'''''Palaeopagurus''''' is an extinct [genus](/source/genus) of [hermit crab](/source/hermit_crab) from the [Lower Cretaceous](/source/Lower_Cretaceous).

A fossil of the species ''P. vandenengeli'' is notable for having been preserved ''[in situ](/source/In_situ)'' in the shell of an [ammonite](/source/ammonite). Along with a lack of fossils of hermit crabs in [gastropod shell](/source/gastropod_shell)s from before the [Late Cretaceous](/source/Late_Cretaceous), this suggests that ammonite shells may have played a more important role in the early evolution of hermit crabs' characteristic shell-dwelling habits.<ref name=Fraaije /> It contains the following species:<ref name="WoRMS">{{cite WoRMS|last=De Grave|first=Sammy|date=24 November 2023|title=''Palaeopagurus'' Van Straelen, 1925 †|id=1596719|access-date=5 December 2024}}</ref>
