Trilobozoans are unique to the Ediacaran biota; they appeared suddenly 560 million-years-ago in the fossil record without any precursors.
Even Evans et al. (2021) themselves admitt that “phylogenetic affinities for most of the Ediacara Biota remain enigmatic.”
Wow, that’s cool, they not only found the elusive Ediacaran animals but even could unravel their genomes!?
The new evidence is very ambiguous and totally inconclusive. No far-reaching conclusions should be drawn from such dubious material.
The new fossils stem from a layer in the Nama Group of Namibia, just below an ash bed that could be radiometrically dated to 547.32 ± 0.65 million years.
