It conveys the categorical confusion characteristic of the Anthropocene; the once clearly demarcated differences among rocks, life, and humans are dissolving. The image sets news from the frontiers of geology against a teal background, in front of which float conglomerated crystal-like forms.
  
  The backdrop texts recast geologic history as mineral evolution, which studies the intertwined co-evolution of geosphere and biosphere.[i] At top, a possible discovery of primeval fossils shows how "life begets rock, rocks beget life."[ii] Skeptics classify them as "dubiofossils," structures in rock that resemble fossils but may not be biogenic in origin.[iii]  At bottom, evidence of the Anthropocene is found in 'human-mediated minerals,' new kinds of crystals found in mines, shipwrecks, and museum storage.[iv]
  
  The enigmatic amalgamated geophysical chunks are composed of three mineralogical materials cited in the news reports (Hematite tubes, Fiedlerite (formed by slag meeting seawater), Simonkolleite (formed by weathering of zinc-bearing slag)), attached to a piece of Fordite, or Motor Agate (built up layers of enamel auto paint slag, cut and polished).
