Microbialites, including biogenic stromatolites, thrombolites and dendrolites, were formed by various microbial mats that trapped and bound sediments or formed the locus of mineral precipitation. Microbialites were common and diverse during the Proterozoic, but declined in abundance and morphological diversity when multicellular life diversified during the Cambrian Radiation. A second decline occurred during the Ordovician Radiation of marine animals, and from then until the present… 
Microbes and mass extinctions: paleoenvironmental distribution of microbialites during times of biotic crisis
TLDR
The case for microbialites behaving as 'disaster forms' in the aftermath of mass extinctions accurately describes the response following the Late Devonian and end-Permian events, and this may be because each is marked by the reduction of reef communities in addition to a suppression of bioturbation related to the development of shallow-water anoxia.
The rise and fall of stromatolites in shallow marine environments
Stromatolites are abundant in shallow marine sediments deposited before the evolution of animals, but in the modern ocean they are restricted to locations where the activity of animals is limited.

TLDR
It is inferred that the end‐Permian mass extinction event decreased the diversity and abundance of metazoans to the point of significantly reducing competition, allowing photosynthesis‐based microbial mats to flourish in shallow water settings and resulting in the formation of widespread microbialites.
Microbial mat controls on infaunal abundance and diversity in modern marine microbialites
TLDR
This work provides support for the theory that certain Precambrian microbialites may have been havens of early complex metazoan life, rather than bereft of metazoans, as has been traditionally envisaged.
A Review on Microbialites: a Korean Perspective
Microbialites are defined as rocks formed by microbial organisms. After their first appearance around 3.5 billion years ago, microbialites occur in various depositional environments throughout
Two episodes of microbial change coupled with Permo/Triassic faunal mass extinction
TLDR
A biomarker stratigraphic record showing episodic microbial changes coupled with a high-resolution record of invertebrate mass extinction across the Permo/Triassic boundary at Meishan in South China is presented.

Resurgence of microbialites and anachronistic facies in the aftermath of Phanerozoic extinction events has hitherto only been documented among the "major five." Based on the classical Silurian
Patterns in Microbialites Throughout Geologic Time: Is the Present Really the Key to the Past?
Microbialites dominated the biosphere throughout the Proterozoic, becoming relatively rarer into the Phanerozoic. Microbialites are potential analogs of life on the early Earth; therefore,

Stromatolites in Precambrian carbonates: evolutionary mileposts or environmental dipsticks?
TLDR
Application of a process-based approach has shown that stromatolites were originally formed largely through in situ precipitation of laminae during Archean and older Proterozoic times, but that younger ProTerozoic strom atolites grew largely through the accretion of carbonate sediments, most likely through the physical process of microbial trapping and binding.
