Abstract
A humerus and two radii of juvenile dwarf hippopotamuses are redescribed. The subfossil bones from the collection of the Museum für Naturkunde Berlin were erroneously assigned to the horned crocodile Voay robustus (Grandidier & Vaillant, 1872) by Bickelmann & Klein (2009). All three limb bones presented here belong to immature animals. The epiphyses are not fused, except the proximal extremity of the right radius; and the radius and ulna are also unfused. The two radii are from individuals of different size, whereas the left radius and the humerus are from animals of similar size. Morphologically, the limb bones cannot be identified to species level. A tentative assignment to Hippopotamus madagascariensis is discussed based on the knowledge of the geographic origin on the island. (© 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
马达加斯加晚更新世矮河马的前肢骨(哺乳纲，鲸足目)，先前被确定属于鳄鱼科
重新描述了幼年矮河马的一个肱骨和两个桡骨。来自柏林自然博物馆收藏的亚化石骨头被错误地认定为有角鳄鱼Voay robustus (granddier &比克尔曼(Bickelmann &克莱恩(2009)。这里展示的三块肢骨都属于未成熟动物。除右桡骨近端外，骨骺未融合;桡骨和尺骨也没有融合。这两个桡骨来自不同大小的个体，而左桡骨和肱骨来自相似大小的动物。在形态学上，肢骨不能被识别到物种水平。根据对该岛地理起源的认识，讨论了马达加斯加河马的初步归属。(©2010 WILEY-VCH Verlag GmbH &KGaA公司，Weinheim)
