Transverse section of fossil wood showing files of polygonal to rounded conducting cells and 5 rays (the brown vertical "lines")
#FossilFriday reminder that there are very old fossil #plants with very well preserved cellular detail!
This is a piece of wood from a tree that grew ~340 million years ago (early Carboniferous) in what is now France, prepared as thin-section & seen under the microscope 🔬 🌿⛏️ #paleobotany #botany
Happy #FossilFriday!
Today, we are traveling to the earliest known Neotropical rainforests from the Bogotá Formation (#Eocene), #Colombia
👀 See the tiny holes along the margin of the leaf?
Those are chewing marks made by insect herbivores feasting on this tasty leaf 🐛🤤

#Paleobotany For this #Fossilfriday, a preview of my research on 3D sandstone casts of lycopsids from Belgium’s Uppermost Famennian, using laser scanning at #eddylab, usually applied for vertebrates. Illustration by Stephen Greb.

#Paleobotany This #FossilFriday is dedicated to the Famennian fern-like plant Rhacophyton, a striking example of how reconstructing whole plants from fragmentary individuals remains challenging, even with thousands of specimens. Unraveling its architecture is also at the heart of my ongoing research
M. Krings, C. Harper & I are organizing a symposium for early career researchers:
-👤students to 2 years post PhD
-🌿 any #paleobotany or #palynology subject
- 💶 awards for the 3 best talks
We hope to gather a diversity of subjects & presenters. Don't hesitate to contact me if you have questions!
📣📣 The 12th European Paleobotany and Palynology Congress will take place September 20-24 in Münster 🇩🇪 🌿⛏️ Abstract submission will be opened from mid-April to May 31. All the information is now online here: www.uni-muenster.de/GeoPalaeonto...

A scientific poster about a collection from an understudied lagerstätte framed by stylized art of some of its flora like an illuminated manuscript.
Related to this morning's musings, this is the last scientific poster I ever did. It was an attempt to get the word out about an amazing collection that someone else needed to study because I was leaving the field.

View of Carapace Nunatak from an helicopter. It is an isolated mountain peak rising above the polar icesheet
View of a fossil branch in the field and of a thin-section showing growth rings in the wood
Sometimes you go really far to find fossils that are way too young for your taste and partly rotten...but still very interesting! Here's one example, an early Jurassic conifer branch from Carapace Nunatak, Antarctica 🌲⛏️🇦🇶. Happy #FossilFriday! #paleobotany

A cat lying down in his nice little cat tower next to a table with an opened publication with fossil plant photos, a pen, and a computer. A minute later, the cat will slap his human's arm one more time and throw the pen away to get her to move.
This is my catsistant. He finds #paleobotany utterly boring. His job for the last 15 years has been to slap me while I write to encourage me to go do something else!

This fossil was shown to me and I really liked the delicate fan-like pattern.
Not sure what it is though — maybe a marine plant, or possibly a bryozoan colony.
The texture looks like a net or a leaf, and it made me stop and look twice.

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
Pterocoma pennata, a comatulid ("feather star") from the Jurassic of Germany
Ginkgoites huttoni, a ginkgo from the Jurassic of England.
Cymatophlebia longialata, a dragonfly from the Jurassic of Germany
Pterodactylus antiquus, a pterosaur from the Jurassic of Germany.
Look at all these beautiful flattened Jurassic friends! ⛏️🤓 All from the Paläontologisches Museum München public exhibit -names in alt-text #fossil #paleontology #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
Gorgeously preserved stalks of horsetail criss-crossing over one another on a rock slab on display behind glass
A well-preserved conifer branches ending with circular cones at the end of those branches on the right. The stone slab is sepia-colored; the branches are a darker reddish-brown.

🔬 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.
