Cette petite griffe dans un fossile vieux de 500 millions d'années vient de réécrire l'origine des araignées
griffe Cambrien fossile spécimen
Ce qui a commencé comme un nettoyage de routine des fossiles s'est transformé en une surprise scientifique majeure lorsque des chercheurs ont découvert une petite griffe dans un spécimen vieux de 500 millions d'années, là où aucune griffe ne devrait exister. Ce détail a révélé Megachelicerax cousteaui, le plus ancien parent connu des araignées, repoussant les origines de ce groupe de 20 millions d'années. Le fossile montre que les principales caractéristiques des araignées et des limules modernes étaient déjà apparues lors de l'explosion cambrienne.

Haolong était un dinosaure herbivore qui vivait dans ce qui est aujourd'hui le Liaoning, en Chine, au début du Crétacé, il y a environ 112,5 millions d'années.  Le seul spécimen enregistré mesure environ 8 pieds (2,45 m) du bec à la queue, mais il était juvénile lorsqu'il est mort, l'espèce a donc probablement grandi.  Le nom du genre se traduit du chinois par "S

Le Tyrannosaurus rex a peut-être mis beaucoup plus de temps à grandir que les scientifiques ne le pensaient autrefois. En analysant les anneaux de croissance des os fossilisés des pattes de 17 spécimens de tyrannosaures et en utilisant de nouvelles méthodes statistiques, les chercheurs ont découvert que le célèbre prédateur avait probablement mis environ 40 ans pour atteindre sa taille maximale, soit environ huit tonnes, au lieu des 25 ans précédemment estimés.
