來自澳洲河景世界遺產區的令人興奮的古生物學新聞，正在重塑我們對古代有袋類動物的認識。
Exciting paleontological news from Australia’s Riversleigh World Heritage Area is reshaping what we know about ancient marsupials.
2026年中期發表的研究，發現了一種名為「奇努納原獸目」(Keeunamorphia)的未知有袋類動物的新證據。
Recent studies published in mid-2026 have uncovered evidence of a previously unknown order of marsupials called Keeunamorphia.
在這些發現中，研究人員辨識出了如 Phantasmodon travouilloni 等物種，為研究一個久已失傳的演化分支提供了視窗。
Among the discoveries, researchers identified species like Phantasmodon travouilloni, which offer a window into a long-lost evolutionary branch.
此外，一種名為 Miyumba chrisdickmani 的物種發現，有助於解決一個重大的科學謎團。
Furthermore, the discovery of a species named Miyumba chrisdickmani has helped solve a major scientific mystery.
過去因缺乏化石，導致袋鼬科(dasyurids)——即包括現代袋獾的家族——出現了「幽靈譜系」。
Previously, a lack of fossils created a 'ghost lineage' for dasyurids—the family that includes today’s Tasmanian devils.
這項發現將袋鼬科的紀錄向前推進了500萬年。
This find pushes the dasyurid record back by five million years.
這些發現證實，澳洲有袋類動物的演化並非簡單的單一途徑，而是一個由重疊譜系構成的複雜網絡。
These discoveries prove that Australian marsupial evolution was not a simple, single path but a complex web of overlapping lineages.
透過分析這些古代牙齒遺骸，科學家終於填補了我們對於有袋類動物如何在整個大陸多樣化演變的知識空白。
By analyzing these ancient dental remains, scientists are finally filling the gaps in our understanding of how marsupials diversified across the continent.
這些發現凸顯了澳洲自然歷史的驚人深度，並強調了我們與古老岡瓦那超大陸之間持久的聯繫。
These findings underscore the incredible depth of Australia's natural history and highlight our enduring connection to the ancient supercontinent of Gondwana.
