袋小齒獸屬

袋小齒獸屬（Nimbadon）是雙門齒目下一個所有種都已滅絕的屬，其下生物生活在中新世。大部份化石發現於澳大利亞的里弗斯利。

1990年在該地一個洞穴中發現了其頭骨化石。據估計其出現於1500萬年前，在1200萬年前滅絕，原因可能是氣候變化和棲息地喪失Fossils reveal prehistoric life cycle , Australian Geographic, July 20, 2010

Nimbadon lavarackorum
Nimbadon lavarackorum與考拉很像，復原圖來自於24具組織結構清晰的化石。這種生物也主要棲息的在樹上，以及植物的莖葉為食。足、爪相對較大，在走動時可以收起爪子。Ancient tree-wombat behaved like a koala  - By Anna Salleh - Australian Broadcasting Corporation - Retrieved 22 November 2012.Black KH, Camens AB, Archer M, Hand SJ. 2012.
