Bitter Springs Group

Bitter Springs Group is a paleontological site in the Amadeus Basin featuring fossilized stromatolites and microscopic organisms within silica-rich rock formations. The layers display a sequence of deposits that document different phases of early marine conditions.

The site formed during the Tonian period millions of years ago and remained largely unknown until systematic scientific study began in the mid-20th century. It has since become a window into some of the planet's earliest forms of life.

This site holds meaning for scientists studying the origins of microbial life on Earth and how simple organisms shaped early environments. Visitors can observe the layers that preserve evidence of these ancient worlds today.

The site lies in a remote location where careful preparation and sturdy equipment are necessary for a safe visit. Visitors should expect harsh weather conditions and follow local guidance to stay protected.

The site comprises three separate geological units, each holding different types of fossil remains within its rocks. These subdivisions help scientists trace how early life developed across long time spans.
