Haolong original spikes finally out in @NatureEcoEvo🇨🇳🐉🦔 - make it live! @nat_sciences_be @CNRSecologie @CNRS_INSU @GeosciencesR @RennesUniv @PalaeoPittman @IAB_Officiel @PaleoAppi and Anhui Geological Museum of @HefeiChina #dinosaur #fossilskin #Jeholbiota #paleohistology
#PressRelease🗞️ Documented for 200 years, the Iguanodontia group is expanding with the discovery of a brand-new species, the first known to bear spikes with properties never before observed in dinosaurs.

There is amber in Belgium! It is 50 myo and it so far yielded a handful of animal inclusions: a termite, a true bug, a mite... this new 🇧🇪 report is a ladybird🐞- a coccidulini. @nat_sciences_be @OSURennes @Le_Museum #belgium #entomology #fossils #ladybird

Crinoid tube feet recovered from the Ordovican of Canada! Their organisation reveals these crinoids fed in a wider ranger of postures than most modern stalked crinoids, in a way convenient to feeding in low-energy environments 🇨🇦 #echinoderms #softtissues

Implications of trematod (flatworms) parasitic infestation on bivalve shells🦠, traced in the fossil record of Florida 🇺🇸 (through observable pits and scars).

Just out!
We wondered what information is retained in the elemental chemistry of an animal poop💩that has fossilized - can it be used as a proxy, and of what?

Herbivorous terrestrial microsaurs from the late carboniferous reveal this diet was ancestral to the divergence of amniotes 🌱🌿🌱(article with the late Hans Dieter Sues from the Smithsonian, how sad)

A paper on Early Permian scale impressions (of bolosaurian reptiles). It is difficult to interpret the origin of a tissue from imprints; but it is most likely dermal indeed🦎 #paleontology #fossilskin #softtissues #ichnology #footprints #scales

The paleo community is mourning the passing of giant. Philippe Taquet passed away on Sunday at 85. I was honored to meet him in his Paris office in 2007. Later that year, we published on a sauropod from his beloved Gadoufaoua in Niger & named for him: bit.ly/3WZLKdF
ALT Philippe Taquet & Witmer in Dr. Taquet's office (19 July 2007, Paris)
ALT Restored skull and brain endocast of the rebbachisaurid sauropod dinosaur Nigersaurus taqueti (MNN GAD512). Published in November 2007 in PLOS ONE (Sereno et al. 2007: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0001230).
2001 - In my kidbed, reading in his book "L'empreinte des dinosaures" that studying fossils sometimes also offers the chance to travel far abroad and thus to meet people from all over the world.
Meaningly grateful that I was able to try 🙏

Out in IScience: "A 480 million year old parasitic spionid annelid"....or so many other type of extant or extinct annelid? I find this one moderately convincing (though interesting ofc !) 🪱

BIG DAY TODAY FOR PARASITOLOGY 🪱
The first leech body fossil (previous occurences being triassic cocoons 🥚) - recovered as a stem-Hirudinida from the Silurian period (>435 ma). 🥳

Bayesian modelling of the fossil record enlightens the evolutionary history of Hemiptera. Congrats to all authors, especially @ISYEBsp ones.
The only thing I really expect from academia is to have fun. 🎉
This paper is pure fun: it started with a BBQ brainstorming, turned into a project with friends, and ended with a super-talented friend making the cover photo. What a combo! 🔥📚📸
