Summary: | In western Rajasthan, India, the Jodhpur Sandstone of the Marwar Supergroup has yielded a new Ediacaran fossil assemblage comprising macroscopic well-preserved specimens of Aspidella, Hiemalora, large Ediacaran discs, Tirasiana disciformis, Medusinites asteroides, Anfesta-like Ediacaran body fossils and microbial mat structures (Arumberia banksi, Kinneyia mat structures, wrinkle mat structures and other mat structures). The fossil record allows suggesting a broad correlation with the Fermuse Formation, Newfoundland, South Australia, White Sea of Russia and Norway, and regionally correlated with the Bhander Group of Vindhyan Supergroup and Krol Group of Lesser Himalaya. En el oeste de Rajasthan, India, la Arenisca de Jodhpur (Supergrupo de Marwar) ha librado un nuevo conjunto fósil ediacárico que comprende especímenes macroscópicos bien conservados de Aspidella, Hiemalora, grandes discos ediacáricos, Tirasiana disciformis, asteroides de Medusinites, fósiles de cuerpo blando ediacáricos similares a Anfesta y estructuras de tapices microbianas (Arumberia banksi, estructuras microbianas de tipo Kinneyia, estructuras microbianas arrugadas y otras estructuras microbianas). El registro fósil permite sugerir una amplia correlación con la Formación de Fermuse, Terranova, Australia meridional, el Mar Blanco de Rusia y Noruega, y la correlación regional con el Grupo de Bhander (Supergroup de Vindhyan) y el Grupo de Krol del Himalaya Interior. |
