==Fossil record== thumb|upright|left|Fossils of ''Notahomarus'' These lobsters are related to the modern-day lobsters. They lived in warm, shallow seas during the Cenomanian period (93.9–100.5 m.y.a.). Fossils have been found at fossil sites in Hjoula and Mayfouq, Lebanon.<ref>[https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=216152 Paleobiology Database] </ref><ref name=Share>Liliana Póvoas, Pedro Dantas [http://www.sharinghistory.org/database_item.php?id=object;AWE;pt;45;en "Homarus hakelensis Fraas 1878 and clupeomorph fishes"] in "Sharing History", Museum With No Frontiers, 2017. </ref>
