Dinosaurs.

Phuwiangosaurus sirindhornae (meaning "Phu Wiang lizard") is the name given to a genus of dinosaur from the Early Cretaceous. It was a titanosaur which lived in Thailand. The type species, P. sirindhornae, was described by Martin, Buffetaut, and Suteethorn in 1994, it was named to honour Princess Maha Chakri Sirindhorn of Thailand on her interested on geology and palaeontology of Thailand. It was around 90 feet long.
This new genus is very different from the sauropods from the upper Jurassic of China. Abundant remains of juveniles, attributed to Phuwiangosaurus sirindhornae, provide new data on babies sauropodes, little known until now.

Siamotyrannus Isanensis (meaning "Siamese Tyrant") is a genus of theropod dinosaur from the early Cretaceous (Aptian-Albian). It is known from a partial skeleton which includes part of the pelvis, the sacrum, and a number of vertebrae. The fossils were found in 1993 by Somchai Traimwichanon in the Sao Khua Formation of northeastern Thailand. As evidenced by its name, it was originally thought to be a tyrannosauroid, though due to lacking some of the primary tyrannosauroid synapomorphies that define the clade, its position here is not certain. Some analyses have categorized Siamotyrannus as a primitive carnosaur rather than a basal tyrannosauroid, and it has several features that may determine it to be an allosaurid or a sinraptorid. Little is known of the appearance of the animal, though the known elements suggest it was approximately 6.5 meters long.

Siamosaurus Suteethorni (meaning "Siamese lizard") is a genus of theropod dinosaur from Early Cretaceous Thailand. The size of the animal is unknown, but it may have reached a length of about 9.1 meters (30 ft). The type species, Siamosaurus suteethorni, was formally described by Buffetaut and Ingavat in 1986. There is very little information on this Cretaceous meat-eater, but it is known from teeth that closely resemble those of Spinosaurus; it may have eaten fish.

 Psittacosaurus Sattayaraki (from the Greek for "parrot lizard") is a genus of psittacosaurid ceratopsian dinosaur from the Early Cretaceous Period of what is now Asia, about 130 to 100 million years ago. It is notable for being the most species-rich dinosaur genus. Nine to eleven species are recognized from fossils found in different regions of modern-day China, Mongolia and Russia, with a possible additional species from Thailand.
