Lithology and environment
Primary lithology:concretionary conglomerate
Lithology description: "The channel base contains large pebbles up to 10 cm in diameter. Above the pebbly layer is the main fossiliferous bed. It is about 30 cm thick and is gravelly. Above it is a layer of strongly cemented concretions. Each concretion is about 20 to 30 cm long and nearly 10 cm thick. These concretions are interpreted as the result of later water table action. They contain fossils as do several centimeters of the overlying layer."
Environment:coarse channel fill
