The collection at the Lajedo de Soledade, Apodi, RN, contains fragments of the Paleozoic Era animals and some pieces of lithic and ceramic material that were used by the various indigenous tribes that inhabited this territory, serving as a technology to supply their survival needs, such as hunting and defending possible attacks by other animals. The samples are divided into two groups: archeological and paleontological, and subdivided, respectively, by artifacts and pieces, and fossiles.
In this exhibition, there are fragments of the megafauna animals, such as of the Sloth Giant, such as their jaw (Fig. 1), calcaneus (Fig. 2), lumbar vertebra (Fig.2), axis (Fig. 2), tibia (Fig. 3), talus (foot bone) and caudal vertebra body. In addition, there are other samples of other animals, such as the Giant Armadillo (Gliptodonte), the Armadillo, the Mastodon, the Jaguar, the Artiodactyla, the Notoungulata and the Sabre-toothed tiger.
The ceramic and lithic materials were used to meet the Paleozoic Era human needs. The ceramics that were used, whose samples are in the Museum, are the polished ax, the coconut-breaker (beater) (Fig. 4), the mortar (Fig. 5), and the pestle-hand (Fig. 6). The lithics materials were, for example, the polished ax with workmanship (Fig. 7).
There are also some minerals, such as Calcite Geode (Fig. 8), Rhombohedral Calcite Crystal (the main component of the Lajedo (Fig. 8) and Calcite Geode 'Dente de Cão' (Fig. 8).
