The location of this Late Classic Maya urban complex, along the east and west flow of trade, made the city a major transfer point for economic activities in the whole region.

Situated between the Poite and Pusilha rivers that run east and west, this may have impacted why the Maya urban complex was built there.

Pusilhá was also situated in the region to facilitate flow of goods and ideas from the central lowlands and southeastern periphery located in Honduras.

[3][4] The survey yielded dates and calendrical glyphs that were included in Sylvanus G. Morley's discussion work, The Inscriptions of Petén.

[6] This state of affairs has changed with research and excavations carried out by Geoffrey Braswell and the Pusilha Archaeological Project beginning in 2001.

The excavation that has continued to present has exposed three major areas at the center of Pusilhá to archaeological interpretation.

Transitions in ceramics, burials and construction, coupled with the usual cessation of inscriptions on stelae, indicate continued occupation at Pusilhá through to the post-classic.

Some say that research and excavation are at a very early stage and that more work is required to understand the place that Pusilhá holds in the greater Maya world.
