[[Ginkgoales]], of which the sole living species is ''[[Ginkgo biloba]]'', were more diverse during the Jurassic: they were among the most important components of Eurasian Jurassic floras and were adapted to a wide variety of climatic conditions.<ref name="Zhou-2009" /> The earliest representatives of the genus ''[[Ginkgo]],'' represented by [[Ovule|ovulate]] and pollen organs similar to those of the modern species, are known from the Middle Jurassic in the Northern Hemisphere.<ref name="Zhou-2009" /> Several other lineages of ginkgoaleans are known from Jurassic rocks, including ''[[Yimaia]]'', ''[[Grenana]]'', ''[[Nagrenia]]'' and [[Karkeniaceae|''Karkenia'']]. These lineages are associated with ''Ginkgo-''like leaves, but are distinguished from living and fossil representatives of ''Ginkgo'' by having differently arranged reproductive structures.<ref name="Zhou-2009">{{Cite journal|last=Zhou|first=Zhi-Yan|date=March 2009|title=An overview of fossil Ginkgoales|url=https://linkinghub.elsevier.com/retrieve/pii/S1871174X0900002X|journal=Palaeoworld|language=en|volume=18|issue=1|pages=1–22|doi=10.1016/j.palwor.2009.01.001|quote=}}</ref><ref>{{Cite journal|last=Nosova|first=Natalya|date=October 2013|title=Revision of the genus Grenana Samylina from the Middle Jurassic of Angren, Uzbekistan|url=https://linkinghub.elsevier.com/retrieve/pii/S0034666713001115|journal=Review of Palaeobotany and Palynology|language=en|volume=197|pages=226–252|doi=10.1016/j.revpalbo.2013.06.005|bibcode=2013RPaPa.197..226N }}</ref> ''[[Umaltolepis]]'' from the Jurassic of Asia has strap-shaped ginkgo-like leaves with highly distinct reproductive structures with similarities to those of peltasperm and corystosperm seed ferns, has been suggested to be a member of Ginkgoales ''sensu lato.<ref name="Dong-2022">{{Cite journal |last1=Dong |first1=Chong |last2=Shi |first2=Gongle |last3=Zhang |first3=Xiaoqing |last4=Wang |first4=Zixi |last5=Wang |first5=Yongdong |date=November 2022 |title=Middle-Late Jurassic fossils from Northeast China confirm the affiliation of Umaltolepis seed-bearing structures and Pseudotorellia leaves |url=https://linkinghub.elsevier.com/retrieve/pii/S0034666722001610 |journal=Review of Palaeobotany and Palynology |language=en |volume=306 |pages=104763 |doi=10.1016/j.revpalbo.2022.104763|bibcode=2022RPaPa.30604763D |s2cid=251917169 }}</ref>''
