Fascinating stuff, thanks for sharing the paper.

In light of the recent description of several archosaurs from the Menefee Formation as distinct genera (Dynamoterror, Invictarx, Menefeeceratops, Ornatops), it is highly probable that the material from the Menefee Formation assigned to Deinosuchus could be described as a new genus and species someday when more complete material from this unit is unearthed. There is one extinct neosuchian species described from the Menefee Formation, Brachychampsa sealeyi.
