🚨 NEW PAPER 🚨
Very excited to see our paper lead by @Tweetisaurus out in @RSocPublishing today!
We used a variety of methods to assess biogeographic signals in Late Cret. N. American dinosaurs, and found that observed patterns are likely to result from sampling bias 🦕📉🖥️

Slightly delayed to the party, but strongly recommend checking out this very exciting research from Emma et al.! A great example of some of the neat techniques that are allowing us to answer big questions in palaeo. Congrats to all the authors!!
How did the dinosaurs become so successful? 🦕🦖
Check out our newest paper where we looked at how climate played a key role in their early evolution!

ALT Graphical abstract displaying key results of paper. In summary: During their early evolution, sauropodomorph dinosaurs were excluded from the hottest, low-latitude climate zones. Dunne et al. show that the geographic expansion of sauropodomorphs after the end-Triassic mass extinction was facilitated by climatic change, supporting the key role of climate in the ascendancy of dinosaurs
More super exciting work by @JGarciaGiron and @AAlechiarenza on community networks and their structure before and after the K/Pg extinction. Congratulations to the team!

We used 1600 fossil occurrences of non-marine vertebrates from North America to explore the trophic & niche dynamics across the K/Pg mass extinction

Our new bird is coming out today in @Nature!
Meet Janavis finalidens, a large gull-like toothed bird with lots to say about the evolution of modern birds. Janavis’ palate overturns more than 150 years of ornithological paradigm!

New paper led by Loredana Macaluso @unito on the fossil record of Palearctic salamanders, which we evaluate to explain how their present-day enigmatic and disjunct distribution reflects regional extinctions caused by tectonic + climatic drivers doi.org/10.1098/rsos.220935 @ES_UCL

The `time_bins` function can be used to extract intervals from the Geological Time Scale:
- Generate bins using interval names
- Generate bins using age values
- Generate bins at different ranks
- Generate near-equal-length time bins
- Plot bins

It’s officially one week since palaeoverse v1.0.0 has been available on CRAN! 😲
Let’s start introducing available functionality!🔧
We’ll share a function a day over the coming weeks🗓️

Coming out scarily close to my first chapter, my second PhD chapter is now published! I wish I could say that this rapid succession of papers was planned along, but it really wasn't 😅 Thank you so much once again @GilesPalaeoLab and @emmadnn! royalsocietypublishing.org/d…
Choose your own adventure: does this facial expression indicate a childlike sense of wonder or two functioning brain cells? You decide.
Happy Monday followers! It's time to introduce @PrincessQuatris:
Hey! I'm a postdoc at UCL interested in how biases shape our perception of diversity and macroecology in deep time. I'm currently working on applying occupancy modelling to the fossil record. 🔍🌍📈

Very grateful to the Scientific American team for the write up about our recent taphonomy paper!
You can read about how sticking pH probes where the sun don't shine in dead seabass helps us understand how some fossils form here!

First up we have @sofiaGA96:
Hola! I am a biology PhD student at Universidade de Vigo (Spain) studying the impacts of deep-time climatic change on species diversity and their distribution. I am also interested in biases in current and fossil biodiversity data. 📈🌍
We feel it's high time we introduced the faces behind #palaeoverse 👩💻, and Monday seems as good as any time to start! Over the next couple of weeks, we will introduce a different member of the team each day 👋...

WHAT KILLED THE CRABS?
The official story is something like “a billion snow crabs disappeared.”
If that sounds fishy to you, keep reading. Let’s dive into the ecology, oceanography, & geopolitical history of the Bering Sea.
A science thread on crabs, corruption, & collapse: 🦀
ALT CBS EVENING NEWS > Alaska snow crab season canceled as officials investigate disappearance of an estimated 1 billion crabs
ALT News 1 billion crabs go missing, causing cancellation of Alaskan snow crab season

ALT The Washington Post Alaska’s snow crabs have disappeared. Where they went is a mystery.

Wow!🤯
We’ve been live for just 24hrs and there are so many faces here. Thanks for joining!
For those that missed our initial tweets earlier in the year, we wanted to say a little bit about what palaeoverse is…
Also the logo @MirantaKouvari and @piginatutu designed is so cool. They turned the R hex into a cube! Mind blown 🤯
In the mean time, check out our new and improved logo, designed by the fantastic @MirantaKouvari and @piginatutu!
Palaeoverse has a Twitter account!
🦕🦖🦣🐚💻📈📊
Super excited to be involved in this project, and can’t wait to show you what we’ve put together. Give us a follow for all the info, landing very soon!!👇
