Happy #InternationalDayofWomenandGirlsinScience - from me and my lab! 🤩 The field of Molecular Paleobiology has been pioneered by women scientists - and I am so proud to be part of it and train the next generation of brilliant minds!💚

Seeing scientific visuals is amazing, but understanding how every detail connects to the bigger picture is crucial! 🧬🔍 Discover the art of accuracy and perspective at smart-biology.com! #biology #3D #science #EdTech #animation

The everyday lives of extinct limbed animals are preserved within their footprints. #Fossil #trackways inform many scientific fields, creating several distinct terminologies. This new glossary defines a consistent, unambiguous terminology usable in all relevant fields.

Announcing the rather epic 'Glossary of tetrapod tracks' in Palaeontologia Electronica. Three years of work led by Jens Lallensack, and with Guiseppe Leonardi (author of the original '87 Glossary). We hope it will be useful for anyone working on tracks palaeo-electronica.org/content/2025/5…

Hmm, in a weirdly morbid way, I really hope this pair of mating Jurassic insects perished on #ValentinesDay The pair of fornicating froghoppers are from China. They are ~165 million years old. You're welcome this #FossilFriday 🪲❤️🪲

Paleotwitter, How should one draw scales of stem tetrapod?? Some group, especially colosteids, known to covered with dermal ossifications, especially on the ventral half sidn (gastralia is composed of chain mail like scales) and dorsally, with rounded smaller scales.

Marjorie Courtenay-Latimer was born #OTD in 1907. In 1938 she found a very unusual fish in a market - a coelacanth, thought to be #extinct. It was later named after her with the generic name of Latimeria. 📷#Sketch by Courtenay-Latimer in "Old four-legs"/ JLB Smith, publ. 1956

A robustly rooted tree of eukaryotes reveals their excavate ancestry nature.com/articles/s4158… nature

How long may elapse between the excavation of a fossil and its publication? #DUONYCHUS, A TWO-FINGERED THERIZINOSAURID is: Found in 2012. Portrayed in paleoart in 2015 (art by Masato Hattori). ... ... ... DESCRIBED IN 2025 (publication apparently not online yet. News came first).

Preprint alert: "Mating signal energy gradient mediates gene flow in the early stage of avian speciation". We studied 109 pairs of hybridizing bird species & unveiled some hidden roles of their magical mating rituals. #birds #evolution

Here are the 109 pairs of avian species across the most up-to-date Aves phylogeny. Preprint link: biorxiv.org/content/10.110… #BirdsOfTwitter #Science

The reason biologists in your timeline are furious by this PR: the idea that species that diverged millions of years ago have only 20 genetic differences defies the fundamental principles of evolution. Like saying you turned a Honda Civic into a Formula 1 car by changing the oil

Why is this so bad? Because the Secretary of the Interior is already using "de-extinction" as an excuse to remove species from the Endangered Species List x.com/SecretaryBurgu…
