Geography
Country: Spain

State: Granada


Coordinate: 37.732952° N, -2.404772° W
Coordinate basis: estimated from map

Time interval: Early Pleistocene

Section: VM4-I

Unit order: below to above

Max Ma: 1.6

Min Ma: 1.37

Age basis: ESR

Geography comments: Venta Micena (VM) is located in the Guadix-Baza Basin near Orce in southeastern Spain

Unit C, which VM4-I 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-I is situated below VM4II in Interval C1 of Venta Micena's Unit C within micritic limestone of palustrine and lacustrine origin

Tooth marks are present on 4.4% of well-preserved bones at VM4-I with only 5% of marked bones exhibiting >5 tooth marks per bone

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

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
