Let me introduce you to Tametara mirim, a basal Cretaceous snake from South America that was likely fossorial. It is known from a beautifully preserved and articulated specimen that includes a skull! If you know anything about snake fossils you will know that is VERY rare #snakes #paleoart

I’ll take part on #FossilFriday today with a photo from our new fossil Tametara mirim, the tiny jewel from the Brazilian Cretaceous 😊

Estudo publicado em @nature.com mostra que a Tametara mirim vivia no subsolo, enquanto uma espécie contemporânea da Argentina vivia na superfície, indicando que já havia uma diversidade ecológica de #serpentes estabelecida 80 milhões de anos atrás. agencia.fapesp.br/58763

Our co-author @ebelosaurus.bsky.social wrote a piece for @theconversation.com on the newly published fossil snake from Brazil :) theconversation.com/80-million-y...

80-million-year-old snake fossil sheds light on why lizards lost their limbs and started slithering

Snakes lost their limbs millions of years ago to become undulating, scaly tubes of muscles. Scientists are finally figuring out why.

Cool detailed account by @sobralg.bsky.social on some of the back stage stories behind our paper

So, I will take the opportunity to write about our paper on the new fossil snake 🐍 from Brazil out in @nature.com today. Tiago wrote on the science itself here 👇 so I will tell a bit about the behind the scene stages, especially segmentation and anatomical interpretation bsky.app/profile/trsi...

Proud to share our latest paper in out in Nature today on the origin of #snakes. We present Tametara mirim, an articulated 3D preserved stem snake from the Late Cretaceous of Brazil. Tametara helped us re-tell the story of snake origins in a novel way... www.nature.com/articles/s41...

Excited to see our work with @trsimoes.bsky.social and @anniehsiou.bsky.social published in Nature @nature.com 🐍 Early snake evolution was more dynamic than expected, spanning diverse habitats and sensory strategies 🐍 @helsinki-biotech.bsky.social @helsinki.fi www.nature.com/articles/s41...

Our work is out! Meet Tametara mirim, a new fossil snake 🐍 from Brazil that has challenged our views on early snake evolution!

Want a summary of the recently published paper of @semifossorial.bsky.social and colleagues on @currentbiology.bsky.social and understand the implications for reptile and turtle evolution? Here it is! I hope you have as much fun reading as I had writing it :) www.sciencedirect.com/science/arti...

Back to work after a week off and I feel my brain has not returned from vacations

my external HD is corrupting the files I am working with, not my laptop.... now I'm really worried :(

This review was inspired by my recently started Turtle Origins Research Group @smnstuttgart.bsky.social and @unihohenheim.bsky.social funded by a @dfg.de Emmy Noether Grant, which will deal more with this subject. So much more to come! For now, please enjoy: www.tandfonline.com/doi/full/10....

Getting to the root of it: perspectives on the phylogenetic origins of modern reptiles

Reptiles are currently represented by turtles, archosaurs (crocodylians and birds), and lepidosaurs (lizards, snakes and the tuatara). However, these groups represent only a fraction of the known d...

So apparently all the files that I opened in my old laptop in the past week got corrupted when I saved it on my external HD :(

One IPC7 abstract finished, the second one to be done soon. Hopefully I can submit them Monday morning :)

New in @science.org ...since our first discoveries of early tetrapods, they have been thought of as "amphibians" characterized by aquatic larvae. But is this true? For the first time, we report exceptional fossils of stem tetrapod babies that upend this paradigm. 1/n www.science.org/doi/10.1126/...

Direct development of stem tetrapods across the fin-to-limb transition

Modern amphibians are characterized by an aquatic larval stage that ends abruptly with a period of widespread tissue remodeling (metamorphosis) upon transition to terrestrial adulthood. A transient la...

Every time I come accross the word "shorebird," I read it as "sorebird" #TheDailyDyslexia

Here's a thread of #books I've recently got hold of. I'm obsessed with zoology, and all are animal books. We start with Des Thompson and Ingvar Byrkjedal's Shorebirds of 2001. On first glance, it looks like one of those photo-themed bird books that contain minimal info, but...

OMG it is amazing how incredibly dumb Google now is, thanks to their idiotic IA model. I was looking for information on Eubaena cephalica, and it only showed me results for "vena cephalica" and I did not find a way to turn it off and show me results for the actual words I typed in!

two hours to describe the prootic ugh

Today work finished a bit earlier to watch the opening World Cup match :P

a warm welcome to silescelida acristata 🎉 this is a new eucrocopodan archosauriform from middle triassic brazil, described by garcia et al. based on partial, disarticulated postcranial elements (art by @mfgadelha.bsky.social) www.nature.com/articles/s41...

Another off-campus visit to connect with other palaeontologist in the area. Hopefully we can bring some of the plans out of the field of ideas :)

Almost made the “booked a hotel close to the wrong conference venue” mistake

Great news on a holiday! Paper incoming 🥳

spent the morning adjusting for a backbone topology and the results were pretty much the same 😒
