“…(figured in Villanueva-Amadoz et al, 2010), the main body of the pollen grain is much smaller than the reticulum, very similar to the situation in Afropollis Doyle, Jardiné et Doerenkamp but unlike the pollen grains found with the Canrightia floral structures.…”

“…The occurrence of Lower Albian ammonoids in the lower part of the Escucha Formation is probably linked to the strong transgressions corresponding to the global sequences Ap6, Al1, Al2 and/or Al3 of Handerbol et al (1998). The continental deposits of the middle and upper parts of the formation have been assigned to the upper part of the Lower Albian and the entire Middle Albian based on the palynological studies of Villanueva-Amadoz et al (2010. The fluvial sandstones of the Utrillas Formation overlie the Escucha Formation.…”

A review of the stratigraphic distribution of ammonoid species in the Lower Cretaceous (Hauterivian-Albian) of the Maestrat Basin (E Spain) was carried out. The specimens were mainly collected in the field by us and are stored in university or museum collections. Specimens from private collections and figured in the literature were also studied. We recognized 73 species that are distributed, in accordance with the latest version of the standard Mediterranean ammonite zonation for the Lower Cretaceous, in 14 ammonite zones: Acanthodiscus radiatus, Crioceratites loryi, Lyticoceras nodosoplicatum (Lower Hauterivian); Pseudothurmannia ohmi (Upper Hauterivian); Imerites giraudi (Upper Barremian); Deshayesites oglanlensis, Deshayesites forbesi, Deshayesites deshayesi, Dufrenoyia furcata (Lower Aptian); Epicheloniceras martini, Parahoplites melchioris, Acanthohoplites nolani (Upper Aptian); Leymeriella tardefurcata and Douvilleiceras mammillatum (Lower Albian). The recognition of these biozones allows a precise age calibration of the Maestrat Basin's lithostatigraphic units that contain ammonoids as well as an associated indirect age calibration of the formations without ammonoids. Consequently, this report provides an updated, comprehensive and precise biostratigraphic framework, which aims to become a reference for the analysis of the Lower Cretaceous strata of the Maestrat Basin. The results are also relevant for the analysis of coeval ammonite-bearing sedimentary successions found in other Tethyan basins.Keywords: ammonites, Lower Cretaceous, biostratigraphy, Maestrat Basin, Spain Resumen En este trabajo se ha realizado una revisión detallada de la distribución estratigráfica de las especies de ammonoideos del Cretácico inferior de la Cuenca del Maestrazgo (Este de España). Los ejemplares recolectados, principalmente por los autores, han sido depositados en colecciones universitarias y museísticas. Además hemos estudiado los ejemplares de colecciones privadas y figurados en la literatura.

El reconocimiento de estas biozonas permite precisar la edad de las unidades litoestratigráficas que contienen ammonites y también una calibración indirecta de las formaciones que no contienen ammonites. En consecuencia este trabajo proporciona un marco bioestratigráfico actualizado, exhaustivo y preciso que pretende ser una referencia para el análisis estratigráfico del Cretácico infe...

“…The precise age of these deposits is controversial; the Escucha Formation is diachronous. Recently, a middle Albian age was proposed for the San Just outcrop on the basis of angiosperm pollen (Villanueva-Amadoz et al, 2010), and it was included in the El Regachuelo Member. The Peñacerrada outcrops have yielded a diverse palynomorph assemblage consisting of spores, gymnosperm, and angiosperm pollen grains, in addition to dinoflagellate cysts and acritarchs, suggesting an Early Albian age (Alonso et al, 2000;Barrón et al, 2001).…”

A new family of microhymenopteran wasps is described and figured from three new species discovered in Cretaceous amber of Spain (Albian) and New Jersey (Turonian). Spathiopterygidae Engel and Ortega-Blanco, new family, is allied to the Diapriidae and Maamingidae (Proctotrupomorpha: Diaprioidea), sharing with these families putatively derived features relative to Monomachidae. The family contains three genera and three species, all new: Spathiopteryx alavarommopsis Engel and Ortega-Blanco, new genus and species, and Myamaropsis turolensis Engel and Ortega-Blanco, new genus and species, both from the Early Cretaceous (Albian) of Spain, and Spathopria sayrevillensis Engel, Ortega-Blanco, and Grimaldi, new genus and species, from the Late Cretaceous (Turonian) of New Jersey. Spathopria sayrevillensis is reconstructed using x-ray synchrotron microtomography. In addition, a peculiar new genus and species, Iberopria perialla Engel, Ortega-Blanco, and Delclòs, of stem-group Diapriidae is described from Spanish
