Fifty miles north of Mazatlan in Sinaloa State, north west Mexico, there is a beach known as Las Labradas where the rocks are covered in over 600 petroglyphs. Now Mexican investigators have uncovered archaeological sites in the vicinity dating to the Archaic period (2500-1000 BCE) along with another later site that may provide clues to the creators of the Las Labradas petroglyphs.
V filed teeth and cranial deformation
To date there are 22 locations around the rocky outcrop with evidence of human activity, of which, between 2010 and 2012, four were studied: The Flower of the Ocean, The Sprig, Lomas del Mar and Arroyo La Lomita.
Joel Santos Ramirez, from the National Institute of Anthropology and History (INAH) and his team discovered an Aztatlán (750-1250 CE) site, consisting of ceramics and a multiple burial of five individuals: two adult males, two adolescents (one male and one female) and a possible female infant.
All except the child have dental mutilation with “V” filed teeth and two had cranial deformation, cultural practices that were common among the peoples of Sinaloa.
The physical characteristics of the burial allowed Joel Santos to attribute the site to a local culture fitting into the chronology of the western Aztatlán, corresponding to between 1250 and 750 years ago, contemporary with the Postclassic Mesoamerican ‘Chicayota‘.
Relating rock art to settlement
Among the pottery discovered was one piece, decorated with concentric circles which is one of the symbolic elements present in many of the Las Labradas petroglyphs, though it is still difficult to relate to the rock engravings to the settlements under investigation and whether they belong to the earliest inhabitants of Sinaloa or the later Chicayota culture.
Ramirez suggests that it may even be both cultures as people who created rock art may have been following older traditions.
At the Lomas del Mar site, more pottery and shell debris from the Aztatlán period was discovered and also at Arroyo La Lomita, located 3 kilometres inland, though this time the ceramics and artefacts were associated with petroglyphs.
Oldest known occupation in northwest Mexico
In addition to these later sites, Ramirez has found another which will “change the timeline on the antiquity of human occupation in the northwest of the country”.
A wonderful group of petroglyphs called Las Labradas is on a beach near the Barras de Piaxtla. The petroglyphs or rock paintings are the voices of ancient testimonies, of hundreds of years of mythological traditions made by the ancient peoples of the American continent. They are beautiful abstract and symbolic expressions for the continent’s new inhabitants.
The petroglyphs are associated with the supernatural. They were an important way to communicate with the gods, and were made within a specific context of rituals and ceremonies, in which, generally, people asked for rain, a good harvest, a good hunting season, etc.
Archeologists and specialists from the National Institute of Anthropology and History of the Mexican government have registered a total of 50 places in the state of Sinaloa alone. These sites feature cave paintings and stone carvings and in the future archeological investigation will be able to work out more and better explanations of these stories told in stone. This would indubitably shed more light on the type of men who carved them and show what use this knowledge could mean to us and to future generations.

Asteroids cause dozens of nuclear-scale blasts in Earth’s atmosphere 2014 04 22
Asteroids caused 26 nuclear-scale explosions in the Earth’s atmosphere between 2000 and 2013, a new report reveals.
Some were more powerful – in one case, dozens of times stronger – than the atom bomb blast that destroyed Hiroshima in 1945 with an energy yield equivalent to 16 kilotons of TNT.
Most occurred too high in the atmosphere to cause any serious damage ...
‘Editing DNA’ to eliminate genetic conditions now a reality 2014 04 22 Scientists have employed a revolutionary genome-editing computer technique that accurately identifies one faulty genetic “letter” among billions and effortlessly repairs a genetic condition in animals, paving way for human trials.
The success, by MIT in Boston, is the latest achievement in the field of genome editing that has been catapulted into the spotlight through a technology that can pinpoint genetic faults ...
