Two ‘Lazarus’ Marsupials Confirmed Alive in New Guinea, One Assigned to a New Genus

Peer-reviewed studies confirm the identifications using fossils, museum archives, new photographs, citizen science, Indigenous knowledge.

Overview

  • Researchers verified the pygmy long-fingered possum (Dactylonax kambuayai) and a ring-tailed glider now placed in the new genus Tous (Tous ayamaruensis) after the species were long known only from Holocene fossils.
  • The confirmations draw on reexamined specimens misidentified in the University of Papua New Guinea collections, field images posted by citizen scientists, and local expertise from Tambrauw and Maybrat elders.
  • The studies, led by Tim Flannery and Kristofer Helgen, are published in Records of the Australian Museum with supporting statements from the Australian Museum and the Bishop Museum.
  • Both animals were documented in the remote Vogelkop (Bird’s Head) Peninsula of West Papua, with exact sites withheld to deter wildlife trade and disturbance.
  • Scientists warn of logging and land clearing pressures and call for targeted surveys to map ranges, assess protection within park systems, and guide urgent conservation action in the region.
