Abstract: Abstract The Rhynie chert provides sublime fossils of cyanobacteria from an Early Devonian hot spring ecosystem. However, only a small fraction of the diversity has been documented. Rhyniotaxillus devonicus nov. gen. et sp., a minute… read more here.

Abstract: Abstract The Rhynie chert (Aberdeenshire, Scotland, UK) plant Horneophyton lignieri is likely one of the most studied elements of Lower Devonian floras considering both macro and microremains. Intriguingly, while larger plant fragments are exceptionally fossilized,… read more here.

Abstract: BACKGROUND AND AIMS Structurally preserved arbuscular mycorrhizas from the Lower Devonian Rhynie chert represent core fossil evidence of the evolutionary history of mycorrhizal systems. Moreover, Rhynie chert fossils of glomeromycotan propagules suggest that this lineage… read more here.

DOI: 10.3390/min13050595
Abstract: Rare earth element (REE) fluorocarbonate mineralization occurs in lacustrine shales in the Lower Devonian Rhynie chert, Aberdeenshire, UK, preserved by hot spring silicification. Mineralization follows a combination of first-cycle erosion of granite to yield detrital… read more here.
