摘要翻译：
我们报告了2012年12月29日在斯里兰卡中北部省坠落的碳质陨石中首次发现硅藻截锥球。由于结构内的元素丰度与周围基质的元素丰度密切匹配，污染被排除在外。也有证据表明，在形态上类似于红雨细胞的结构可能导致了陨石坠落后几天内的红雨事件。有关硅藻化石的新数据提供了强有力的证据来支持彗星泛精子症的理论。

英文摘要：
We report the discovery for the first time of diatom frustules in a carbonaceous meteorite that fell in the North Central Province of Sri Lanka on 29 December 2012. Contamination is excluded by the circumstance that the elemental abundances within the structures match closely with those of the surrounding matrix. There is also evidence of structures morphologically similar to red rain cells that may have contributed to the episode of red rain that followed within days of the meteorite fall. The new data on fossil diatoms provide strong evidence to support the theory of cometary panspermia.
