Environment
Lithology: siliciclastic (mixed)
Taphonomic context: fluvial deposit
Habitat comments: "They are found in a small outcrop (~20 m thick) of alternating light and dark lutites with occasional limestone beds, overlain by a thick conglomerate layer with erosive base, corresponding to a channel deposit. Small-mammal remains have been recovered from two dark lutite levels"
