Literally means Earth lord
According to the Histoire du Mecihque, Quetzalcoatl and Tezcatlipoca tore apart Tlatecuhtli's body to form the surface of the Earth and out of her hair made the trees, and flowers and grasses, of her skin..flowers, of her eyes, wells and fountains and little caverns, of her nose valleys and mountains, and of her shoulders mountains. 
Tlaltecuhtli (with Tlazolli associations)
In artwork Tlaltecuhtli is associated both with death and life. At times she is depicted with disheveled hair containing such creatures from Mictlan as scorpions, spiders, and scorpions.
Tlaltecuhtli (with Malinalli associations)
These animals represent tlazolli (i.e., that which is rotten, used up, disintegrated,
and decayed - in short, matter out of place) At other times, Tlaltecuhtli is depicted with well groomed hair made of malinalli. In this depiction, Tlaltecuhtli represents lifeenergy as well as ever-rejuvenating fecundity, potency, and growth.
Depictions of Tlaltecuhtli in art thus indicate that Tlaltecuhtli is both the womb and tomb of all life. This idea is reinforced with the tonalpohualli tonalli
sign of Malinalli which at the base contains the bottom jaw of Miquiztli and from this base sprouts grass.
