Summary
| Description |
English: In 1982 paleontologist Dale Russell, curator of vertebrate fossils at the National Museum of Canada in Ottawa, conjectured a possible evolutionary path that might have been taken by bipedial predator dinosaurs if they had not all perished in the K/T extinction event 65 million years ago. A few scientists have followed Russell's idea, but many are highly skeptical.
Français : En 1982, le paléontologiste Dale Russell, conservateur des fossiles vertébrés au Muséum national du Canada (National Museum of Canada) à Ottawa, émet l'hypothèse d'une possible voie d'évolution empruntée par des dinosaures bipèdes qui n'auraient pas péri durant l'extinction Crétacé-Tertiaire il y a 65 millions d'années.
Italiano: Nel 1982 il paleontologo Dale Russell, curatore dei vertebrati fossili per i musei nazionali del Canada a Ottawa, ipotizzò un possibile percorso evolutivo che avrebbe potuto essere intrapreso dal troodonte, un dinosauro predatore bipede, se non fosse scomparso durante l'estinzione di massa del Cretaceo-Paleocene avvenuta circa 66 milioni di anni avanti Cristo. |
