The eleven organisations, including the CNRS, that won the European Equality Prize signed a declaration of principle in support of gender equality in research.

This involved empirical data collection on an ontogenetic spectrum of gators in Florida (several papers by Iijima & Blob recently) & using these in inverse dynamic simulations to estimate muscle forces & activations across body sizes. Simulation of right hindlimb shown; red colours = active muscles

New paper on crocodylian locomotor evolution led by Masaya Iijima, w/Richard Blob & me! More erect hindlimb postures help extant gators support their weight (esp. at ankle), & how these mechanics constrained giant Deinosuchus to a slow walk at best! The paper-- www.science.org/doi/10.1126/...

J'étais ce we à Cruzy pour l'inauguration de l'expo paléo de l'ACAP sur laquelle j'ai travaillé en tant que commissaire scientifique. Bravo aux bénévoles pour leur engagement et pour le travail accompli ! 👏 Si vous êtes dans les parages, n'hésitez pas à venir leur rendre une petite visite ! 😉🦕

My comment: Is scale loss always part of evolving a pelagic lifestyle? Is Is always about swimming? Maybe - or maybe not. Conclusion: More fossils and research needed🤩🧪 www.science.org/content/arti...

Interesting new study about scale loss evolution in turtles, with the oldest soft tissue preserved in a sea turtle 🐢 www.sciencedirect.com/science/arti...

Excited to share our new paper where we find that the rise, decline and fall of clades is not explained by the usual suspects (diversity-dependence, ecological opportunities) but rather by species' insidious loss of macroevolutionary fitness: www.nature.com/articles/s41... 1/3

‪ Nouvelle expo dans le jardin du @mnhn.fr sur les Savanturières, avec, parmi les chercheuses exposées, une paléontologue ! Nathalie Bardet @cr2p.bsky.social

Fish suck... but species that feed on algae suck differently! 🐟 A new publication in Communications Biology by #UAFunMorph members Jana De Ridder, Peter Aerts, and Sam Van Wassenbergh, demonstrates how head motion patterns for generating suction are finetuned to the species' main diets.

New paper @journalsystpal.bsky.social with Drew Moore @stonybrooku.bsky.social re-evaluating diplodocoid sauropod dinosaur phylogeny + biogeography, including illustrating synapomorphies, with implications for the early evolution of the major lineages: doi.org/10.1080/1477... @es-ucl.bsky.social

This study demonstrates that sabre-tooth canine shape is exceptionally diverse. A functional analysis of theoretical and actual tooth shapes shows that these canines represent a compromise between sharpness, curvature, and length vs. robustness and material investment.

Great expectations: altricial developmental strategies are associated with more flexible evolution of limb skeleton proportions in birds #ProcB #OpenAccess #Developmental Biology #Evolution royalsocietypublishing.org/doi/10.1098/...

To a certain amount, you can estimate the angle of the ankle joint (mean angle during stance phase) of some land mammals by measuring the angle of their tibial long axis vs. calcaneal tuber long axis, and that could be handy: peerj.com/articles/200...

Hello, microanatomy &/or salamander enthusiasts! If you’re a first-year master’s student, I might have an exciting internship for you on the microanatomy of two salamanders sp., with already great results on the humerus. What: Zeugopod microanatomy Where: SMNS Contact: [email protected]

A new ichthyosaur species is discovered! Welcome Eurhinosaurus mistelgauensis! fr.pensoft.net/article/1542... Huge congratulations to @spichergael.bsky.social for leading this project.

This is one of those fossil specimens that when I saw it for the first time at SVP it literally made me gasp. A beautiful and very important specimen.

We studied the microanatomy and histology of vertebral centra from Grippia and Cymbospondylus from the Early Triassic of Spitsbergen. First look during covid times, then we realized we had series with all ontogenetic stages, the smallest one a 5 mm fetal vertebral centrum.

"Growth series", with foetus, of two very distinct ichthyosaurs from the Triassic! Very glad to have participated to this cool study! Thanks again Lene!
