The Naranjal subsystem is part of Sistema Ox Bel Ha. Three prehistoric human remains have been found within the subsystem. The Jailhouse cenote, or Las Palmas, is the entrance to the locations of the Muknal and Las Palmas caves. The skeleton of an 18 to 20-year-old woman,Eve of Naharon, (13,454±117 calBP) was discovered at a location around 368 m (1,207 ft) away from the Jailhouse cenote entrance. The skeleton of a 44 to 50-year-old woman,Las Palmas Lady [es] (8,937±203 cal BP) was found at a location around 2 km (1.2 mi) away from the Jailhouse cenote entrance. The Muknal cave, part of the Naranjal subsystem, contained the remains of a 40 to 50-year-old man, theMuknal Grandfather (9,600 cal BP). Unlike the other two skeletons in the subsystem, theMuknal Grandfather shows evidence ofsecondary burial. Analysis of these skeletons suggests that Ox Bel Ha was likely used as an important site forritual burial.[5]
Muknalia minima mandible
A new genus and species of extinctpeccary,Muknalia minima, was identified from a fossil mandible found in the Muknal cave of the Ox Bel Ha system.[6] However, it was subsequently recognised that this was ajunior synonym of thecollared peccary.[7]
