A portrait page with a full restored branch onto the left. It has 6 palm like leaves at the end of one branch, hiding a cone, with a second mature cone below it. On the top right is a male floral organ, which is start shaped, and in the bottom right is a cut-way of the female cone showing its development.
I have another #paleobotany restoration guide for this #FossilFriday. This time, it's Kimuriella densifolia, a whole plant bennettitalean from the Late #Jurassic of Japan.
This plant is composed of three organ taxa: Williamsonia, Zamites, and Weltrichia.

Polished section of a fossil fern showing the internal structure of the trunk. There is a thick mantle of small roots (R) surrounding the trunk. The vascular tissues of several leaf bases are visible. Paläontologisches Museum München public exhibit.
Of course the best fossils are always ✨Paleozoic plants✨ This is a polished section of a Psaronius tree fern from the early Permian (~290 million years) of the Czech Republic 🌿⛏️ We can see the root mantle (R) and the base of several leaves (arrows). Happy #FossilFriday & #FernFriday! #paleobotany

The paper refers to this as a "leafy shoot impression" of Cupressinocladus sp.
The paper refers to this as a "putative reproductive structure." It looks like a very bumpy type of pine cone in rock. It has a large dark section with rust-colors and light yellows in others.

The whole slice of fossil trunk. It's about 1.8 meters in diameter - taller than me. (There's also part of a fossil palm tree trunk on the right)
Close up of the fossil trunk showing the center on the left and the growth rings (there are ~250 rings in total)
I'm at the Paläontologisches Museum München this week, working on some long-overdue projects 🙃 They have cool #fossils in the exhibit hall but this is my favorite: a giant slice from the trunk of a redwood #tree (Sequoia sp. ) that was growing in the US ~16 million years ago. 🌲⛏️ #paleobotany

🔬 Takeaway: The evolution of vascular systems in early seed plants was far more complex than previously thought, involving multiple adaptive modifications and transitional stages. Ancient plant evolution was anything but simple. 🌱 (9/9)

Background image represents the so called "star-rings", vascular bundles in the pith transporting water to the apex and the leaf primordia. Within the parenchymatous tissues surrounding them, there are also the mucilage cavities (white globular areas).

A landscape page with a pale green background and two illustrations of Ginkgo on it. On the left is an inaccurate one with leaves coming directly from a branch. On the right is an accurate one with clusters extending from short shoots.
I, too, would like to have a go at the new Spinosaurus soon, but in the meantime:
Here's a slide from my recent talk, which covers the DOs and DON'Ts of restoring ginkgoes within palaeoart!
Enjoy! #Ginkgo #FossilFriday #paleobotany #paleoart #SciComm

From paper: Late Triassic leaf-mine fossil on Cladophlebis denticulata of the Momonoki Formation, Yamaguchi, Japan. (A) Specimen (MMHF11-00001a), on which mines on pinnules and chewing marks are marked with white arrowheads and yellow asterisks, respectively, and (B) its counterpart (MMHF11-00001b), at approximately the same scale. (C) Enlargement of pinna with three mines; orange arrowheads signify putative starting point (i.e., oviposition site) of leaf-mines; however, the starting point of the mine on the right is unseen. (D) Enlargement of two pinnules shows the transition of the frass trail, suggesting larval development while mining, and (E) its counterpart at the same scale. Arrowheads in orange and blue denote an oviposition site (os) and possible pupal chamber (pc), respectively.

From paper: Co-occurrence of endophytic oviposition and Asteronomus maeandriformis in Autunia conferta. (a) Mass occurrence of oviposition scars, which likely housed unhatched eggs (NHMS Ap 37/5). (b) Sketch of (a) showing the distribution of the oviposition scars on the pinnule. (c–e) Oviposition scars with ovipositor slits (arrows) (NHMS Ap 37/5). (f) Oviposition and leaf mining on small Autunia conferta pinnules (MB.Pb.1979/0012). (g) Enlargement of the area in (f). Note the callus tissue surrounding the oviposition sites. (h) Leaf mines and oviposition scars on Autunia conferta (MB.Pb.1979/0014). (i) Irregularly distributed oviposition scars on Autunia conferta (MB.Pb.1979/0020).
From paper: Thin sections of Asteronomus maeandriformis in Autunia conferta from Crock, Thuringian Forest Basin, Germany. (a) Section through an Autunia conferta leaf (MB.Pb.1979/0188) with frass trail (box). The scrolled margins indicate the upper side of the pinnule. (b) Section through the frass trail in (a). Note the upper epidermis (arrow), which covers the tunnel. (c) Another example of a compressed tunnel in the upper parenchyma covered by the upper epidermis (arrow) (MB.Pb.1979/0179). (d) Transverse and longitudinal sections through endophytic frass trails in Autunia conferta (MB.Pb.1979/0188). (e, f) Longitudinal section through a frass trail (MB.Pb.1979/0069). Note the calcite-filled cracks and the thin calcite cover on the upper side of the leaves from shrinkage of the organic matter in (arrows in f).

small red vaguely bell-shaped flowers with translucent fused sepals of the species Florissantia quilchenensis face downwards towards the camera, the branch they're growing from is seen to the right while the leaves of the branch are behind the flowers. behind in the background is a blurry branch showing more flowers and leaves Florissantia quilchenensis is a species of Eocene, Canadian malvacean (mallow family) bisexual reproductive organ who's growth-form and whole-plant appearance is unknown. here I have reconstructed it as a tree similar to other plants in the subfamily Sterculioideae, of which it is nested in. it had an androgynophore with five petals fused into a corolla in alternation with the calyx, the style was longer than the stamens, there were five stamens that bifricated at their tips into two anthers giving it a total of ten anthers per flower, as mentioned previously the sepals of this plant were fused into the distinctive bell-shaped cup
at night after a brief shower of rain, an artificial light illuminates the branches of a tree showing very small pink flowers of the genus Lovellea, small blobs of water cling to the waxy cutiles of the leaves, another two blurry branches (though, without flowers) can be seen in the background Lovellea is a kind of small and basal laurale reproductive organ who's growth-form and whole-plant appearance is unknown. Here i have reconstructed it after a more basal condition with a singular flower to each leaf growing from the axillary bud. the flower was shaped like a radially symmetrical pear with an opening at the top in which small pollinators could crawl in for pollination, the ovaries surrounded by a thick layer of overlapping tepals
a kritosaurin hadrosaur has plucked a branch off of a legume tree that's growing fruit of the species Leguminocarpum olmensis, the branches themselves are partially in fruit and partially in flower still kritosaurin hadrosaurs are a group of "duck billed" dinosaurs from Mexico with tall robust nasals but no nasal crests like those found in saurolophines Leguminocarpum olmensis is a species of Late Cretaceous, Mexican fabacean (bean family) fruit of uncertain taxonomic affinities to other fabaceans, and who's growth-form and whole-plant appearance is unknown. here i have reconstructed it as a cercidoidean with racemose infloresence and alternate distichous bilobed leaves
tri-paired three follicles in the genus Sagaria are seen growing on a plant with two pink flowers below them, each internode grows from a three-lobed leaf's axillary bud. trichomes coat the entire plant, catching drops of water, a soft orange light glows behind the plant Sagaria is a genus of Albian, Italian ranunculacean (buttercup family) fruit who's growth-form and whole-plant appearance is unknown. here i have reconstructed its flowers as closer to buttercups with six overlapping petals forming a cup-like shape and many anthers in its centre. follicles are a kind of fruit that splits down a central seam when ripe to release its seeds
this week's #Paleostream was a Valentine's Day special where we drew fossil angiosperms! this week we drew Florissantia (i drew F. quilchenensis), Lovellea, Leguminocarpum olmensis, and Sagaria #paleobotany #palaeobotany #paleoart #botany #sciart

An impression of a fossil leaf showing details of the veination. The apical and lower parts of the leaf are missing
A piece of Glossopteris leaf from the late Permian of Antarctica ~260 million years old 🌳⛏️. Broken but showing nice detail of the veination. Glossopterids are seed plants that were found on all of today's southern continents during the Permian. Happy #FossilFriday! #paleobotany #botany

Fossil wood broken in longitudinal view shiwing the elongated conducting cells. They are a bit smaller in diameter than the hair on the right side of the photo.
Reposting this old photo for #FossilFriday: what you are looking at is a fragment of Callixylon wood from the Late Devonian, about 360 million years ago, seen under the microscope. The elongated structures are the conducting cells & there's a hair on the right for scale. 🔬🌿⛏️

New arrival to the collection—early angiosperm flower in Cretaceous amber (~100 Ma). Morphology consistent with *Eophylica priscastellata* or a related basal flowering plant. Amber preserved this rare specimen of one of the first flowers on Earth. #paleobotany #amber #fossils #cretaceous

New synthesis shows Italians exploited olive trees for 6,000+ years and produced oil 4,000 years ago, far earlier than once thought. Evidence challenges colonial narratives. #Archaeology #AncientHistory #RomanItaly #Paleobotany #Archaeobotany www.anthropology.net/p/the-italia...

Detail of the wood tissue in a fossil stem of Sigillaria seen under the microscope. It shows files of conducting cells and rays.
Today's lycopsids ("clubmosses") are small plants and do not produce wood but some of their Paleozoic relatives did! This is a detail of the wood cells in a stem of Sigillaria from the Carboniferous of the USA 🔬🌿⛏️ Happy #FossilFriday!
