Description It's autumn in the latest Cretaceous somewhere in North America's coastal plains, and the riverside forests are in their best fall colours. A Troodon is inspecting it's territory. The first fall floods have turned the rivers muddy and washed off most of the floating vegetation that covers the surface during summers.

From Late Cretaceous into well in the Eocene there was a distinct community of plants in disturbed sites - such as empty river channels, collapsed riverbanks, and wildfire sites in many parts of the world. The community consisted of some combination of Ginkgoes, katsura trees (Cercidiphyllum), dawn cypress (Metasequoia), sycamore (Platanus), and delta cypress (Glyptostrobus). All of these except for sycamore are shown here, along with aquatic angiosperm Trapago angulata and dipteridaceaen fern Hausmannia and a bunch of other plants.

Unlike the weedy plant communities of today's disturbed areas, all of these trees live to be very, very old. And one thing you don't see often enough in paleoart is that old trees may look pretty weird. Ginkgoes, for example, have a habit of sprouting weird aerial root-like growths called chi chi (which is apparently Japanese for breasts). When they touch the ground, they sprout roots and start acting as a holdfast for new trunks.

Interestingly, while deciduous plants were a minority during the Cretaceous, at least all modern congenerics of the Ginkgo community shed their leaves and have rather flashy autumn colours. It makes me imagine a pterosaur-eye view of monotonically dark green, ancient coniferous forests suddenly splashed with eye-hurtingly bright yellows and reds here and there.

This one has to do with my next Botany of Paleoartists blog posts, coming as soon as I'm less busy with work again. Also, prints available!

"It makes me imagine a pterosaur-eye view of monotonically dark green, ancient coniferous forests suddenly splashed with eye-hurtingly bright yellows and reds here and there." Β  Research sibiria during automn and youll get exactly that. (since its mostly coniferous forest)

Yeah - in Siberia, I think one of the most common conifers is the Siberian larch, which is also decidous and have a golden-yellow autumn colour.

For some reason I have always considered all conifers to be evergreen trees. An exciting research awaits! lol

Remind me to consult you if I ever need to know about the foliage of a certain time and place.

Incredibly inspiring work, both artisticaly and scientificaly. I've always thought the field of paleobotany could be explored more and your art and blog posts really help me picture the environnments of ancient ecosystems.

Your lines are smooth and tender and colors bright. It really helps picture this extinct forest.

I agree that more focus on environments and flora could often make paleoart even more interesting.

Amazing work with all those warm colours! Didn't know ginkgos have such a weird root system. The only trees I've seen so far are the young ones they've planted in our city but I fear those will never be allowed to grow old and big with such weird shapes...

Thanks!

I think even fairly young ginkgoes may grow small chi chis that look more like little bumps on their branches. Perhaps you could keep an eye open for those.

I'm a bit envious for you living in an area with ginkgoes as city trees. In Finland it's slightly too cold for them: there were a couple of small ones in the botanical garden here, but I think some particularly cold winter finished them, as I haven't been able to find them anymore. I have two tiny potted ginkgoes on my balcony, though. They do well as long as I protect them from the coldest weather around January and February.

You're welcome

Allright, when I'm in town I'll see if they have those

Yeah, it's weird though how I actually only noticed them a few months ago while they are planted quite some years back I think. I never payed any attention to it and suddenly I started to see ginkgos everywhere.Β 
Finland seems a bit too cold for them yes, although I think Belgium isn't the best place for them either: sometimes we can have some pretty cold winters too (a few years ago we had temperatures of about -15Β° C at night and that's too cold for those trees right?)

Oh, you're from Belgium. Cool!

Actually, I just read a paper that stated the current distribution of "wild" ginkgoes (it's questionable if the few Chinese semiwild stand are actually natural or just were planted very long ago) is anomalous compared to the climates ginkgo has grown in much of the species lifespan. The authors claim that the ginkgo is adapted to fairly cool temperate climates, with winter temperatures all the way down to -20Β°C. The very last trees just happened to get stranded in the southern end of it's distribution.

I think that the closest big ginkgoes grow in Stockholm, where there is snow and freezing weathers yearly. In Finland, the temperature apparently dips either too much below freezing or for too long at a time, which tends to kill them sooner or later. Personally, I have taken my ginkgoes inside from the balcony when the thermometer hits -10Β°C, which has seemed to work fine.

Yeah, it's a pretty good country to find ginkgos: in some parks you can find them, in the street where I live there's a house with some small ones in the front yard and in our capital there's somewhere a street with big ones planted on both sides

Okay, that's maybe usefull for later: if I have the place I'd like to have one in my yard too (or a small one in pot).

Cool!
Informative too!
Nice Chi Chi's
I really like the aerial rootsΒ  of a Ficus benghalensis - Indian Banyan Tree.
Thanks for sharing

Since we're still on botany, can you help me crack a floral riddle that I've made?

For some time, I've been crafting an alternate Earth which uses plants to determine the climate.Β  The tropics I won't say much, except that they reach to latitudes of 25 degrees.

Temperate--Pine, Oak, Fig, Olive, Palm, Redwood, Araucaria, Hickory, Beech, Ash, Elm, Eucalyptus, Hazel, Orange, Lime, Grape, Banana, Lemon, Pineapple, Mango, Gourd

Arctic--Oak, Pine, Redwood, Araucaria, Fir, Douglas fir, Larch, Cedar, Hemlock, Yew, Maple, Cottonwood, Alder, Rowan, Birch, Apple, Pear, Peach, Apricot, Plum, Gingko

Alpine--Pine, Fir, Spruce, Aspen, Rowan, Gingko, Cherry, Rhododendron



Using this list, what would the climate of each zone be like?
