Includes fossils? | Y |
Lithology description: "Occurs in greenish-gray marls and biomorphic (organogenic-detrital) limestones of the third facies zone, which permits assignment to BA 3. Disarticulated values of Isorthis ovalis are abundant and articulated specimens rare, which suggests a normal level of turbulence (the specimens are commonly well preserved). | |
Environment: | marine indet. |
Taphonomy
