Environment
Lithology: breccia
Taphonomic context: cave,rodent accumulation
Habitat comments: "an argillaceous silty-clay at the base and a pisolite-rich fossiliferous muddy calcareous breccia above"
"almost all the finds... are isolated teeth with characteristic wear facets and gnawed roots indicating porcupine activity" but "water was the major taphonomic agent responsible for the transport and deposition of the teeth" and "No arguments show that humans might have a possible role in the taphonomic process"
