RT Journal Article T1 Datos preliminares sobre la fauna de vertebrados (Pisces) del Devónico Inferior de Nigüella (Cadenas Ibéricas) T1 Preliminary data on the Lower Devonian vertabrate fauna (Pisces) from Nigüella (Iberian Chains) A1 Valenzuela Ríos, J. I. A1 Botella, H. AB Two sections at Nigüella (IberianChains) have provided a rich and varied Lochkovian and Pragian (Early Devonian) fish microremais association. The outstanding occurrence of two levels loaded with fish remains braking the Lochovian/Pragian boundary enables further paleontological characterisation of this boundary, and allows correlations with similar sequences in the Iberian Chains, Ardennes and Rhenish Slate Mountain PB Sociedad Geológica de España YR 1999 FD 1999 LK http://hdl.handle.net/10272/9855 UL http://hdl.handle.net/10272/9855 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 1 jun 2026
