During the early Paleogene, greenhouse gases created warm global climates. These warm climates redistributed the habitat of marine and terrestrial biota globally. Understanding the ecology of biotas under extremely warm climates is important to decipher their behavior in future climate warming. Here we report two new legume fossils ( Bhatia, Srivastava et Mehrotra sp. nov., and Bhatia, Srivastava et Mehrotra sp. nov.) from the late Paleocene sediments of Tura Formation of Meghalaya, northeast India. Globally, the Paleocene legume fossil records indicate that legumes most likely immigrated to India from Africa via the Ladakh-Kohistan Arc during the early Paleogene. Moreover, previously reconstructed climate data from the Tura Formation indicate that legumes were well adapted to a warm seasonal climate with monsoon rains.
在古近纪早期，温室气体造就了全球温暖的气候。这些温暖的气候在全球范围内重新分配了海洋和陆地生物群的栖息地。了解极端温暖气候下生物群的生态对于解读它们在未来气候变暖中的行为至关重要。在此，我们报告了来自印度东北部梅加拉亚邦图拉组晚古新世沉积物中的两种新豆科植物化石（巴蒂亚、斯里瓦斯塔瓦和梅赫罗特拉新种，以及巴蒂亚、斯里瓦斯塔瓦和梅赫罗特拉新种）。在全球范围内，古新世豆科植物化石记录表明，豆科植物很可能在古近纪早期从非洲经拉达克-科希斯坦弧迁移到印度。此外，先前从图拉组重建的气候数据表明，豆科植物非常适应温暖的季节性季风气候。
