It is remarkable, indeed, how detailed a medusoid morphology was projected onto Kimberella fossils and later recognized as pure fantasy.
One of the few features that are uncontroversial is the body size: The fossils measure usually 1-5 cm in length.
The fossilization of Kimberella specimens was most likely based on rapid burial with sand during storm events.
Based on the same fossil evidence, there is obviously much room for speculation and quite different opinions.
The first principle is helping participants discover the evidence for design themselves.
