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.
The largest known prehistoric snake is Titanoboa cerrejonensis, estimated at 12.8 m (42 ft) or even 14.3 m (47 ft) [266] in length and 1,135 kg (2,502 lb) in weight, [267] and madtsoiid Vasuki indicus which is estimated to reach between 11–15 m (36–49 ft). [268]
In 2020, Cooper and his colleagues reconstructed a 2D model of megalodon based on the dimensions of all the extant lamnid sharks and suggested that a 16 meters (52 ft) long megalodon would have had a 4.65 m (15.3 ft) long head, 1.41 m (4 ft 8 in) tall gill slits, a 1.62 m (5 ft 4 in) tall dorsal fin, 3.08 m (10 ft 1 in) long pectoral fins, and ...
Compared to odontocetes, the efficiency of baleen whales' filter feeding scales more favorably with increasing size when planktonic food is dense, making larger sizes more advantageous. The lunge feeding technique of rorquals appears to be more energy efficient than the ram feeding of balaenid whales; the latter technique is used with less ...
For the first size comparison, the background also shouldn't be gray, O. citonensis is still only ~3 meters, and it still looks like a tiny O. orcinus clone instead of reflecting the proportions mentioned above. --Slate Weasel (talk | contribs) 12:43, 28 December 2018 (UTC)
For comparison, the average global temperature for the period between 1951 and 1980 was 14 °C (57 °F). [76] The latitudinal temperature gradient was approximately 0.24 °C per degree of latitude. [77] The poles also lacked ice caps, [78] though some alpine glaciation did occur in the Transantarctic Mountains. [79]
Gigantopithecus (/ d ʒ aɪ ˌ ɡ æ n t oʊ p ɪ ˈ θ i k ə s, ˈ p ɪ θ ɪ k ə s, d ʒ ɪ-/ jy-gan-toh-pi-thee-kuhs, pith-i-kuhs, ji-; [2] lit. ' giant ape ') is an extinct genus of ape that lived in southern China from 2 million to approximately 300,000 to 200,000 years ago during the Early to Middle Pleistocene, represented by one species, Gigantopithecus blacki.

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.
