AN EARLY HISTORY OF ORISSA
the upper end of the trench one has a convex margin and squarish butt. Crude choppers, but smaller in size than the earlier ones, continued to exist.
Right near the top, a different technique appears in a deeper layer in Kalabaria. These tools seem to have been dressed on one lateral margin by nearly vertical blows, while the block was resting on the other margin upon some hard object serving as an anvil. Under such blows, symmetrically disposed step-fractures developed on or near the margins—the fractures being generally deep and extensive.
Kalabaria
The in-situ tools here begin with a fine worked pearl. form biface. But cruder handaxes continued side by side, for they also appeared several inches higher. Cleaver-like tools with working edge are found here. Discoid tools used as chopper or side-scraper too continued. The method of working on an anvil appears fairly early (No. 46, Kb. 6B-1), but this does not appear to have been a very common process.
Koilisuta
It yielded a very crude heavy boulder trimmed on one margin and was followed by a neat transverse cleaver with pebble butt. Nuaberi
All the tools here are confined to a thin layer of secondary pisolitic laterite at the top of the mound. The earliest was a small guillotine-type of cleaver with U-butt. Close-by lay a neately worked biface, with parallel sides and obtusely pointed anterior, possibly a knife. Then çame another guillotine cleaver with divergent lateral
