where do proterochampsids belong?
Here's what the literature says:
(if I missed any let me know).
Proterochampsidae derived from Erythrosuchidae, outside of Parasuchia + Suchia
Benton and Clark 1988, Benton 1990, Bennett 1996
Proterochampsidae derived from Erythrosuchidae, outside of Euparkeria
Proterochampsidae derived from Euparkeria, outside of Ornithodira + Parasuchia
Proterochampsidae derived from Euparkeria, outside of Ornithodira
Proterochampsidae and Euparkeria are basal to all other traditional
archosauriformes (proterosuchids and erythrosuchids not listed).
Question is: which is correct?
