For those wedded to an evolutionary interpretation of life’s history, the fossil and genetic evidence leave the origin of arthropods a major mystery.
Not much is known about the anatomy, biology, and ecology of the enigmatic trilobozoans.
That the same fossils can be attributed to at least six different phyla of marine invertebrates as well as terrestrial fungi really should give reason to pause.
Last but not least, there is this gem: In 1986 strange mushroom-shaped deep-sea animals were collected offshore South Australia.
John Kimber collected the first fossils of this organism and died tragically at age 38 during an expedition in South Australia in 1964.
