... that Irritator is only known from a skull that was badly obscured by plaster which was added by the commercial fossil-collecting fossil-poachers who illegally sold it in hopes of making the fossil look more complete and valuable?
... that rhynchosaurs had unique teeth that were modified into broad tooth plates?
... that a trackway produced by an unknown crocodyliform that measured approximately 12 meters in length was uncovered in the Galve region of Spain?
"It is well known, that on the Ohio, and in many parts of America further north, tusks, grinders, and skeletons of unparalleled magnitude are found in great numbers, some lying on the surface of the earth, and some a little below it ... But to whatever animal we ascribe these remains, it is certain that such a one has existed in America, and that it has been the largest of all terrestrial beings."
The Crurotarsi ("cross-ankles") are a group of archosaurs, whose name was erected as a node-based clade by Paul Sereno in 1991 to supplant the old term, Pseudosuchia. Crurotarsi are by definition the sister group of the Avemetatarsalia (all forms closer to birds than crocodiles). Crurotarsi is one of the two primary daughter clades of the Archosauria. The skull is often massively built, especially in contrast to ornithodires; the snout narrow and sometimes tending to be elongate, the neck is short and strong, and the limb posture ranging from typically reptilian sprawling to dinosaur or mammal-like erect (although this is achieved in a different way to dinosaurs and mammals). The body is often protected by two or more rows of armored plates. Many crurotarsans reached large size: approximately around three meters or more in length.
