The Enigmatic Tribrachidium and Trilobozoa
Trilobozoans are unique to the Ediacaran biota; they appeared suddenly 560 million-years-ago in the fossil record without any precursors.
Ediacarans Are Not Animals
Even Evans et al. (2021) themselves admitt that “phylogenetic affinities for most of the Ediacara Biota remain enigmatic.”
A Precambrian House of Cards
Wow, that’s cool, they not only found the elusive Ediacaran animals but even could unravel their genomes!?
Namacalathus Revisited — Not Much to See
The new evidence is very ambiguous and totally inconclusive. No far-reaching conclusions should be drawn from such dubious material.
Resurrecting Namacalathus as an Ediacaran Animal
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.
