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 cal
BP) was discovered at a location around away from the Jailhouse cenote entrance. The skeleton of a 44 to 50-year-old woman, ''
(8,937±203 cal BP) was found at a location around 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, the Muknal Grandfather
(9,600 cal BP). Unlike the other two skeletons in the subsystem, the Muknal Grandfather'' shows evidence of
secondary burial. Analysis of these skeletons suggests that Ox Bel Ha was likely used as an important site for
ritual burial. However, it was subsequently recognised that this was a
junior synonym of the
collared peccary. ==See also==
