Siamraptor was a meat-eating dinosaur that lived in what is now Thailand, about 121 to 113 million years ago. It was a fast and smart hunter with sharp claws and strong jaws. Scientists think it was one of the earliest big meat-eaters in its family.1 4

Siamraptor had a very light skeleton with lots of air spaces in its skull and backbone, which made it lighter and helped it breathe better.2

Its lower jaw had a deep oval hole and four small openings, which are special features not seen in other allosauroids.2

Siamraptor is the first named carcharodontosaurian dinosaur from Southeast Asia, which helps scientists understand how these dinosaurs spread across the world.1

The fossil bones show that Siamraptor had a huge number of air pockets and holes, a feature called skeletal pneumaticity, which is also seen in some other big meat-eaters.2

Siamraptor lived during the Aptian age, about 121 to 113 million years ago, when Thailand was part of a landmass with different animals than today.1 4

The name Siamraptor honors Suwat Liptapanlop, a supporter of fossil research in Thailand, with the species name 'suwati'.1

Wothetsa nthano zabodza

Nthano: Some people think Siamraptor was a type of raptor like Velociraptor.

Zoona: Siamraptor was not a raptor. It belonged to a group called Carcharodontosauria, which were large meat-eaters, not the small feathered raptors.1

Akukambiranabe: Scientists are still debating exactly how Siamraptor is related to other carcharodontosaurs, because it has some features that are more primitive than later members of the group.2
