The peculiarity of this terramara is that its antiquities would appear to belong to both the Stone and Bronze Ages. The flint implements included about 20 roughly-chipped tools like scrapers, some badly-made arrow-points, and saws resembling those found in the palafittes in the Mincio. Altogether 216 worked flints and about 600 chips and cores were collected. Some polished stone axes, together with four portions of perforated implements. Among about 120 spindle-whorls of burnt clay there was only one ornamented. There were various implements of staghorn and bone, a few of the former being perforated and apparently used as axe and hammer heads like those from Gorzano. Some perforated shells are also recorded. The pottery was precisely similar to that usually found on the well-known terramara deposits of Emilia, showing various forms of handles, horn-like projections, perforated knobs, etc. The total number of bronze articles amounted only to seven pieces, and included a small sickle, a coltello-ascia like that from Bosisio (=Fig. 51=, No. 10), and a small dagger with two rivets--the rest being of an undetermined character. Two objects of _pietra ollare_ (a small spindle-whorl and a dish turned on the wheel) and a bronze buckle were found among the disturbed beds on the surface. Beyond the valley of the Po no decided remains of palafittes or terremare have come to light, and the obscure indications that have been recorded leave it doubtful whether they are of a prehistoric character.[41] Of these the only one worthy of detailed notice here is the dwelling found near Offida, in the Piceno district (Central Italy), and described by Professor Pigorini. (B. 343b.) About one and a half miles from Offida, in a small valley surrounded by hills, there was formerly a small lake, which has become drained by the erosion of a stream which falls into the Tresino. Here, covered with 16 feet of sand and _débris_, the Marquis Allevi found a platform 50 yards long, 15 yards wide, and 2 feet thick. Below the platform there was lake-mud, containing fresh-water shells, to the depth of 9½ feet, in which were charcoal, bones of animals, fragments of pottery, and other remains of human occupancy. This platform was constructed of large trunks deprived of their branches and laid horizontally at intervals of about four feet, above which came smaller beams irregularly laid without any order and then a layer of clay and moss. On this platform were found calcined round stones, the bottom of a dish, and some 12 fragments of other vessels, some of fine and some of coarse pottery. One bit had a recurved lip, and another was ornamented with a kind of zig-zag ornamentation in incised lines. There were also about 20 pieces of copper, some of which looked like crucibles.
