Not to be pedantic, but _Monjurosuchus_ is a monjurosuchid choristodere, not a 
champsosaur (=  champsosaurid choristodere).

Monjurosuchids are the baby-caiman mimics, hyphalosaurids are the 
pachypleurosaur-wannabes, and neochoristoderes (champsosaurids and
simoedosaurids) are the gator- and gavial-like ones.
