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 ecological effects of piscivores can extend to other food chains. In a study of cutthroat trout stocking, researchers found that the addition of this piscivore can have noticeable effects on non-aquatic organisms, in this case bats feeding on insects emerging from the water with the trout.

Its position at the top of the food chain [94] probably had a significant impact on the structuring of marine communities. [ 93 ] [ 95 ] Fossil evidence indicates a correlation between megalodon and the emergence and diversification of cetaceans and other marine mammals.
Short-faced bears were among the largest meat-eating mammals that ever lived. When they reared up on their hind legs, they would have been about twice as tall as a full-grown person.
An asteroid struck Earth 66 million years ago, triggering a horrific mass extinction. New research that relied heavily on fossilized feces and vomit - evidence of who is eating what and who is ...

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 believe they may have uncovered the first known incident of a mammal being eaten by a dinosaur. Palaeontologists in the UK have analysed fossil remains from around 120 million years ago ...
