Titanophoneus potens

Titanophoneus potens ("Potent titanic murderer") was a carnivorous Therapsid of the Dinocephalia group related to the Estemmenosuchidae but living 5 million years later than Estemmenosuchus uralensis and Estemmenosuchus mirabilis during the Late Permian. Remains of this animal have been found at Isheevo in Russia.
These very remains you can see here on this photo I have made in the Moscow Paleontological Museum.
