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.

Baurusuchidae — The entry states that Baurusuchidae fossils have been found in Asia (Pakistan), but the only Asian genus mentioned, Pabwehshi, has been reassigned to Sebecia, so no confirmed baurusuchid fossils are known from Asia.
Baurusuchidae — The entry says 'Baurusuchus was the first named and gives the family its name' and later 'Baurusuchus was the first, being the namesake of the family', but Cynodontosuchus was named in 1896, earlier than Baurusuchus (1945), so Baurusuchus was not the first nam
Carnosauria — The claim that Concavenator preserves skin impressions showing small scales and scutate scales is not supported by scientific literature; its known integument is limited to possible quill knobs, not preserved scales.
Carnosauria — The claim that the last definitive carnosaur family, Carcharodontosauridae, became extinct exactly 90 million years ago in the Turonian is an oversimplification; some potential late-surviving members may extend into the Santonian or later, and the exact date i
Crocodylia — The entry states Crocodylia appeared 83.5 million years ago, but the oldest known crown-group crocodilian fossils are from the Campanian stage (around 83.6–72.1 million years ago), and the possible earliest members like Portugalosuchus are from the Cenomanian
Crocodylia — The entry claims 'The possible earliest-known members may be Portugalosuchus and Zholsuchus from the Cenomanian-Turonian stages.' Zholsuchus is a genus of crocodylomorph from the Late Jurassic of Kazakhstan, not from the Cenomanian-Turonian, and is not conside
Deinosuchus — The 'DID YOU KNOW' section incorrectly states Emmons thought the teeth belonged to a crocodilian reptile; Polyptychodon was then considered a pliosaur, not a crocodilian.
Deinosuchus — The claim that a 2025 study suggested Deinosuchus may not be a true crocodilian but a derived non-crocodilian eusuchian is an invented claim, as no such widely-accepted study has been published.
Dimorphodon — The entry incorrectly states that the species D. weintraubi was named in 1998 from a partial skeleton found in Mexico and later studies considered it not closely related to Dimorphodon macronyx, but it fails to note that the species was later reclassified as a
Dinosaur — The entry states dinosaurs first appeared 'early in the Triassic period', but the widely accepted fossil evidence indicates they first appeared in the Middle to Late Triassic (around 230–240 million years ago), not the early Triassic.
Dinosaur — The claim that 'all dinosaurs had erect legs similar to birds and many mammals' is an overgeneralization; while most dinosaurs had erect limbs, some early dinosaurs and close relatives had semi-erect or more sprawling postures, and the statement as written imp
Eoraptor — The entry states Eoraptor belongs to the early sauropodomorph group, but Eoraptor is currently classified as a basal saurischian, not a sauropodomorph.
Eoraptor — The entry says 'It ranks among the earliest known dinosaurs and early sauropodomorphs', which is contradictory because if it is not a sauropodomorph, it cannot be an 'early sauropodomorph'.
Feathered dinosaur — The entry states that the earliest known evidence of possible feather impressions is in the 195–199 million year old Portland Formation, but the Portland Formation is approximately 150–145 million years old, not 195–199 million years old; the 195–199 million y
