Is the red-bellied gracile opossum an extinct animal?

Yes, the red-bellied gracile opossum (Gracilinanus ignitus) is considered an extinct animal. It was a small, carnivorous marsupial endemic to the Australian state of Queensland. This species was last recorded in 1890, and extensive surveys conducted since then have failed to find any evidence of its presence. Therefore, the red-bellied gracile opossum is now classified as extinct by the International Union for Conservation of Nature (IUCN).
