RT Journal Article T1 Precisiones sobre la bioestratigrafía de las Clavatoraceas del Valanginiense de la Sierra del Pozo (Provincia de Jaén, SE de España) T1 Remarks about the biostratigraphy of the Valanginian Clavatoraceae from Sierra del Pozo (Province of Jaén, SE Spain) A1 García Cortés, Ángel A1 Ortiz, José Eugenio A1 Mansilla, H. A1 Torres, Trinidad de AB Some Clavatoraceae species have been determinated at the top of the Upper Berriasian-Lower Valanginian depositional sequence. Age determination is highly consistent with dating obtained through Foraminifera studies and formers carried out in the Maestrazgo Basin (Eastern Iberian Ranges). However, anagenetic transformation of Clavator harrisii (PECK) seems to take place during the Lower Valanginian and not later PB Sociedad Geológica de España YR 1995 FD 1995 LK http://hdl.handle.net/10272/13736 UL http://hdl.handle.net/10272/13736 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
