Rates of skeletal character evolution in the skull and postcranial skeleton of hadrosauroids. Cladograms illustrate the results from branch likelihood tests for two morphological partitions: skull (cranium and mandible) (A) and postcranial skeleton (B). In both cladograms, results from the branch likelihood tests are summarized on a strict consensus tree derived from four separately analyzed MPTs, each with 100 dating replicates (a total of 400 Hedman-dated phylogenies). Pie charts on branches illustrate the proportion of dating replicates that showed significantly high rates (red), slow rates (blue), or nonsignificant average rates (white). No pie charts are plotted on branches that showed nonsignificant rates in 100% of dating replicates. Branches that showed high rates (red) in more than 50% of dating replicates are doubled in length. See the Supplementary Material for Hedman-based results plotted separately for each MPT (Supplementary Fig. S2) and for results using the MBL dating method (Supplementary Fig. S3). Silhouettes were created by Scott Hartman and were downloaded from http://phylopic.org (Creative Commons license CC BY 3.0).

Ce « crocodile terroriste » de 31 pieds mangeait des dinosaures. Maintenant c'est de retour
prédateur musée États-Unis Dinosauria squelette
Un énorme « crocodile terroriste » de la taille d’un bus qui s’attaquait autrefois aux dinosaures a été ramené à la vie avec des détails époustouflants grâce au premier squelette complet scientifiquement précis de Deinosuchus schwimmeri. S'étendant sur plus de 9 mètres de long, cet ancien prédateur suprême régnait sur le sud-est des États-Unis il y a plus de 75 millions d'années. Les visiteurs peuvent désormais le voir de près au Tellus Science Museum, le seul endroit au monde à posséder cette réplique.

fossile Alnashetri Alvarezsauria Dinosauria oiseau évolution squelette
Un squelette de dinosaure presque complet découvert en Patagonie aide les scientifiques à percer le mystère des alvarezsaures, un groupe étrange de dinosaures ressemblant à des oiseaux. Le fossile d'Alnashetri cerropoliciensis révèle que ces animaux sont devenus minuscules avant de développer leurs caractéristiques spécialisées ultérieures, telles que des bras tronqués et des adaptations mangeuses de fourmis. Pesant moins de deux livres, le dinosaure est l’un des plus petits connus d’Amérique du Sud.

Royaume-Uni Jurassique fossile Ichthyosauria évolution squelette
Un ichtyosaure nouvellement identifié de la côte jurassique du Royaume-Uni est en train de réécrire une partie du manuel préhistorique. Surnommé le « dragon-épée du Dorset », ce reptile marin de trois mètres de long a vécu pendant une période d’évolution mal comprise, au cours de laquelle les principaux groupes d’ichtyosaures disparaissaient et de nouveaux apparaissaient. Son squelette magnifiquement préservé – doté d’un museau en forme de lame et d’un éventuel dernier repas – permet de déterminer le moment où cette transition dramatique s’est produite.

Mexique États-Unis Trias supérieur Trias fossile squelette
Cette semaine, nous allons découvrir un parent de crocodiliens modernes qui a trompé les scientifiques à plusieurs reprises !  Entrez Hesperosuchus agilis ! Hesperosuchus était un pseudosuchien (lié aux crocodiliens) qui vivait dans ce qui est aujourd'hui l'Arizona et le Nouveau-Mexique, aux États-Unis, à la fin du Trias, il y a environ 210 millions d'années.  Il s'agissait probablement d'un mangeur de viande et, du museau à la queue, le squelette le plus complet mesure environ 1,2 m (4 pieds), mais d'autres fossiles suggèrent qu'il aurait pu devenir plus grand, jusqu'à environ 1,2 m.

Une maladie perdue émerge de restes humains vieux de 5 500 ans
Colombie évolution squelette
Un squelette colombien vieux de 5 500 ans a révélé le plus ancien génome connu de la bactérie liée à la syphilis et aux maladies associées. L’ancienne souche ne rentre pas parfaitement dans les catégories modernes, faisant allusion à une forme oubliée qui s’est divisée au début de l’évolution de l’agent pathogène. Cela repousse l’histoire des maladies tréponémiques dans les Amériques de plusieurs millénaires et montre qu’elles se diversifiaient déjà bien avant les documents écrits.
