The discovery of a Middle Pleistocene hominid clavicle is reported here. This discovery is particularly important because clavicles are hitherto unrepresented in the fossil record of Asia. The Narmada clavicle comes from the Boulder Conglomerate horizon at Hathnora near Hoshangabad in the Central Narmada Valley. This is the same deposit that previously yielded the Homo erectus/archaic Homo sapiens partial cranium, which has recently been dated to between 0.2 and 0.7 ma (million years ago). The specimen has some unusual morphology and is a very short and robust bone, far shorter than even the early African Homo erectus clavicles. It is about the size that would be expected in an adult human pygmy. This discovery reopens the debate on the taxonomic position of the Narmada hominid in human ancestry.
本文报道了中更新世人类锁骨的发现。这一发现尤为重要,因为迄今为止亚洲化石记录中尚无锁骨的代表。讷尔默达河锁骨来自讷尔默达河中游谷地霍尚加巴德附近哈斯诺拉的砾石层。此前从该沉积层中出土了直立人/早期智人的部分颅骨,最近测定其年代在20万至70万年前。该标本具有一些不同寻常的形态,是一块非常短且粗壮的骨头,甚至比早期非洲直立人的锁骨还要短得多。其大小与成年人类侏儒的预期尺寸相近。这一发现重新开启了关于讷尔默达河人类在人类谱系中分类地位的争论。
