== Fossil history == thumb|left thumb|upright|right|Top view Allopleuron lived from the Late Cretaceous (Cenomanian age, 94.3 Ma) to the Oligocene (Rupelian age, 28.4 Ma), therefore surviving the Cretaceous-Paleogene extinction event. Fossils have been found from Germany, the Netherlands, Kazakhstan and the United States.
