A close rival in size to those snakes is palaeophiid marine snake Palaeophis colossaeus, which may have been around 9 m (30 ft) in length [254] [256] [257] or even up to 12.3 m (40 ft). [258] Another known very large fossil snake is Gigantophis garstini , estimated at 9.3–10.7 m (31–35 ft) in length, [ 259 ] [ 260 ] although later study ...
Titanoboa (/ ˌtaɪtənəˈboʊə /; lit. 'titanic boa') is an extinct genus of giant boid (the family that includes all boas and anacondas) snake that lived during the middle and late Paleocene. Titanoboa was first discovered in the early 2000s by the Smithsonian Tropical Research Institute who, along with students from the University of ...
Vasuki is an extinct genus of madtsoiid snake from the Middle Eocene Naredi Formation of India. The genus contains a single species, V. indicus, known from several vertebrae. Vasuki has an estimated body length between 10.9–15.2 m (36–50 ft), making it the largest known madtsoiid. The upper bounds of the length estimates would make Vasuki ...
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.
Madtsoiidae. Madtsoiidae is an extinct family of mostly Gondwanan snakes with a fossil record extending from early Cenomanian (Upper Cretaceous) to late Pleistocene strata located in South America, Africa, India, Australia and Southern Europe. Madtsoiidae include very primitive snakes, which like extant boas and pythons would likely dispatch ...
The recent fossil record of Eunectes is relatively sparse compared to other vertebrates and other genera of snakes. The fossil record of this group is effected by an artifact called the Pull of the Recent. [6] Fossils of recent ancestors are not known, so the living species 'pull' the historical range of the genus to the present.
Green anaconda. The green anaconda (Eunectes murinus), also known as the giant anaconda, emerald anaconda, common anaconda, common water boa, or southern green anaconda, is a semi-aquatic boa species found in South America and the Caribbean island of Trinidad. It is the largest, heaviest, and second longest snake in the world, after the ...
The longest venomous snake, with a length up to 18.5–18.8 ft (5.6–5.7 m), is the king cobra, [1] while contesters for the heaviest title include the Gaboon viper and the Eastern diamondback rattlesnake. All of these three species reach a maximum mass in the range of 6–20 kg (13–44 lb).
