Las pistas fósiles del Alcudiense superior en el anticlinal de Ibor. Consideraciones cronoestratigráficas

Abstract

New discovery of trace fossils in the Upper Alcudian of the Ibor anticline indicate that its supposed Precambrian age should be maintained but tentatively, due to the presence of scarce Lower Cambrian trace fossils although their distinction is problematic. Other fossil data, micro and macroflora, are also revised
