These deposits were formed as microbial mats in a subtidal to intertidal environment of a shallow platform system, associated to planar-laminated stromatolites
(Calvet et al.
About a billion years before the dinosaurs became extinct, stromatolites
roamed the Earth until they mysteriously disappeared.
It's one thing to read a description of a stromatolite
and it's another to see a beach edged with them.
The method used in the study consisted of replicating the algorithm proposed by Petrisor and Decho for the study of the orientation of cyanobacteria in marine stromatolites
(Petrisor and Decho, 2006).
Recently, McNamara and Awramik (1992 ) have concluded, from the study of stromatolite
, that at about 700 m.
are large features--often many meters in size--that can be formed by the lithification of laminated microbial mats, (Fig.
Two of the best known dynamic coastal bacterial communities are sebkha and stromatolite

reef from the Early Archaean era of Australia.
The remarkable stromatolite
preservation observed in different sedimentary sections allows for the recognition of macro and microfeatures, as well as the reconstruction of growth fabrics, laminae variations, the exceptional preservation of microbial communities including rod-like bacteria.
Matthew described them as Archaeozoon acadiense, the first Precambrian stromatolite
properly identified in the scientific literature (Matthew 1890; Hofmann 1974; Miller 2003).
