Sandstone, tan, fine- to medium- grained, 29. Shale, gray-black, with a few beds of tan, slightly pink, micaceous sandstone and sandy gray lime- stone, pelecypods and ammonites ( sp. indet.) present but poorly preserved 28. Limestone, dark to light gray, mas- sive, very hard, coquinoid beds of pelecypods alternate with irregu- larly bedded limestones that con- tain brachiopods, ammonites, pele- cypods, and gastropods. This unit is intermediate in its lithology be- tween the typical Bivalve bed as seen in Chhidru and the basal lime- stone beds at Narmia. Total Mittiwali Member 27. Sandstone, tan, calcareous, fine- grained, thin-bedded, with thin beds of black shale and gray lime- stone 26. Limestone, gray, massive, very hard 25. Limestone, dark gray, in beds 1-4 inches thick alternating with 1-4 inch beds of black, micaceous shale and siltstone; contains ammonites (Anasihirites) 24. Limestone, gray, fine-grained, in beds 1-3 inches thick; contains nu- merous poorly preserved ammonites 23. Sandstone, tan, fine-grained, thin- bedded, with a few thin interbeds of shale and gray limestone 22. LiiTiestone, gray, fine-grained; con- tains poorly preser\'ed ammonites 21.
