Note:
Brochu (2004) suggested that Thecachampsoides minor (Marsh) and Sphenosaurus clavirostris Morton are actually a cospesific and the correct binomen should Thecachampsoides clavirostris (Morton). However he didn't formalize this chance yet, but continued to use binomen Thecachampsoides minor (Marsh).
Delfino et al. (2005) synonymized Eosuchus Dollo, 1907 and Thecachampsoides Norell & Storrs, 1986, this synonymizing was done based on unpublished work by Brochu. (Delfino, pers. comm.)
Brochu's article formally synonymizing Thecachampsoides with Eosuchusappeared in “Journal of Paleontology’ on spring 2006. For the taxonomic stability, Thecachampsoides clavirostris (Morton) was sunk under binomen Eosuchus minor (March) and was considered as invalid senior synonym by Brochu.
