1903. Photographed in the BMNH, and reproduced courtesy of the Leeds family, with layout by J. J. Liston. Note

the similarity of this photograph to the drawing of the skeleton in Woodward (1905); previously figured in Anon. (1924) and Naish & Martill (2008).[1][2]

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).

Une « plante grimpante des sables » géante vieille de 240 millions d’années découverte cachée dans un mur de soutènement
dent prédateur Australie fossile découverte squelette
Un fossile oublié caché dans un mur de jardin s’est avéré être l’une des découvertes préhistoriques les plus remarquables d’Australie. Les scientifiques ont maintenant identifié l'amphibien Arenaerpeton supinatus, vieux de 240 millions d'années, révélant un squelette presque parfaitement conservé, avec de rares traces de peau. Cet ancien prédateur de rivière, mesurant environ 1,2 mètre de long, ressemblait un peu à une salamandre géante, mais il était plus volumineux et armé de redoutables dents en forme de crocs.

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.
