The Avalonian Ediacaran fossil assemblage of Newfoundland, Canada contains abundant fossils with a wide range of morphologies and preservational styles. Quantitative morphological and statistical analysis in Ediacaran fossil assemblages has recently been used to recognize natural morphological groupings, providing evidence for variability within and between taxa. This approach is first used herein to test the grouping of the serially arranged, millimeterscale chambered organism known as Palaeopascichnus. The combined morphometric and statistical analytical approach was applied...
