Environment
Lithology: conglomerate
Taphonomic context: fluvial deposit
Habitat comments: the sequence is composed of a debris flow, presumably meaning it is fluvial
the fossils are mostly from the second of four levels, which is a conglomerate supported by bioclasts and cemented with limestone
however, some fossils are from the underlying first level, which is clayey-sandy gravel
there is no discussion of accumulation agents
