Siamraptor suwati prowls across a fallen log “bridge” overhanging a river in the jungle of Early Cretaceous Southeast Asia between 125 and 113 million years ago. Named for being uncovered in Thailand (once Siam), Siamraptor was not a “raptor” like Velociraptor but rather one of the carcharodontosaurs, the same group of meat-eating dinosaurs as Giganotosaurus and Carcharodontosaurus. Nonetheless, it would have grown significantly smaller than either of those dinosaurs, with its body length being estimated at twenty-six feet (or eight meters).
