Resumo
Trace fossils (Cruziana and Rusophycus) are described for the first time in the Carrascalejo beds. The stratigraphy of this unit is also modified; the conglomeratic basal beds are included in the underlying Precambrian series. An Upper Cambrian-Tremadocian age for the Carrascalejo beds is based both on trace fossils and on the regional stratigraphy
