Dans le cadre des Grandes Conférences de l'Alliage, Jean-Sébastien Steyer, docteur en paléontologie, raconte son métier et ses techniques.
Comment les paléontologues, ces Sherlock Holmes du passé, reconstruisent-ils les espèces disparues à partir de fossiles souvent fragmentaires ? Quelles sont leurs méthodes et leurs techniques d'investigation ? Des squelettes des Muséums à Jurassic Park, comment démêler le vrai du faux ? Enquête dans les coulisses du métier de paléontologue.
En savoir plus
Jean-Sébastien Steyer est l’un des rares spécialistes qui étudie la vie sur Terre avant les dinosaures. Il travaille par ailleurs sur les reconstitutions d’espèces disparues depuis bientôt une vingtaine d’années. Auteur de nombreux articles scientifiques, ce passionné de vulgarisation publie régulièrement des ouvrages qui font vite référence comme "La Terre avant les dinosaures (2009), "Exquise planète" (2014), ou encore "Demain, les animaux du futur" (2015). Il est également, entre deux expéditions paléontologiques aux quatre coins du globe, chroniqueur scientifique pour les revues "Pour la science" et "Espèces".
