Geography comments: Venta Micena (VM) is located in the Guadix-Baza Basin near Orce in southeastern Spain
Unit C, which VM4-II falls into has been dating using combined U-Th/ESR dating methods to a mean age of 1.37 +/- 0.25 Ma and has been refined/extended based on biochronology up to ~1.6 Ma

Environment
Lithology: limestone
Taphonomic context: carnivore accumulation,lake deposit
Habitat comments: "VM4 would have been located near the edge of a lacustrine environment centered around the relatively large and saline endorheic Baza lake"
VM4-II is situated above VM4I in Interval C1 of Venta Micena's Unit C within micritic limestone of palustrine and lacustrine origin
Weathering alterations are scarce, implying low levels of subaerial exposure
Evidenced by tooth marks, bone breakage patterns, and other taphonomic evidence it is probable that VM4 represents an open-air site where "multiple carnivores interacted with herbivore carcasses", mainly felids, hyaenids, and possibly canids
Tooth marks are present on 1.9% of well-preserved bones at VM4-II with only 5% of marked bones exhibiting >5 tooth marks per bone
The assemblage is not thought to be accumulated as the result of activity by one particular taxon, but rather through the input of "multiple agents"
Taphonomic research is still ongoing as is the debate on accumulation at Venta Micena 4
