Earlier here and here we looked at the rare and typically incomplete manus of several basal crocs. With the manus pattern established another look at the manus of SMNS 12352 (Fig. 1) is needed. Sereno and Wild (1992) interpreted the identity of the metacarpals 5-3 aligned. In the new interpretation matching other basal crocs, metacarpals 1-3 were aligned in the basic pattern with metacarpal 5 shorter than the others by half. I’m assuming here that there’s not much else of metacarpal 5 missing behind metacarpal 4.
That also changes the identification of the wrist elements, the ulnare and radiale.
