Titanoboa could grow up to 12.8 m (42 ft) long, perhaps even up to 14.3 m (47 ft) long, and weigh around 730–1,135 kg (1,610–2,500 lb). The discovery of Titanoboa cerrejonensis supplanted the previous record holder, Gigantophis garstini, which is known from the Eocene of Egypt.
• 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.
In dinosaurs, the anatomy of the braincase is conservative, but for this reason can be used to infer relationships of a group when other skeletal features underwent changes so profound that their origins can no longer be traced. The braincase may also allow for reconstructing the brain and inner ear, with inferences on senses and intelligence. [20]
A diagram showing the estimated lengths of Gigantophis garstini compared to other large snakes.. Jason Head, of the Smithsonian Institution in Washington, DC, has compared fossil Gigantophis garstini vertebrae to those of the largest modern snakes, and concluded that the extinct snake could grow from 9.3 to 10.7 m (30.5 to 35.1 ft) in length.
The genus Varanus is believed to have originated in South Asia in the Miocene epoch around 20 million years ago, and the anatomy of its earliest members are thought to resemble today's Indian group, which includes modern Yellow monitors (subgenus Empagusia) like the Bengal monitor.
The skull of Python reticulatus.. The skull of a snake is a very complex structure, with numerous joints to allow the snake to swallow prey far larger than its head.. The typical snake skull has a solidly ossified braincase, with the separate frontal bones and the united parietal bones extending downward to the basisphenoid, which is large and extends forward into a rostrum extending to the ...
Titanoboa: Monster Snake is a 2012 documentary film produced by the Smithsonian Institution.The documentary treats Titanoboa, the largest snake ever found.Fossils of the snake were uncovered from the Cerrejón Formation at Cerrejón, the tenth biggest coal mine in the world in the Cesar-Ranchería Basin of La Guajira, northern Colombia, covering an area larger than Washington, D.C. [1] The ...
Diagram of a prawn, with the carapace highlighted in red. A carapace is a dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron.
