Moodies Crinkles Microbial Mats Oldest Land Life

Oldest Terrestrial Life: Moodies Group Fossil Microbial Mats

The Moodies Group fossil microbial mats represent the oldest trace of terrestrial life to date, dating back approximately 3.22 billion years. This remarkable material contains a wide variety of well-preserved sedimentary structures that are easily visible. This specimen offers an important and fantastic window into the land-adapted microbial life from our early Earth.

Moodies Crinkles: A Unique Geological Feature

The "Moodies crinkles" are siliciclastic terrestrial mats from the Dycedale Syncline. They differ from their "cousin," the Saddleback Syncline fossil microbial mats, which were restricted to a shallow aquatic environment. The significant difference between these two fascinating synclines and their microbial mat structures is that they represent a morphological transition from an aquatic to a terrestrial environment.

Evolution from Aquatic to Terrestrial Life

The evolution from an aquatic to a land environment required more structure and morphological change. The microstructures reveal a denser, interwoven mesh containing fine-grained particles mixed with filamentous strands that gripped various biofilm forms. The preserved land-dwelling carbonaceous mats are thicker than mats formed by marine-dwelling microbial life (Saddleback Syncline). The Moodies crinkles were the forerunner ancestors to the stromatolites.
