古生物学家从地层中寻找生物进化过程中残留的遗骸、遗物与遗迹。骨骼属于遗骸,蛋化石、粪化石属于遗物,脚印属于遗迹。在这些化石中最难发现的就是粪化石。1982年春,北京自然博物馆古生物采集队在云南禄丰采到了大批的恐龙化石,还采到了稀有的鱼粪化石十枚,其中有四枚较完整,最大的一枚宽径达38毫米,长径43毫米。粪化石的发现引起人们的极大兴趣。但是在过去相当长的一段时间里,粪化石并内没有引起人们的注意,因为它们很容易与土壤混合而在自然状态下分解。1827年,英国科学家威廉。巴克
Paleontologists search the strata for the remains, relics and relics that remain during the evolution of the organism. Bones belong to the remains, egg fossils, fecal fossils belong to the relics, footprints are relics. The most difficult to find in these fossils is fecal fossils. The spring of 1982, the Beijing Museum of Natural History paleontology collection team in Luofeng, Yunnan Province, a large number of dinosaur fossils have been collected, but also adopted a rare fish fossil fossils, of which there are four more complete, the largest one 38 mm wide and long diameter 43 Mm. The discovery of dung fossils aroused great interest. However, in the past a long period of time, fecal fossils have not attracted much attention because of their ease of mixing with soil and decomposition in their natural state.
