in contrast to the more heavily built tyrannosaurids that relied on brute strength

Paleobiological scenarios have been suggested where Pliosaurus funkei ambushed these plesiosaurs as they navigated shallow coastal waters

Recent studies of dental microwear and cranial morphology support a primarily piscivorous diet

The taphonomic study of the fossil remains has revealed direct evidence of cannibalism within the species: some Majungasaurus bones show tooth marks that match in size and morphology with those of this same taxon

Ichthyovenator laosensis Arsinoitherium in contrast to the moreIchthyovenator laosensis was a spinosaurid theropod dinosaur that lived during the Early Cretaceous , approximately 125 to 113 million years ago, in what is now Laos, Southeast Asia. It was discovered in the Grs Suprieurs Formation, a fossil rich site that has provided important data on the Cretaceous fauna of that region. This theropod belonged to the spinosaurid group, known for its semi aquatic adaptations and piscivorous diet. Its size has been
