Late Ediacaran strata from Newfoundland, Canada (~574–560 Ma) document near-census palaeocommunities of some of the earliest metazoans. Such preservation enables reproductive strategies to be inferred from the spatial distribution of populations of fossilised benthic organisms, previously revealing...

We calculate probabilistic models of point maps of 13 fossil-bearing bedding surfaces, and show that four surfaces contain conga lines that are not the result of chance alignments.
