Le professeur Paul Barrett du Natural History Museum de Londres a récemment écrit A History of Dinosaurs in 50 Fossils. Nous en avons profité pour avoir un aperçu de ce que nous savons réellement sur les dinosaures et comment il est même possible de raconter leur histoire avec seulement 50 spécimens. Dans cet épisode, Paul discute de l'histoire [&hellip

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.

Chine Crétacé Crétacé inférieur juvénile spécimen Dinosauria Haolong
 Cette semaine, nous allons découvrir un dinosaure nouvellement décrit qui est si unique qu'il change complètement ce que nous pensions savoir sur la peau des dinosaures !  Entrez Haolong Dongi ! 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
