Reptilia | |
Brachydectes major n. gen. n. sp.

Nannosuchus gracilidens n. gen. n. sp., Goniopholis tenuidens n. sp.
Nannosuchus gracilidens n. gen. n. sp. Owen 1879 crocodilian BMNH 48217 (complete skull) and BMNH 48301 (partial mandible) - syntypes. Unlikely that the two come from the same individual based on size (Salisbury 2002); referred material - BMNH 48303 (isolated postcranial elements) - cannot be referred to Nannosuchus (Salisbury 2002)

"Theriosuchus pusillus n. gen. n. sp." = Theriosuchus pusillus, "Brachydectes minor n. sp." = Theriosuchus pusillus
"Theriosuchus pusillus n. gen. n. sp." = Theriosuchus pusillus Owen 1878 crocodilian BMNH 48330 (complete skull and mandible) and BMNH 48216 (partially articulated skeleton) - syntypes (see Salisbury 2002)
"Brachydectes minor n. sp." = Theriosuchus pusillus Owen 1878 crocodilian BMNH 48328 (left mandibular ramus)
