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.
But what about tracks of the moving animal? There are indeed some fossils from the White Sea.
A former teacher of mine was the late Adolf Seilacher, who was a leading authority on trace fossils and who for obvious reasons preferred to be called “Dolf.”
Fossils often leave much room for very different interpretations of relatively poor evidence.
