📖 1. Overview
Inostrancevia alexandri (genus Inostrancevia) was a gorgonopsian (saber-toothed carnivorous therapsid) that lived in Russia during the Late Permian; thanks to its huge size, it is one of the most famous Permian animals. It is the best-known gorgonopsian of the Northern Hemisphere.
🦴 2. Anatomy & Morphology
Gorgonopsians were carnivores with large saber-shaped canine teeth, and this species had a massive build comparable only to Rubidgea of Africa. Rows of large openings in the bones of the palate are a characteristic feature of Russian gorgonopsians.
🔍 3. Fossil Record & Paleoecology
It belonged to the top predator group on land at the time. Beginning in the 1890s, V. P. Amalitzky conducted large-scale excavations at Sokolki along the Northern Dvina River and collected many Late Permian gorgonopsian fossils, and this species was described as a new species in 1922.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
