Larrasoaña et al. 2006: fossil localities of the Tudela Formation assigned to the "Ramblian" continental stage. The lower boundary of the Ramblian is placed at the lower part of chron C6r (ca. 20.4 Ma), and the boundary between the lower and upper Ramblian is located at the middle of chron C6n (ca. 19.6Ma). The upper boundary of the Ramblian, and hence the base of the Aragonian, is placed at the upper middle part of chron C5Cr (16.8–17Ma). A revised calibration of European mammal zone MN3 suggest the lower boundary of zone MN3 is placed at the boundary between chrons C6r and C6n (ca. 20.1Ma), and its upper boundary is located at the upper middle part of chron C5Cr (16.8–17Ma).
Lithology and environment
Primary lithology:gray,blue marl
Includes fossils?Y
Lithology description: Blue to gray marls
Environment:mire/swamp
Geology comments: The lithological features and sedimentary structures observed in the Bardenas sites suggest that the vertebrate remains were deposited in the distal areas of an alluvial system. The presence of mudcracks and bioturbation traces in limestones suggests a shallow, not permanent water environment. This is indicative of a wetland.
