Embolomeres
Extracted from the Wikipedia article Embolomeri.
Embolomeres were among the earliest large carnivorous tetrapods, with members such as the crocodilian-like Proterogyrinus appearing in the Visean stage of the Carboniferous. They declined in diversity during the Permian period, though at least one representative (Archeria) was common in the Early Permian. Embolomeres went extinct shortly before the end of the Permian.
