RT Journal Article T1 Pistas fósiles en la «Serie de Carrascalejo». Implicaciones cronoestratigráficas T1 Trace fossils in the «Carrascalejo Beds». Chronostratigraphic implications A1 García Hidalgo, J. F. AB 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 PB Sociedad Geológica de España YR 1992 FD 1992 LK http://hdl.handle.net/10272/14139 UL http://hdl.handle.net/10272/14139 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
