Palaeogeographic map of the Eifelian Stage (Middle Devonian) indicating the geographic location of the studied collections of trilobite specimens included in the TriloMorph database (green) and location of collections from the PBDB (pink) in order to show the geographic coverage of TriloMorph. Palaeogeography is reconstructed using the PALEOMAP model115 in GPlates116.
