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.
There is a strange fact that shows that any interpretation of these trace fossils has to be taken with a grain of salt.
Based on the same fossil evidence, there is obviously much room for speculation and quite different opinions.
John Kimber collected the first fossils of this organism and died tragically at age 38 during an expedition in South Australia in 1964.
