Environment
Lithology: marl
Taphonomic context: overbank deposit,paleosol,bird accumulation
Habitat comments: "The older vertebrate fossil assemblage (UA 540 m) is deposited in an animal burrow that was presumably produced by owls"
"The lithofacies and architectural element analysis suggest that the marly unit can be allocated to a meandering fluvial system"
"Levee deposits and floodplain fines are strongly bioturbated by root casts and burrows"
