1.6 亿年前的巨型蝌蚪化石,是已知最古老的化石,在阿根廷发现。 160-million-year-old giant tadpole fossil, the oldest known, discovered in Argentina.
科学家们已经发现了阿根廷一个巨型的塔德波石最古老的已知化石,估计约1.6亿年,比上一个记录高出2 000万年。 Scientists have uncovered the oldest known fossil of a giant tadpole, estimated to be around 160 million years old, in Argentina, exceeding the previous record by 20 million years. 这块化石保存在砂岩中,包括部分头骨和脊椎骨,特征类似于现代蝌蚪。 The fossil, preserved in sandstone, includes parts of the skull and backbone, and features similar to modern tadpoles. 这一发现增强了对青蛙演变的了解,突出了两栖动物在整个大规模灭绝期间生存战略的稳定。 This discovery enhances understanding of frog evolution and highlights the stability of amphibians' survival strategies throughout mass extinctions. 这一研究结果发表在"自然"杂志上. The findings were published in *Nature*.
