Description
Distribution
Fossils of this marine species were found in Eocene strata in Île-de-France, France.
gollark: The integer mod 3 type is far superior to the rational type.
gollark: Overflow is wrong. It is truncation.
gollark: *But* adding and multiplying can *sometimes* cause important data to be truncated.
gollark: Assuming deterministic decimal to float conversion the error of that is cancelled out when subtraction at the end occurs.
gollark: `0.2 + 0.2 - 0.2` comes out fine.
