I’m recruiting a PhD student to join our lab in the fall of 2027. If you’re excited about phylogenetics, comp bio, paleobiology, stats theory, macroevolution, etc. please get in touch! Folks at #Evol2026, you can talk to @brpetrucci.bsky.social & @sigournie.bsky.social to learn more about our lab
#Evol2026 has been a blast!! Hope to see some of you mutuals at my talk this evening. Let’s talk about dogs and fossils and dog fossils 😎
Bruno do Rosario Petrucci@brpetrucci.bsky.social · 2mo agoHope to see y'all at #Evol2026! I'll be talking about my simulation tests of cutting-edge fossilized birth-death models, and what we can learn from the Canidae phylogeny using these models. Come through! It'll be on Sunday (June 21st) at 5:15PM, room 22. Last talk first day 🤙

Once upon a time, large bone-crushing dogs roamed across our continent. @restingdinoface.bsky.social takes a colorful look back at the lives of the successful carnivores. www.smithsonianmag.com/science-natu...
What Happened to the Bone-Crushing Dogs That Once Hunted Across North America?
Before going extinct roughly two million years ago, canids known as borophagines took down and consumed much larger prey

Going from reading almost exclusively simulation studies and theory papers to almost exclusively canid systematics/fossil description papers has been an interesting experience! Anyway look at this cool paper about Plio-Pleistocene European foxes! www.sciencedirect.com/science/arti...
Unraveling the fossil record of foxes: An updated review on the Plio-Pleistocene Vulpes spp. from Europe

Updated preprint! Thanks to suggestions from reviewers, we have some new insights on using continuous traits in phylogenetic estimation. And a lot more about dicynodont taxonomy. Seriously, google dicynodonts and tell me you don't want to know what's happening there www.biorxiv.org/content/10.1...
Incorporating continuous characters in joint estimation of dicynodont phylogeny
Continuous characters have received comparatively little attention in Bayesian phylogenetic estimation. This is predominantly because they cannot be modeled by a standard phylogenetic Q-matrix approac...

Having to write an R script to write another script makes me feel like I am in limbo
When a chatbot gets something wrong, it’s not because it made an error. It’s because on that roll of the dice, it happened to string together a group of words that, when read by a human, represents something false. But it was working entirely as designed. It was supposed to make a sentence & it did.
Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.
Very cool paper! Glad to see Bluesky helping me find new cool science hot off the press 🍞

Excellent analysis & commentary by @johnhawks.net on 2024 study of 1.5 mya fossil hominin footprints in Kenya showing 2 different species of humans (Homo erectus & Paranthropus boisei) walking in the same direction, & possibly separated by only a few hours. Ichnology FTW! 🧪🐾🪨

For those who followed me without knowing me (thank you and nice to meet you!), it’s very important for you to know that I am unhealthily obsessed with horseshoe crabs. I don’t even study them at all, and they’ve just been my favorite animal since I found out they existed. They’re the coolest!
Get To Know Nature@gettoknownature.bsky.social · last yr.Just a horseshoe crab doing its thing. Its thing is heading back to the water after a volunteer rescued it from being stuck on its back and left behind by the tide. 😅 I love the scraping noise they make as they move along the sand. #invertebrates 🦀 🌿
1/13 Time to talk about dogs and fossilized birth-death models! Here is a quick run-down of my #Evol2025 talk. 🧵
Thank you so much to all the new and old friends I had the pleasure of speaking to at #Evol2025. Hope I can establish lots of new collaborations and, even more importantly, new connections with these talented folks. See y’all in Cleveland!!
