Abstract

ABSTRACT In the ‘50s of the XX century, a German expedition lead by Richard Dehm collected a large amount of fossil remains from northern Pakistan. Among these was an isolated trunk vertebra of a lizard, which is here referred to Varanus sp. The collecting site of this specimen is not precisely known, but it most likely comes from middle to early late Miocene Siwalik sediments of the Chinji Formation. This is the first published record of a fossil lizard from the Neogene of Pakistan and adds to the very patchy record of Varanus Merrem, 1820 in Asia. It further supports previous reconstructions of a warm climate for the middle to early late Miocene of the Siwaliks.

1820年巴基斯坦中新世Siwaliks地区Varanus Merrem的首个化石(鳞片目:Varanidae)

20世纪50年代，理查德·德姆率领的一支德国探险队在巴基斯坦北部收集了大量化石遗骸。在这些化石中，有一个孤立的蜥蜴躯干椎骨，这里称之为Varanus sp.。该标本的采集地点尚不清楚，但很可能来自中新世中晚期的Chinji组Siwalik沉积物。这是首次公布的来自巴基斯坦新近纪的蜥蜴化石记录，并为1820年亚洲瓦拉纳斯·梅里姆(Varanus Merrem)的非常不完整的记录增添了新的内容。它进一步支持了先前关于中新世中期到晚中新世早期的温暖气候的重建。
