All of the 15 sculpted representations from Grimaldi appear anthropomorphic. The overall inventory with sexual/reproductive.
Specimen Sex Status

Attribution shows an obvious predominance of pregnant women among complete figurines (Table 2). Three of the 15 have two faces sharing the same body. In two cases these are human heads back to back, while a third juxtaposes a human head with that of an animal. The three cases of two-faced figurines is, so far as I am aware, unique to Grimaldi. It is also worth noting that the several cases of blank visages are very explicit; that is, faces are not simply absent, empty faces are very carefully constructed.
