Eozoon canadense
Eozoon canadense or the dawn animal ("eos" in ancient Greek the dawn and "zoon" the animal) is a well-known pseudofossil that the Canadian geologist and paleontologist John William Dawson believed to have discovered in 1865 as a real fossil.
The assigned name "Eozoon" should indicate that according to the then state of scientific knowledge it was the oldest and most original organic being, with whom the dawn of organic creation, as it were, had dawned. Dawson had found this "organic structure" in Precambrian limestone formations near Grenville-sur-la-Rouge in Quebec . He traced this supposedly organic formation back to a shell-forming organic being from the group of root pods . Very similar shapes were later found in corresponding rock formations in Bohemia and Bavaria . From 1894 strong rock metamorphoses could be detected in the rock formations in Quebec . The formation of this formation could be physically demonstrated as non-organic through very high temperatures and specific chemical processes.
