Fossils range from the Late Cretaceous to the Early Oligocene (99.6mya)-28.4mya). Older fossils (as recent as 70.6mya) occur in Alberta and Saskatchewan, Canada, and the late "Palaeorhynchus zitteli" occurs in Romania [http://paleodb.org/cgi-bin/bridge.pl?action=checkTaxonInfo&taxon_no=35637&is_real_user=1] .
