The excavation concentrated on the zones identified as “area 1” (zone A and zone B) and the north-east cavity of the karstic structure which showed a high density of finds during the survey undertaken the previous year.

A large quantity of skeletal remains was recovered in this area from adult and young examples of Bison priscus (fragments of cranium, vertebrae, ribs, radius-ulna, carpals, metacarpals, coxae, femurs, tarsals). The complex spatial disposition of the bones, which overlay each other in a jumbled manner and were often touching, required a delicate intervention to remove them. The inclination of the longitudinal axis of the zeugopodial, stilopodial and metapodial bones, with respect to the horizontal, varied greatly. Many presented an inclination of circa 30°-35° (femur 08.152, humerus 08.153, radius 08.164), whilst others were in a sub-horizontal (coxae 08.094 and 08.185)or sub-vertical (coxa 08.200) position.

Of particular interest the discovery in the north-east cavity of a calcareous layer 4-5 cm thick that was probably the basal alabastrine crust mentioned by Pasini (1968). According to Pasini the alabastrine crust was situated at the base of the sinkhole.
The distal troclea of femur 08.152 was resting on the calcareous layer and the rib 08.188 was partially incorporated into the limestone above the crust. The spatial position of the finds in the north-east cavity was documented using measurements taken from three fixed points, two of which were already inserted in the plans made during the previous year.

Some remains bore teeth marks left by large predators (probably wolf), whilst on others fractures were visible that were caused when the animals fell into the sinkhole. The extremities of the long bones showed signs of having been gnawed by carnivores.

During the excavation of the sinkhole 220 finds were recovered, 72 of which were cranium and mandible fragments from small rodents and 3 were from birds. A further 86 fossil remains were found in the sieved sediments from the wall area 1b (from n. 08.001v to n. 08.086v), all from rodents (hemimandibles and isolated molars) apart from find n. 08.025v (insect hemimandible), ns. 08.076v and 08.087v (chiropteran hemi-mandibles) and n. 08.018v (reptile teeth).
