🚨 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 🦕📉🖥️

[Christopher Dean @PrincessQuatris]

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!!

[Dr Emma Dunne @emmadnn]

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!

@JGarciaGiron @AAlechiarenza No problem! I think this kind of interdisciplinary approach to deeptime work is really fascinating, and should be where people are pushing the field of palaeo. Looking forward to what you all put out next!

[Christopher Dean @PrincessQuatris]

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

Fully funded 4-year conservation palaeobiology PhD studentship with me @ES_UCL using the fossil record of birds to evaluate the impact of climate + early humans on their taxonomic and ecomorphological diversity over the last few million years 🐦🦅🦆🦤🦜 https://t.co/ZeJbuZURj6

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 https://t.co/6mafv3QpJO @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🗓️

[Christopher Dean @PrincessQuatris]

@PeterJWagner6 Truly, truly gutting.

[Christopher Dean @PrincessQuatris]

@palaeo_neil Huge congrats Neil!!!!

Glad to see our @ThePalaeoverse preprint out in @EarthArXiv while is in review at @MethodsEcolEvol 🦖💻📊 Interested in Analytical Paleobiology, full reproducibility and #OpenScience? Send across your feedback or simply play with the development version on @github #RStats 🦕💻📈

[The Palaeoverse Community @ThePalaeoverse]

It’s here! We are very pleased to share our preprint introducing the palaeoverse R package📦, hosted on @EarthArXiv.🌍

Our recent fieldwork in the early Paleocene Punta Peligro area of Patagonia, Argentina 🇦🇷, finding lots of crocodile, turtle, & mammal fossils 🐊🐢🦥, with @poldiego, @yatachelys, @piginatutu, @MirantaKouvari, @SReuil & others @ES_UCL @mefpatagonia @royalsociety & @NatGeo-funded

[Struan Henderson @struhenderson]

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! https://t.co/hqu4bw0gSa

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. 🔍🌍📈

[Dr Thomas Clements @Thomas_Clements]

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!

[The Palaeoverse Community @ThePalaeoverse]

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. 📈🌍

[The Palaeoverse Community @ThePalaeoverse]

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.
