스트로마톨라이트 혹은 스트로마톨리스는 얕은 물에서 미생물, 특히 남세균으로 이루어진 미생물막에 의해 퇴적물 알갱이들이 붙잡혀 고정된 여러 층으로 이루어진 생화학적 부착구조다. 스트로마톨라이트는 35 억년 이전에 만들어진 것도 있어 지구상의 생명체가 남긴 화석 중 가장 오래된 기록을 보여준다. However, in the case of a given stromatolite all three could be true (a created fossil core, an initially created living stromatolite structure, and subsequent post-creation growth). Furthermore, the creation of a “fully functioning entity” would seem, almost by definition to have involved the creation of a fossil core and allowed for post- creation growth. There is no fossil evidence, however, for metazoan grazing or damage on Proterozoic stromatolites.

Free postage. Stromatolites were common in Precambrian time (i.e., more than 542 million years ago). Some of the first forms of life on Earth are recorded in stromatolites present in rocks 3.5 billion years old. Although stromatolites continue to form in certain areas of the world today, they grow in greatest abundance in Shark Bay in western Australia. This is a stromatolite fossil that was collected from the Carawine Dolomite in the Gregory Range of Western Australia.

The most popular color? You guessed it: brown. Proterozoic stromatolite microfossils (preserved by permineralization in silica) include cyanobacteria and possibly some forms of the eukaryote chlorophytes (that is, green algae). One genus of stromatolite very common in the geologic record is Collenia.

Geographically, fossil stromatolites are ubiquitous on  Stromatolites are petrified microbial mats, and show the same structures as living microbial mats (and sometimes even fossilized filaments of microbes). 8 Apr 2014 Stromatolites occur widely in the fossil record of the Precambrian, but are rare today. Very few ancient stromatolites contain fossilized microbes.
