The known adult of Repenomamus giganticus reached a total length of around 1 m (3 ft 3 in) and an estimated mass of 12–14 kg (26–31 lb). The largest gobiconodont and the largest well-known Mesozoic mammal was Repenomamus. įurther information: Mammal Non-therian mammals Gobiconodonts (Gobiconodonta) A reconstruction of Repenomamus The largest known docodont was Castorocauda, almost 50 cm (20 in) in length.It is known by a right lower molariform 3.3 mm (0.13 in) in length, which is bigger than molariforms of all other morganucodontans. Paceyodon davidi was the largest of morganucodontans, cynodonts close to mammals.The largest known non-mammalian cynodont is Scalenodontoides, a traversodontid, which had a maximum skull length of approximately 61.7 centimetres (24.3 in) based on a fragmentary specimen.The largest of therocephalians is Scymnosaurus, which reached a size of the modern hyena. Other large gorgonopsians include Dinogorgon with skull of ~40 cm (16 in) long, Leontosaurus with skull of almost 40 cm (16 in) long, and Sycosaurus with skull of ~38 cm (15 in) long. Rubidgea atrox is the largest African gorgonopsian, with skull of nearly 45 cm (18 in) long. Inostrancevia latifrons is the largest known gorgonopsian, with a skull length of more than 60 cm (24 in), a total length approaching 3.5 m (11 ft) and a mass of 300 kg (660 lb). Gorgonopsians (Gorgonopsia) Photo-reconstruction of Inostrancevia Adult specimens could reach 6 m (20 ft) in length and over 600 kg (1,300 lb) in weight. Another enormous dinocephalian was the Late Permian Eotitanosuchus (a possible synonym to Biarmosuchus ). Fully grown Titanophoneus from the same family Anteosauridae likely had a skull of 1 m (3.3 ft) long. Dinocephalians (Dinocephalia) Anteosaurus overviewing the landscapeĪmong the largest carnivorous non-mammalian synapsids was the dinocephalian Anteosaurus, which was 5–6 m (16–20 ft) long, and weighed 500–600 kg (1,100–1,300 lb). The plant-eating dicynodont Lisowicia bojani is the largest-known of all non-mammalian synapsids, at about 4.5 m (15 ft) long, 2.6 m (8 ft 6 in) tall, and 9,000 kg (20,000 lb) in body mass. Therapsids (Therapsida) Anomodonts (Anomodontia) Lisowicia compared to a human The Middle Permian Tappenosaurus was estimated at 5.5 m (18 ft) in length, nearly as large as the largest dinocephalians. The largest members of the genus Dimetrodon were also the world's first fully terrestrial apex predators. The biggest carnivorous synapsid of Early Permian was Dimetrodon, which could reach 4.6 m (15 ft) and 250 kg (550 lb). The largest edaphosaurids were Lupeosaurus at 3 m (9.8 ft) long and Edaphosaurus, which could reach even more than 3 m (9.8 ft) in length. Edaphosaurids (Edaphosauridae) Size comparison of some species of Edaphosaurus Cotylorhynchus hancocki is also large, with an estimated length and weight of at least 6 m (20 ft) and more than 500 kg (1,100 lb). The herbivorous Alierasaurus was the largest caseid and the largest amniote to have lived at the time, with an estimated length around 6–7 m (20–23 ft).
