Abstract: The preliminary study of 6 bone tools and 8 antler spades which were discovered from the rock shelter site locally called Maomaodong, in Xingyi county, Guizhou province is reported in this paper. The bone tools are made of the bone splinters of what part and what animal it belong are now impossible to determine. All of the antler spades are made of the fragments of chopped antlers.
Main type of the bone tools is the awl. They are 5 specimens and are various in shape. According to the shape of the pointed part we have one acute, one flat, one blunt and two oblique pointed awls. Only one bone knife was found in site.
Based on visible evidence of the bone tools, we may tentatively reconstruct the process of the manufacturing of these instruments as follows: First, the animal bone such as a limb bone is struck and then some larger ' and thicker bone fragments are ?selected among the broken bones ； second, they are made into semifinished products of the awls by chipping and scraping; lastly, they are finished into awls with various shape of pointed part by polished on a block of sandstone. Except 6 spades which are scrapered on one surface, all of the specimens are bifacially made by scraping and grinding. The working process of the antler spades is similar to that of the bone tools.
From the point of view of typology these bone tools and antler spades have not been found in the late palaeolithic assemblages in China before. They reveal that ancient men lived in Maomaodong had arrived at a new level in the technique of making the bone tools and stone tools of well trimmed and having regular shape etc. we suggest that it seems to be later in age than all of the palaeolithic industries in China, therefore, it is tentatively dated as the final stage of the palaeolithic age.
