Abstract
Se ha realizado un estudio bioestratigráfíco y sistemático de los materiales y fósiles del Cenomaniense superior-Turoniense inferior (Formación Picofrentes) en el área de Santamera y Riofrío del Llano, al norte de Guadalajara, España. Se han identificado los siguientes fósiles:el braquiópodo Phaseolina phaseolina (Valenciennes in Lamarck, 1819); los bivalvos Chlamys cf. guerangeri (Farge in Couffon, 1936), Cerastostreon flabellatum (Goldfuss, 1833), Ilymatogyra pseudoafricana (Choffat, 1902), Rhynchostreon suborbiculatum (Lamarck, 1801), Exogyra (Costagyra) olisiponensis (Sharpe 1850), ?Pholadomya sp., Granocardium cf. productum (Sowerby, 1832), ?Granocardium sp., Trigonarca sp., ?Proveniella sp. y Durania arnaudi (Choffat, 1891); los gasterópodos Harpagodes sp., Tylostoma ovatum Sharpe, 1849, Tylostoma torrubiae Sharpe, 1849, Drepanocheilus sp. y Cimolithium tenouklense (Coquand, 1862); los ammonites Vascoceras durandi (Thomas y Péron, 1889), Vascoceras kossmati Choffat, 1898, Choffaticeras (Choffaticeras) quaasi (Péron, 1904), Spathites (Jeanrogericeras) sp. Spathites (Jeanrogericeras) cf. obliquus (Karrenberg, 1935); y los equinoideos etragramma variolare (Brongniart, 1822), Holaster sp., Hemiaster bufo Desor, 1847, Hemiaster sp., Mecaster cf. scutiger (Forbes in Sharpe, 1849) y Mecaster palpebratus (Loriol, 1888). Las facies y las asociaciones identificadas revelan que estos materiales corresponden a paleomedios nerítico-litorales.
Resumen (otros idiomas)
A biostratigraphic and systematic study on the upper Cenomanian-lower Turonian (Picofrentes Formation) outcrops of the Santamera and Riofrío del Llano area (Guadalajara, Spain) is presented. The following taxa have been identified: the brachiopod Phaseolina phaseolina (Valenciennes in Lamarck, 1819); the bivalves Chlamys cf. guerangeri i (Farge in Couffon, 1936), Cerastostreon flabellatum (Goldfuss, 1833), Ilymatogyra pseudoafricana (Choffat, 1902), Rhynchostreon suborbiculatum (Lamarck, 1801), Exogyra (Costagyra) olisiponensis (Sharpe, 1850), ?Pholadomya sp., Granocardium cf. productum (Sowerby, 1832),?Granocardium sp., Trigonarca sp.,?Proveniella sp. and Durania arnaudi (Choffat, 1891); ; the gastropods Harpagodes sp., Tylostoma ovatum Sharpe, 1849, Tylostoma torrubiae Sharpe, 1849, Drepanocheilus sp. and Cimolithium tenouklense (Coquand, 1862); the ammonites Vascoceras durandi (Thomas and Péron, 1889), Vascoceras kossmati Choffat, 1898, Choffaticeras (Choffaticeras) quaasi (Péron, 1904), Spathites (Jeanrogericeras) sp. and Spathites (Jeanrogericeras) cf. obliquus (Karrenberg, 1935); and the echinoids Tetragramma variolare (Brongniart, 1822), Holaster sp., Hemiaster bufo Desor, 1847, Hemiaster sp., Mecaster cf. scutiger (Forbes in Sharpe, 1849) and Mecaster palpebratus (Loriol, 1888). The sedimentary facies and the fossil assemblages identified correspond to a neritic-coastal palaeoenvironment.
