Zama, meaning
City of Dawn, because it faces the sunrise. Tulum stands on a bluff facing east toward the
Caribbean Sea.
Tulúm is also the
Yucatán Mayan word for
fence,
wall Work conducted at Tulum continued with that of
Sylvanus Morley and George P. Howe, beginning in 1913. They worked to restore and open the public beaches. The work was continued by the
Carnegie Institution from 1916 to 1922, Samuel Lothrop in 1924 who also mapped the site, Miguel Ángel Fernández in the late 1930s and early 1940s, William Sanders in 1956, and then later in the 1970s by
Arthur G. Miller. Through these later investigations done by Sanders and Miller, it has been determined that Tulum was occupied during the late
Postclassic period around AD 1200. The site continued to be occupied until contact with the Spanish was made in the early 16th century. The site was abandoned by the end of the 16th century. In 2016, an underwater archaeological expedition led by Jerónimo Avilés exploring the cenote cave system discovered the skeleton of a female about 30 years of age that may be at least 9,900 years old. According to
craniometric measurements, the skull is believed to conform to the
mesocephalic pattern, like the other three skulls found in Tulum caves. Three different scars on the skull of the woman showed that she was hit with something hard and her skull bones were broken. Her skull also had crater-like deformations and tissue deformities that appeared to be caused by a bacterial relative of
syphilis. The newly discovered skeleton was 140 meters away from the
Chan Hol 2 site. Although archeologists assumed the divers found the remains of the missing Chan Hol 2, the analysis proved that these assumptions were erroneous in a short time. Stinnesbeck compared the new bones to old photographs of Chan Hol 2 and showed that the two skeletons represent different individuals. Due to their distinctive features, study co-researcher Samuel Rennie suggest the existence of at least two morphologically diverse groups of people living separately in Mexico during the transition from
Pleistocene to
Holocene. ==Architecture==
