Charnia is an extinct genus of frond-like lifeforms belonging to the Ediacaran biota with segmented, leaf-like ridges branching alternately to the right and left from a zig-zag medial suture (thus exhibiting glide reflection, or opposite isometry).

2024年1月15日 · Charnia Masoni thrived during the Ediacaran Period, a time frame that spanned from approximately 635 to 541 million years ago. This period is crucial in Earth’s history as it marks the emergence of multicellular organisms, preceding the famous Cambrian Explosion.

Charnia masoni was the first Ediacaran fossil to be recognised as coming from demonstrably Precambrian strata and therefore played a fundamental role in demonstrating that the Ediacaran biota lived prior to the Cambrian Period.

2022年7月25日 · Its major claim to fame is the fossil known as Charnia masoni. This was found in the 1950s by two schoolchildren - Roger Mason and Tina Negus - and was the first ever Pre-Cambrian fossil to...

2018年9月11日 · The Ediacaran macrofossil Charnia masoni Ford is perhaps the most iconic member of the Rangeomorpha: a group of seemingly sessile, frondose organisms that dominates late Ediacaran benthic, deep-marin...

Charnia masoni is an extinct, frond-like organism (rangeomorph) from the Ediacaran period (~560 Mya). It is recognised as one of the first multi-cellular, complex lifeforms to appear on Earth.

Charnia masoni was first described from the Maplewell Group in Charnwood Forest in England and subsequently was found in Ediacara Hills in Australia, Siberia and White Sea area in Russia and Precambrian deposits in Newfoundland, Canada. It lived around 570-550 million years ago.
