An example would be the <br />Pa1eo-Indian economy which was based <br />Largely on the utilization of Large mam- <br />mals, and a technology especially marked <br />by the manufacture of large Lanceolate <br />projectile points. <br />Transhumanance Seasonal pattern of community movement <br />scheduled by upland-Lowland seasonal <br />resource availability. <br />Typologic Dating The use of extant typology (with dates <br />derived from excavated material) to infer <br />an approximate date for an artifact from <br />an undated or undatabLe material. <br />Typology Science of classifying artifacts by <br />form, techniques and technology, and <br />function (Crabtree 1972). <br />Type A series of attributes, which, in com- <br />bination, form a discreet recognizable <br />entity that has a distribution restricted <br />i.n time and space. • <br />42 <br />
