None of the Cambrian animal phyla is represented in the Ediacaran fossil record.
The fossil record speaks clearly and cries out loud: the history of life on Earth is a history of saltations.
One researchers has preferred to classify Kimberella among the Ediacaran “fossil problematica.”
It is remarkable, indeed, how detailed a medusoid morphology was projected onto Kimberella fossils and later recognized as pure fantasy.
There is a strange fact that shows that any interpretation of these trace fossils has to be taken with a grain of salt.
