lasted from their earliest appearance to the present with very little change in shape.
