“…Both the extant Keteleeria and Pseudolarix species are adapted to middle‐ to warm‐temperate climate conditions; however, it appears they have adapted to a much wider range of conditions during the Oligocene–Miocene time, as some of them are associated with the cooler temperate forest vegetation. The same is evident in Cunninghamia , where para‐autochthonous assemblage (foliage shoots and seeds) was recorded in cooler temperate Shichiku flora (Yabe & Yamakawa, ). The range of distribution appeared to have shrunk during the Langhian to Messinian, while it became diversified during the Pliocene.…”

“…This species was recorded from various localities of late Oligocene–late Pliocene. Yabe & Yamakawa () re‐examined the holotype of this species with additional specimens from the earliest Miocene Shichiku flora, as well as late‐middle and late Miocene floras in Japan and Korea. Accordingly, it was presumed that several species might have appeared during the Pliocene epoch in central and western Japan.…”

“…The range of distribution appeared to have shrunk during the Langhian to Messinian, while it became diversified during the Pliocene. Appearance of different taxa of Cunninghamia have been suggested by Yabe & Yamakawa () during the late Pliocene. Such speciation was not recorded in Pseudolarix but in Keteleeria during the early‐late Miocene.…”

“…Therefore, the genus also has second peak like in Pseudolarix. If we take Cunninghamia species from the earlymiddle Miocene of south Sakhalin (Fotojanova, 1988;Yabe & Yamakawa, 2017) into consideration, the distribution changes in this genus also follow a similar trend.…”

Temporal and spatial changes of ten conifer genera that are endemic to East Asia were analyzed based on fossil data from humid temperate forests in the Japanese Islands and Korean Peninsula to elucidate the phytogeographic history, and to understand differences between those genera eliminated from the Japanese Islands and those that remained extant. All these genera, except for Thujopsis, have existed in the area since the Paleogene and remained in the Japanese islands after initial separation from the continent at the early–middle Miocene. Fossil representatives of locally extinct six genera have tendencies to adapt to wider ranges of climatic conditions than their modern relatives. Metasequoia, Glyptostrobus, and Taiwania began to change their distributions since the late Miocene possibly through habitat partitioning. Keteleeria, Pseudolarix, and Cunninghamia appeared to have expanded their habitat toward warmer conditions during the mid‐Miocene Climatic Optimum and then became restricted to warmer forest vegetation by the end of Pliocene. Overall changes in their distribution can be explained by climatic effects. On the contrary, three genera endemic to Japan (Sciadopitys, Cryptomeria, and Thujopsis) followed clearly different trends from the others. Cryptomeria and Thujopsis were especially adapted to cooler‐temperate climate and they retained their habitat areas in the northern part of Japan. During the late Miocene–Pliocene, the islands connected with the Eurasian continent again, which probably acted as a corridor for warm‐adapted genera to disperse southwest. Current data suggest that ecological requirements of each genus might be essential to determine whether they could survive on the Japanese Islands.

Conifers of the taxodiaceous grade of Cupressaceae were more diverse and widespread during the Mesozoic than they are today. The earliest diverging subfamily, Cunninghamioideae, only includes a single extant genus, but has at least 10 fossil genera. Here, two additional cunninghamioid genera are characterized on the basis of permineralized seed cones from the Upper Cretaceous of Hokkaido, Japan. These conifers display seed cone characters typical of cunninghamioids; however, they have a mosaic of characters that are not seen in any reported conifer of Cupressaceae. They are, therefore, designated as two new extinct species: Ohanastrobus hokkaidoensis gen. et sp. nov. and Nishidastrobus japonicum gen. et sp. nov. These newly reported conifers expand the taxonomic and morphological diversity of cunninghamioids. The stratigraphic and paleobiogeographic records of cunninghamioids and other fossil Cupressaceae with foliate seed cones indicate they peak in diversity during the Cretaceous. The living genera Taiwania and Cunninghamia appear during the Albian and Campanian, respectively, and maintain a nearly continuous fossil record through to today, while nearly all other extinct genera of Cupressaceae with foliate cones disappear by the close of the Campanian. As more ancient cunninghamioids are recovered, our understanding of macroevolutionary patterns of this once diverse lineage will be further elucidated.
