Factual Accuracy edit

The reasons given for a factual inaccuracy can be found when presiing the edit button. For non-editing purposes I am listing the reasons here (for making it easier to view), I am not the editor who added the factual inaccuracy just making it easier for others to view: the author data makes no sense. 1. what was the species placed here by Bain in 1856 (a genus cannot be empty when established)? 2. If greyii and prognathus are invalid (PaleoDB says otherwise), why do they not have priority over bainii?

In response to this: 1. a genus when being described can be empty in some circumstances (I have found empty genera before they mostly are because a species hasn't been described or placed in them yet and are notated [Genus name] sp. when I have seen them and normally last a couple of years after the first description).
Onto number 2; nowhere in the article does it mention that O. greyii and O. prognathus are invalid if you mean that why aren't either of them the type species instead of O. bainii then that could be due to the fact that O. prognathus was not described until the same paper or after O. bainii and O. greyii could have been reclassified as a species of Oudenodon after O. bainii's description or it could be an exceptional circumstance where the type species is not the first species named due to O. bainii being better preserved or a better representative of the genus (this rarely happens but it can and does happen).
