Abstract

The Late Miocene hominid-bearing locality in Haritalyangar, India, has yielded remains of fossil lizards and snakes. The material consists of the following taxa: Varanus and an indeterminate anguimorph, Python, a colubrid and a natricid. These squamates are documented from this region for the first time. A co-existence of Varanus and Python, two iconic squamates, is demonstrated. The overall fauna, which is dominated by both large and small semi-aquatic and terrestrial taxa, indicates seasonally wet sub-humid to semi-arid climate in the area during the Late Miocene, ∼9.1 Ma. Moreover, the mean annual temperature must have been high in the region at that time (not less than 15–18.6 °C, similar to the mean annual temperature in this area today), indicated by the occurrence of important thermophilic elements such as Varanus and Python.

印度Haritalyangar晚中新世人科地区的蜥蜴和蛇化石(Diapsida, Squamata)

在印度Haritalyangar的中新世晚期人类居住地，发现了蜥蜴和蛇的化石遗骸。该材料由以下分类群组成:Varanus和一种不确定的anguimorph, Python，一种杂交和一种钠酸盐。这些鳞片属首次在该地区发现。瓦拉纳斯和蟒蛇共存，两个标志性的鳞片，被证明。整体区系以大型和小型半水生和陆生类群为主，表明该地区晚中新世(~ 9.1 Ma)为季节性湿润半湿润至半干旱气候。此外，该地区当时的年平均温度一定很高(不低于15-18.6°C，与今天该地区的年平均温度相似)，重要的嗜热元素如Varanus和Python的出现表明了这一点。

期刊介绍： Geobios publishes bimonthly in English original peer-reviewed articles of international interest in any area of paleontology, paleobiology, paleoecology, paleobiogeography, (bio)stratigraphy and biogeochemistry. All taxonomic groups are treated, including microfossils, invertebrates, plants, vertebrates and ichnofossils. Geobios welcomes descriptive papers based on original material (e.g. large Systematic Paleontology works), as well as more analytically and/or methodologically oriented papers, provided they offer strong and significant biochronological/biostratigraphical, paleobiogeographical, paleobiological and/or phylogenetic new insights and perspectices. A high priority level is given to synchronic and/or diachronic studies based on multi- or inter-disciplinary approaches mixing various fields of Earth and Life Sciences. Works based on extant data are also considered, provided they offer significant insights into geological-time studies.
