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.
Mallon and Anderson postulated that Ankylosaurs and Ceratopsids may have partitioned the herb layer in the Dinosaur Park Formation, or that Ceratopsid feeding height was slightly higher. [21] As well as suggesting that the Ornithopods might have made room for the passing Ceratopsid herds by rising up to avoid ecological competition.
Scientists say this difference in feeding mechanisms ‘set them up to dominate life on land for millions of years to come’.
