Lithographie
The exposure at Sunetar 2 is ~26 m thick and, like the rest of the Ramnagar sequence, is characterized by reddish brown mudstones, paleosols, and occasional thin (<1 m), very fine-grained sands sandwiched between two massive sandstones. There is a pseudo- conglomerate layer composed primarily of mud pebbles, nodules, and concretions that becomes more concretionary at Sunetar 1, where it is full of coprolites and micro- and macro-vertebrate re- mains. The repetitive sequence of thick sandstones overlain by reddish brown mudstones and paleosols is pervasive throughout the Ramnagar sequence and represents major fluvial channels (sandstones) and overbank/floodplain deposits (mudstones/pale- osols). The new sivaladapid specimen was collected atop an ~5 m thick massive sandstone at the base of the Sunetar 2 exposure, but was derived from higher up in the sequence based on its preservation and lack of sand matrix.
