Redlichia fossil map
Where fossils of Redlichia have been found, shown on the Earth as it looked about 500 million years ago and on today’s map.
Dots are fossil collections recorded in the Paleobiology Database. The “then” view moves today’s fossil sites back to their positions 500 million years ago (the time slice nearest the median age of the fossils) using the Merdith et al. (2021) plate model; positions are approximate. Open on the timeline map →

About Redlichia
Redlichia is a genus of redlichiid trilobite in the family Redlichiidae, with large to very large species (up to 35 centimetres or 14 inches long). They are characterised by a flat body plan, prominent genial spines and for some species, a distinguished axial spine. Fossils of various species are found in Lower Cambrian (Toyonian)-aged marine strata from China, Korea, Pakistan, the Himalayas, Iran, Spain, southern Siberia, and Antarctica, and from Middle Cambrian (Ordian)-aged marine strata of Australia.
