From: A common arthropod from the Late Ordovician Big Hill Lagerstätte (Michigan) reveals an unexpected ecological diversity within Chasmataspidida

Fig. 15

Geographic distribution of chasmataspidids. Occurrences are shown on paleogeographic reconstructions for the Middle–Late Ordovician, Early–Middle Silurian, and Early–Middle Devonian. Hoplitaspis is indicated by a star while other chasmataspidids are represented by circles. Ba = Baltica, Eu = Euramerica, Go = Gondwana, La = Laurentia, Si = Siberia.
