Leading edge technology has uncovered secrets about a world-renowned fossil hoard that could offer vital clues about early life on earth.


Researchers who analysed the 400 million-year-old-cache, found in rural north-east Scotland, say their findings reveal better preservation of the fossils at a molecular level than was previously anticipated.

Fresh scrutiny of the exquisitely preserved treasure trove from Aberdeenshire has enabled scientists to identify the chemical fingerprints of the various organisms within it.

Just as the Rosetta Stone helped Egyptologists translate hieroglyphics, the team hopes these chemical codes can help them decipher more about the identity of the life forms, that other more ambiguous fossils represent.

The spectacular fossil ecosystem near the Aberdeenshire village of Rhynie was discovered in 1912, mineralised and encased by chert -- hard rock composed of silica.Known as the Rhynie chert, it originates from the Early Devonian period -- about 407 million years ago -- and has a significant role to play in scientists understanding of life on earth.
