Abstract

The Cambrian explosion of life is perhaps the most important event since the appearance of life on Earth some 4.000 million years ago. The explosion was a controversial issue since the 19th century and still provokes intense research and polemics. In this paper we describe some late Precambrian biotas, along with the Cambrian explosion itself; its probable causes are also discussed. Cambrian sites bearing exceptionally-preserved fossils are key for understanding this major bioevent. Two of them are herewith synthesised: the Burgess Shale in Canada and Murero in Spain; as for the latter, its utility as didactic resource is also given.
