Vega Ciencias de la Tierra Mexico Coahuila Konservat limestone Lagerstätte At El Rosario, 170 km WNW of Múzquiz in northern Coahuila, Mexico, alternating evenly layeredplaty limestone and fi ssile marly limestone of late Turonian-early Coniacian age (Late Cretaceous) containvertebrate fossils with exceptionally well-preserved anatomical details of their soft tissues, as well asabundant ammonoids, inoceramids and other invertebrates. Deposition was in an open marine shelfenvironment near the southern opening of the Western Interior Seaway, several hundreds of kilometerssouth of the North American coastline, in water depths of at least 50100 m. The present researchintends to highlight the enormous preservational potential of this new conservation deposit (Konservat-Lagerstätte) and to analyze the paleoenvironmental conditions present at this locality. Our preliminarydata suggest that the El Rosario fossil deposit is a combined result of anoxic bottom conditions, earlydiagenetic phosphatization, and rapid burial in a soft, micritic lime mud. 2005 artículo científico 1026-8774 https://www.redalyc.org/articulo.oa?id=57222313 en http://www.redalyc.org/revista.oa?id=572 Revista Mexicana de Ciencias Geológicas application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Ciencias Geológicas (México) Num.3 Vol.22 |
