Abstract The Ediacaran frond Charnia , known mainly from fragmentary leaf-like fronds from around the world, is represented by completely preserved specimens with holdfasts in ... Mistaken Point biota of Newfoundland. Previous reconstructions of Charnia from two-dimensional impressions were significantly oversimplified, resulting ... landmark and traditional morphometric analyses of numerous complete Charnia specimens can the preservational biases be removed. Charnia is reinterpreted here as having a series of ...

In this paper, we report two species of the rangeomorph genus Charnia , including the type species Charnia masoni Ford, 1958 emend. and Charnia gracilis new species, from the Shibantan biota. Most of the Shibantan Charnia specimens preserve only the petalodium, with a few ... and stem.
