Silurian Period
Distribution of landmasses, mountainous regions, shallow seas, and deep ocean basins during the middle part of the Silurian Period. Included in the paleogeographic reconstruction are the locations of the interval's subduction zones.
During the Silurian Period, different endemic groups of fishes developed across three primary regions:
- Laurentia: Fossils have been found in the Canadian Arctic, the Yukon, Pennsylvania, New York, and notably in Scotland.12
- Baltica: Significant findings have been identified in Norway and Estonia.12
- Siberia: Groups have been discovered in this region, including adjacent areas in Mongolia.12
These fishes were widely distributed in marine environments within a broad belt spanning 40° N and 40° S of the paleoequator.1
