This structure is more readily explained as an elongate, gently tapering body fossil, than as a trace fossil. |
Cheirotherium trace fossil, displayed in Oxford University Museum of Natural History. |
The high trace fossil abundance but low diversity in the heavily bioturbated horizons points to a relatively restricted or stressed environment. |
However, the identification of the pinnate branching trace fossil Dendrorhaphe isp. |
In accordance, this trace fossil would be indicative of the surface soil horizon. |
The normal feeding and swimming behaviors indicated by the trace fossil indicate temporarily oxygenated benthic conditions in the deepest part of Fossil Lake, counter to most paleoecological interpretations of this deposit. |
