Spinosaurus (/ ˌ s p aɪ n ə ˈ s ɔːr ə s /; lit. ' spine lizard ') is a genus of spinosaurid dinosaur that lived in what now is North Africa during the Cenomanian stage of the Late Cretaceous period, about 100 to 94 million years ago.
Oxalaia (in reference to the African deity Oxalá) is a controversial genus of spinosaurid dinosaur that lived in what is now the Northeast Region of Brazil during the Cenomanian stage of the Late Cretaceous period, sometime between 100.5 and 93.9 million years ago.
In 2012, French palaeontologist Ronan Allain and colleagues described a partial skeleton from the Grès supérieurs Formation of Laos, and used it to name the new spinosaurid genus and species Ichthyovenator laosensis. They considered it the first definitive evidence of spinosaurids in Asia, in light of the debated identity of Siamosaurus and "S."
Like other spinosaurids, it likely had a diet of fish,such as eels, rays and smaller aquatic animals. Some palaeontologists consider the genus to be an African species of the European spinosaurid Baryonyx, B. tenerensis.

Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
