Squelette de Phascolonus Gigas Musée américain d'histoire naturelle New York // NEW YORK CITY, États-Unis — le Musée américain d'histoire naturelle expose ce squelette de Phascolonus gigas (wombat géant) moulé dans la zone de transition entre l'aile David H. Koch Dinosaur et l'aile Lila Acheson Wallace des mammifères et de leurs parents disparus. Recueilli en 1970 par C. E. Ray dans le lac Callabonna, en Australie méridionale, ce fossile marsupial a vécu il y a environ 100 000 ans à la fin du Pléistocène. L'exposition met en évidence les deux caractéristiques dentaires marsupiales avec des cuspides triangulaires pour une efficacité efficace

Photograph by David Coleman. The American Museum of Natural History features this cast skeleton of Phascolonus gigas, an extinct giant wombat, at the transition point between the David H. Koch Dinosaur Wing and the Lila Acheson Wallace Wing dedicated to Mammals and Their Extinct Relatives. This significant specimen (AMNH 129499) was collected in 1970 by C. E. Ray from Lake Callabonna in South Australia. Phascolonus gigas lived approximately 100, 000 years ago during the Late Pleistocene era and represents one of Australia's megafauna species that became extinct relatively recently in geological time. The exhibit highlights the evolutionary relationship between marsupials and placental mammals, noting that marsupials like this giant wombat are the closest relatives to placental mammals—the group that includes humans. The display emphasizes distinctive dental features, specifically the three bumps or "cusps" arranged in a triangular pattern on the molar teeth, an adaptation that enabled efficient chewing in both marsupial and placental mammals. This particular fossil also preserves a remarkable taphonomic feature: a footprint impression on the skull made by Diprotodon, an even larger marsupial that apparently stepped on the wombat's skull after death. This rare instance of fossil interaction provides an unusual glimpse into the physical relationship between two extinct megafauna species in prehistoric Australia.
