石臼,是一种粮食加工工具,带齿石臼,即臼窝内壁有齿者。石臼在黑龙江省的许多古代遗迹中均有发现,采集的标本也不少。尤其带齿石臼出土的数量渐多,笔者觉得有对其进行考证的必要,因此,本文力求对带齿石臼的年代及产生过程作一点粗浅的探讨。在肇东八里城(金代古城)出土的石臼,外形皆不规整,大小亦不相等,但臼窝径皆在30厘米左右,深20厘米左右,内壁有齿。在与兰西县金代古城女儿城紧邻的女儿屯路旁,曾见一石臼,臼窝上有明显的斜纹臼齿,或许为金代的遗物。1981年,笔者在阿城市的一个村庄里,见到3件带齿石臼,均为花岗岩质,臼体有的较规整,有的不规整,其中一件的平面呈圆角长方形,长50、宽40、高35厘米,臼窝径和深度均为22厘米,窝壁上有斜纹臼齿。1982年7月,在牡丹江市郊五公里遗址北缘的一个水泡子边,发现 Stone mortar, is a food processing tool, with toothed mortar, that is, the inner wall of the mortisee have teeth. Shijiu many ancient sites in Heilongjiang Province have found that there are many specimens collected. In particular, the number of toothed stone mortar unearthed more and more, I think there is a need for its research, therefore, this paper seeks to the toothed mortar age and produce a little superficial discussion. The stone mortar unearthed in Zhaidong Bali Town (Jin Dynasty Ancient City) is irregular in shape and size, but the mortar nest diameter is about 30 centimeters and about 20 centimeters deep, and the inner wall has teeth. Next to the daughter-in-law road next to the daughter city of the ancient city of Jinxi in Lanxi County, there was a stone mortar, obvious diagonal molars on the mortar, perhaps a relic of the Jin Dynasty. In 1981, I saw a group of three toothed stone mortars in a village in the city of Ah, all of them granite. The mortar was more regular and some irregular. One of them was a rectangle with a rounded corner and a length of 50, Width 40, height 35 cm, acetabular fossa diameter and depth are 22 cm, nest wall with molars molars. In July 1982, it was discovered on the side of a blister on the northern edge of the five-kilometer ruins in the suburbs of Mudanjiang
