The skull material confirmed Titanoboa's initial placement within the subfamily, now also supported by the reduced palatine choanal. The 2013 abstract recovered Titanoboa as closely related to taxa from the Pacific Islands and Madagascar , linking the Old World and New World boids and suggesting that the two lineages diverged by the Paleocene ...
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). [18] Rubidgea atrox is the largest African gorgonopsian, with skull of nearly 45 cm (18 in) long. [19]
Purussaurus is an extinct genus of giant caiman that lived in South America during the Miocene epoch, from the Friasian to the Huayquerian in the SALMA classification. It is known from skull material found in the Brazilian and Peruvian Amazon, Argentina, Colombian Villavieja Formation, Panamanian Culebra Formation, Urumaco and Socorro Formations of northern Venezuela.
Gigantophis is an extinct genus represented by its sole member Gigantophis garstini, a giant snake. [3] Before the Paleocene constrictor genus Titanoboa was described from Colombia in 2009, Gigantophis garstini was regarded as the largest snake ever recorded.
Relative to the entire skull length, the rostrum of Cerrejonisuchus is the shortest of any dyrosaurid. It, along with Chenanisuchus, are the only short-snouted dyrosaurids. The snout of Cerrejonisuchus is narrow and consistent in width from the external nares, or nostril openings, to the orbits, or eye sockets. The margin of the snout, unlike ...
• Titanoboa cerrejonensis is an extinct boid only known from large vertebrae and skull material, but size estimates suggest it is one of the largest snakes known. In 2009, Jason Head and colleagues estimated it at ~12.8 metres (42 ft) (+/-2.18 m) by regression analysis that compared vertebral width against body lengths for extant boine snakes.
A 13,600-year-old mastodon skull was uncovered in an Iowa creek, state officials announced this week. Iowa's Office of the State Archaeologist said in a social media post that archaeologists found ...
