Although Tamarindito was located very close to the hostile Dos Pilas kingdom, it never possessed purpose-built defensive fortifications. The area between Tamarindito and Aguateca includes some of the most agriculturally fertile soils in the Petexbatún region and was intensively cultivated as evidenced by the remains of low boundary walls. The site also features sunken gardens, box terraces, and dams dated to the Late to Terminal Classic that formed part of an intensive agricultural system within the site core. Investigations have revealed that Tamarindito was the most productive agricultural centre in the Petexbatún region. It may have provided much of its agricultural production as tribute to Dos Pilas in the late 7th to early 8th centuries, since Dos Pilas itself had no agricultural production to speak of. The site is divided into two main groups, named as Group A and Group B. Both groups contained sculpture, including 3 stelae (2 inscribed and 1 plain), 3 hieroglyphic steps and two carved panels. The palace structures in Groups A and B appear to serve different functions, with those in Group A serving as elite residences and those in Group B appearing to serve administrative and diplomatic uses. The earlier construction phases of some palaces at Tamarindito exhibit different architectural styles and superior construction techniques to palaces at Dos Pilas in the 7th–8th centuries AD. The hillsides to the east of the site core were densely occupied with residential structures.
