Editing Eocene (section)

=== Arthropods ===

Several rich fossil insect faunas are known from the Eocene, notably the [[Baltic amber]] found mainly along the south coast of the [[Baltic Sea]],<ref>{{cite journal |last1=Wolfe |first1=Alexander P. |last2=Tappert |first2=Ralf |last3=Muehlenbachs |first3=Karlis |last4=Boudreau |first4=Marc |last5=McKellar |first5=Ryan C. |last6=Basinger |first6=James F. |last7=Garrett |first7=Amber |date=1 July 2009 |title=A new proposal concerning the botanical origin of Baltic amber |journal=[[Proceedings of the Royal Society B]] |volume=276 |issue=1972 |pages=3403–3412 |doi=10.1098/rspb.2009.0806 |pmid=19570786 |pmc=2817186 }}</ref> amber from the [[Paris Basin]], France, the [[Fur Formation]], [[Denmark]], and the [[Bembridge Marls]] from the [[Isle of Wight]], England. Insects found in Eocene deposits mostly belong to genera that exist today, though their range has often shifted since the Eocene. For instance the [[Bibionidae|bibionid]] genus ''[[Plecia]]'' is common in fossil faunas from presently temperate areas, but only lives in the tropics and subtropics today.<ref>{{Cite journal |last=Buschman |first=Lawrent L. |date=1976 |title=Invasion of Florida by the "Lovebug" Plecia nearctica (Diptera: Bibionidae) |url=https://www.jstor.org/stable/3493971 |journal=The Florida Entomologist |volume=59 |issue=2 |pages=191–194 |doi=10.2307/3493971 |issn=0015-4040}}</ref> Platypleurin cicadas diversified during the Eocene.<ref>{{Cite journal |last1=Price |first1=Benjamin W. |last2=Marshall |first2=David C. |last3=Barker |first3=Nigel P. |last4=Simon |first4=Chris |last5=Villet |first5=Martin H. |date=29 March 2019 |title=Out of Africa?
