By integrating fertile #fossils and extant #Osmundaceae, we evaluated their phylogenetic affinities and diversification over time…and made some interesting findings:

1. Our analyses clarified the affinities of Osmundopsis and Cacumen, which were recovered as the stem group of extant #Osmunda.

📢 We're back on Bluesky — and with a new paper ;)

Have you ever wondered how an ancient fern lineage survives millions of years of global change? 🌿

Our new study addresses this by using #fossils, morphology and molecules to reconstruct its deep-time evolution.

Creating a first class compartment on a home-built aircraft makes sense when a first class passenger needs a flight, especially if the passenger has a giant pink backpack larger than a wardrobe.

Happy Fossil Day!
Here's something I didn't know!
Amenites get their name from the Roman writer Pliny the Elder, who thought their coiled fossils looked like the curved ram's horns of the ancient Egyptian god Ammon!

To celebrate #NationalFossilDay we're sharing the story of our paleontology intern Kyra Mauntel & a #research trip she recently participated in. Because the only thing better than #fossils, is sharing science with students and the public. @ashpoust.bsky.social news.unl.edu/article/nebr...

I do have to freely admit, if I was asked to explain what breathing felt like, I'd be hard pressed to give a sensible answer.

(The shopping expedition in the £0 store went well though).

Found these two stones in my son’s garden in Leeds today.
They’re both about 4” long . One is a beautiful fossil the other has a smooth round hole completely through it.

We learn something important at the hospital today:
OXYGEN IS INCREDIBLY HEAVY.

Found this fossil this morning (Valencia, Spain) and I have no idea what it might be. I'm thinking coral? Please help! #fossil #fossilhunting #fossils

A dinosaur long thought to belong exclusively to North America has turned up in Spain, offering a 150-million-year-old clue to how giants moved between continents.
