Geography comments: Bolomor Cave is situated on the "southern slope of the Valldigna valley, approximately 2 km southeast of the town of Tavernes"
The coordinates entered are based on Tavernes de la Valldigna as that was the closest possible estimate
"The karst deposit of Bolomor Cave has been dated by Amino Acid Racemization (AR) and Thermoluminescence (TL) to between MIS 9 and MIS 5"
No specific date is provided for Level IV though it is situated multiple layers above Level XII which is dated to 0.152 Ma +/- 0.023 Ma and two layers below Level II which is dated to 0.121 Ma +/- 0.018

Environment
Lithology: siliciclastic (mixed)
Taphonomic context: carnivore accumulation,cave,human accumulation
Habitat comments: "Bolomor cave is a karst cavity opened to the exterior approximately 500 ka, as a consequence of the erosion of the ravine where is placed"
"The sedimentary sequence of Bolomor Cave consists mainly of allochthonous material of colluvial origin. In addition to these deposits, there are other autochthonous sediments of gravitational origin from the roof subsidence, due to tectonics or weathering processes."
Cut marks are identified on 7.18% of bone remains mainly on the limb bones of medium and large-sized taxa, as well as birds, tortoises, and O. cuniculus
Evidence of burning was found on 61.54% of remains at Level IV mostly on lagomorphs and tortoises
