We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Honey possum — The honey possum was first described by Paul Gervais and Jules Verreaux on 3 March 1842: The correct authorship is Gervais alone, not jointly credited to Verreaux.
Honey possum — A second species, Tarsipes spenserae, was described five days later by John Edward Gray: The exact interval of 'five days' is not a widely established canonical fact and is likely inaccurate.
Quoll — Fossil species have been found in Pliocene and Pleistocene deposits in Queensland, including D. dunmalli, the oldest recovered species — this is inaccurate because older quoll fossils from the Miocene exist.
Quoll — A female quoll can give birth to up to 30 pups, but only as many as her teats (six or seven) can be raised — the number of teats varies by species and is not universally six or seven.
Marsupial — Most marsupials have separate openings for the digestive and urogenital tracts rather than a true cloaca is factually incorrect; most marsupials do have a true cloaca.
Marsupial mole — The claim that 'all marsupials possess a true cloaca' is incorrect; most marsupials have separate openings, and a true cloaca is present in monotremes, not marsupials.
Marsupial mole — The dental formula for marsupial moles is I 4/3, C 1/1, P 2/2, M 4/4 × 2 = 42, not I 4/3, C 1/1, P 2/3, M 4/4 × 2 = 44.
Opossum — The entry states that opossums are 'the largest order of marsupials in the Western Hemisphere,' but the largest order is Didelphimorphia, which is correct; however, the number of species is given as 'around 100–110 species in 18 genera,' but current accepted e
Peramelemorphia — The 'Did You Know' section incorrectly states that the oldest known peramelemorphian fossil as of 2013 dates to the late Eocene or early Oligocene, while Bulungu muirheadae is from the Eocene, creating a false contradiction; in fact, Bulungu muirheadae is itse
Phalangeriformes — The claim that the classification follows Ruedas & Morales 2005 is not a widely-known canonical fact; the correct widely-cited classification for Phalangeriformes is typically attributed to Aplin & Archer 1987 or more recent molecular studies, not Ruedas & Mor
