How Do Vertebrate Droppings Fossilise? Biogenic Versus Diagenetic Signals in Coprolites Evidenced by Elemental Mappings μXRF was applied to sections of 140 Ma fossil vertebrate droppings of different morphologies. The results reveal homogeneity of the carbonate-fluorapatite matrix and elemental compositions driven by ...

Out! We wondered what information is retained in the elemental chemistry of an animal poop 💩 that has fossilized - could it be a proxy? 🐊🦖🐢

Carboniferous recumbirostran elucidates the origins of terrestrial herbivory - Nature Ecology & Evolution A new species of pantylid microsaur from the Late Carboniferous of Cape Breton Island, Nova Scotia, has teeth with dental occlusion consistent with herbivory, indicating an early transition to this co...

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)

Le tout premier dinosaure à piquants a été découvert en Chine Il s'appelle Haolong dongi. Ce dinosaure herbivore d’environ 2,5 mètres portait des piquants a été découvert au Nord-Est de la Chine. Une nouvelle étude révèle une structure cutanée inédite chez les d...

Il s'appelle Haolong dongi. Ce dinosaure herbivore découvert au Nord-Est de la Chine porte une structure cutanée inédite : ni plumes ni simples filaments mais de petits piquants rigides. A quoi ressemblent ces épines ?

(et oui, j'ai galéré à dire ornithischiens 😅

The earliest reptile body impressions with scaly skin Marchetti et al. describe Cabarzichnus, the first definite body impression of stem reptiles, specifically bolosaurians. Cabarzichnus includes the earliest fossil evidence of epidermal scales and a clo...

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