Eozoon canadense

（重定向自Eozoon）

Eozoön canadense from the Precambrian of Canada, a metamorphic rock made of interlayered calcite and serpentine. Scale in mm.

Eozoön canadense (literally, "dawn animal of Canada") is a pseudofossil.

John William Dawson (1865) described the banded structures of coarsely crystalline calcite and serpentine as a gigantic Foraminifera, making it the oldest known fossil. It was found in Precambrian metamorphosed limestone of Canada, at Côte St. Pierre near Grenville (Quebec) in 1863. It was later found in several other localities. Dawson called it "one of the brightest gems in the scientific crown of the Geological Survey of Canada". In 1894, it was shown that the place where it was found was associated with metamorphism (O'Brien, 1970; Adelman, 2007).
