世所共知，在那四磅重的陨石内部有微小的条形物质，可能是极原始的细菌化石。

Furthermore , as all the world could see , within that four-pound rock from Mars were microscopic rodlike objects that seemed to be the fossilized remains of extremely simple bacteria .

但是火星上并没有发现生物。1996年美国国家航空及太空总署声称在一块火星陨石中发现了细菌化石，但大家大多并不认同这一发现。

But no life has been found on Mars , and the one claim of fossil bacteria in a Martian meteorite , made by NASA scientists in1996 , has been almost universally rejected .

塔里木盆地塔北隆起轮南46井、英买1、2井奥陶纪石灰岩内含有大量的钙藻化石、蓝细菌以及疑难微体化石。

Abundant calcareous algae and cyanobacteria were found in the Ordovician limestone cores from three wells , LN-46 , Yingmai-1 and Yingmai-2 , in the northern uplift of the Tarim Basin .

海底天然气渗漏系统甲烷氧化细菌特征及其产物-冷泉碳酸盐岩的微观分析表明，冷泉碳酸盐岩保存了大量的以纳米为主的细菌化石。

The microanalyses show that bacteria fossils mostly in nanometer scale were preserved greatly in their byproduct-seep carbonates collected in the gas seeping system in GC 238 , the offshore Louisiana Gulf of Mexico .
