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

How many different #lichens on a single #tree? 🌳 I don't know but this is just a selection from the upper branches of a single oak (Quercus robur or petraea) uprooted this week by storm Nils 🌪️🌳 #botany

Asked my Intro Plant Bio students to make Valentine's day plant meme using what they learned in class so far, and dang, it gives me SO MUCH joy seeing all the submissions. Some of my favs here: #valentinesday #ib103 #iamabotanist #plantjoy @botsocamerica.bsky.social l @plantteaching.bsky.social

Nice weather for liverworts 💚☔💚☔💚

The first article from my PhD has just been published in JAES: "Lutetian swamp-freshwater palynoflora from Bultu-Zile (central Anatolia, Türkiye): implications for Eocene ecosystems of Balkanatolia". doi.org/10.1016/j.js... This work has been conducted as part of @dispersal-erc.bsky.social 1/4

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

A stunning work on the anatomy of the apical meristem in Medullosans, showing fascinating similarities with extant cycads! academic.oup.com/aob/advance-...

The seed fossil record of Solanaceae revisited is out! Using morphometrics and micro-CT data from 110 fossils and 354 extant taxa, we described 6 new genera and 6 new species, doubling fossil diversity for the nightshades! 🔗 doi.org/10.1002/tax.... @iochromaland.bsky.social

This is truly baffling. A seed does not become an angiosperm fruit only because there are some vague lines on it. It is the equivalent of having a full diapsid skull and saying you found Permian dinosaurs...

A 95 million year old angiosperm leaf preserved as an impression in an iron-cemented sandstone. The original leaf may have gone, but you can still see where invertebrates nibbled it. From Dakota Formation, Kansas. Cenomanian, probably. #FossilFriday ⚒🌏🔬🌱🍃🌳

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. 🔬🌿⛏️ #paleobotany

Pour grandir, les plantes récupèrent divers éléments dans les sols. Certaines d’entre elles sont capables d’en extraire ou d’y dégrader des substances polluantes : c’est le principe de la phytoremédiation.

A selection of #lichens enjoying the very rainy weather around Montpellier these days much more than the rest of us! 💚 #botany

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! #paleobotany #botany

This is my favourite portrait of the moss Bryum capillare, Capillary Thread Moss, on an ancient fallen trunk of Sambucus nigra, Common Elder. The development of corky bark is common with age, but this is a particularly splendid example.

3D models of fossil flowers help reconstruct past ecosystems. Such findings provide analogues to better understand how tropical biomes may respond to ongoing #climatechange. 🌏 Simon’s doctoral research was awarded the museum’s von Pawel-Rammingen Doctoral Thesis Award! 🏆 (3/3) 📸 2023 Beurel et al.

For this #FernFriday and #FossilFriday, let's look at Symplocopteris wyatti, an early fern from the Carboniferous of Australia 🌿⛏️. This #fern formed trees with "false trunks" up to 50 cm in diameter, composed of several branching stems intertwined with petioles and roots #paleobotany 🧵1/3

January 14, 1801, birthday of French geologist & palaeontologist Adolphe-Théodore Brongniart. His pioneering work on the relationships between extinct and existing plants has earned him the title of father of paleobotany 🌿 blog.biodiversitylibrary.org/2015/10/the-...

Attirer efficacement les pollinisateurs est essentiel à la reproduction de nombreuses plantes. Plus anciennes que les plantes à fleurs, les cycadées utilisent la chaleur de façon séquentielle pour faire venir des coléoptères sur leurs cônes mâles puis femelles !

Happy #ThickTrunkTuesday, with this beautiful but not very huggable #tree photographed in the Aswan Botanical Garden a few years ago 🌳 en.wikipedia.org/wiki/Ceiba_s... #botany

Both of the plants in this photo are the “purple pitcher plant” (Sarracenia purpurea). The one on the right has normal pigmentation. The one in the left is a quite uncommon all green variant. Always nice finding these. #botany #plant #pitcherplant #carnivirous, #Newfoundland, Canada.
