  Poposauridae - Medbib.com, the modern encyclopedia
The Poposauridae are a family of large (around 2.5 to 5 meters long) carnivorous archosaurs which lived alongside dinosaurs during the Late Triassic.
Originally believed to be theropod dinosaurs (they mirrored the theropods in a number of respects, such as features of the skull), cladistic analysis has shown them to be related to crocodiles.
Despite the genus Postosuchus appearing in the documentary series Walking With Dinosaurs, the group is still poorly known, although it is thought that recent description and discoveries of genera such as Sillosuchus and Shuvosaurus will improve our understanding of these animals and their phylogenetic relationships within the Crurotarsi.

First, _Bromsgroveia_ is a Poposaurid and belongs in the family Poposauridae Nopcsa, 1928.
The problem is when Teratosaurus was in the family Poposauridae, the family Teratosauridae COPE 1871 had priority, but since Teratosaurus is now in Rauisuchidae the family Teratosauridae has priority.
Now if you want to be totally correct (as far as I understand it) the family Rauisuchidae is sunk into the Teratosauridae.
