| 内容記述 | A fine sample of Stegodon aurorae was discovered by children of the Shiokawa Primary School on May 29th, 1971, at a locality in Shiokawa, Maruko-machi, Chiisagata-gun, Nagano Prefecture. Several fragments collected from a small talus at the foot of a river-side cliff on the River Matsuba were restored and described. Though the sample was collected from the talus, its derivation from the upper part of the Upper Okui Formation exposed just above the spot is undoubted. The sample is a lower jaw broken into right and left halves, each of which with nearly complete M1 and a part of M2. Ml is well worn out, but M2 is not. Moreover, several lamellae obtained separately from the same spot are restored successfully and are found to make up for the lost distal part of the right M2. The principal characteristics of the mollars are as follows. The size of the left M1 is 146mm in length, 63mm in width and 42mm in maximum height; that of the right M1 is 136mm + in length, 64mm in width and 38mm in height; that of the right M2 is 210mm in estimated length, 74mm in width and 59mm in height. The ridge formula is x-8-x in M1 and x-10-x in M2. The ridge frequency is 6. 5 in Ml and 5 in M2. The enamel is about 3mm thick. The ridge is like the chirolite of the true elephant, and the valley is narrowly V-shaped. Three patterns of enamel fold are recognized, that is, two constrictions of both sides which represent the lateral fissure, several plications which correspond with mamillae and small plications which count five to six in 1 cm. | |||||||
