How did the first plants that colonized land affect the composition of the atmosphere?
PhD fellowship with Tais Dahl (and me) at the @Globe_UCPH institute: reconstructing past climate from palynology and geochemistry🌿
Deadline: 18 January 2024
@Ruth_Mottram @dantheclamman This is great! Thanks Ruth 😊🌿
Mastodon at its best. A thread about #Clams.

Also, can anyone @utrechtuniversity (or anyone else really?) explain why there is a copy of the Jelling stone (Denmark's baptism certificate, more or less) standing outside the cathedral? #JellingSten
For #FossilFriday check out this gorgeous fossil insect! This 49 million year old beauty is Pulchritudo attenboroughi, a beetle found in the rocks of the Green River Formation, Colorado. What's particularly striking about this fossil is the pattern on its wing cases.
An oak is an oak, or not? Understanding and dealing with confusion and disagreement in biological classification (OA)

Classification, especially of species like oaks, is not a straightforward process due to varying interpretations and disagreements. The paper demonstrates how a philosophical approach, the Grounded Functionality Account, can provide clarity on such issues in scientific taxonomy. 🌳
My paper, which reassigned a tiny palynomorphs from a prasinophyte to a dinoflagellate, is now online (accepted manuscript). A truly tiny contribution to understanding ecosystem changes during the end-Triassic mass extinction. 🌿
@botanyone Oooh...sounds interesting 🤩 Will deffo read.

Ernst Haeckel, German biologist, philosopher & artist, died #OTD,1919. He became the most famous champion of Darwinism in Germany. His monumental ”Kunstformen der Natur” influenced science, art & architecture of the early 20th century.

Our work on the evolutionary history of #cycads is out in @newphyt !
We built a #phylogeny with 321 extant and 60 #fossil cycads, and dispelled the myth of the 'living fossil' being left over from the age of the #dinosaurs

Happy #DarwinDay! Charles Darwin was born #OTD 1809. During the first two years of his voyage aboard HMS Beagle, he collected a considerable number of fossil mammals from South America. Those discoveries sparked the theory of #evolution https://paleonerdish.wordpress.com/2016/04/06/darwins-fossil-mammals/
