The cave was first excavated in 1927. The central part and the eastern area of the funerary space were found destroyed, since the cave was used to keep livestock. The cavity, excavated by Serra Vilaró, preserves some of the slabs that would have formed part of the sepulchral structure, although they are not in their original position. About 15 individuals represented by skulls and numerous long bones were documented. Most of these individuals appeared in a secondary position except for one skeleton that preserved anatomical connection. These remains were on a layer of ashes. Likewise, scarce bone remains are observed at the E end of the cave.

The pottery collected allowed the reconstruction of a truncated-cone vessel of hand-made pottery, with a rough exterior surface and a fine interior, with knobs and with esparto impression on the base. It measured 14.7 cm in mouth diameter, 9 cm in base diameter, 14.7 cm in height and 5 cm in thickness. Fragments of lithic and bone industry, and remains of fauna and botany also appeared. Due to the architectural type, the archaeological materials and the funerary ritual, the sepulchral level of the cova de Puiganseric is placed chronologically in the late Neolithic-Chalcolithic-early Bronze Age.
