Iguanodon

Iguanodon was one of the most famous dinosaurs that were common in the North-East Thailand 100 million years ago. It was one of the dinosaurs that were discovered in 1822 in England.

In 1822, an English woman named Mrs.Mantell was traveled back to her home; she noticed a strange fossilized tooth was sticking out of gravel near a house which was not far away from her home. She gave the unknown tooth to Dr. Mantell, her husband, to study what creature was from. Dr.Mantell went to a British Museum and saw that this tooth was familiar to the modern day iguana’s tooth. Therefore, the name Iguanodon was given, which mean “Iguana’s tooth”. Iguanodon was mostly common in the Early Cretaceous period throughout Europe, North America, and in Mongolia.

A group of scientist had discovered a various fossils of two Iguanodon in Nakhon Ratchasima (Khorat) province which was a proof that Iguanodon also had lived in Thailand 100 million years ago. In the Early Cretaceous, Iguanodon had shared it’s habitat to Psittacosaurus a ceratapsian and Phuwiangosaurus a sourwood which was also herbivores, and they lived in the same era. This made Iguanodon one of the most unique dinosaurs that Thailand ever had discovered.

Isanosaurus Attavipachi

Isanosaurus was named after the Isan region of North-East Thailand. It was still considered by scientist that it was a primative sauropod to had ruled the Late Trassic.

The most unique about Isanosaurus that it was mixed of sauropod and prosauropod habits. For example, it could walk on four legs like most sauropod, but it had claws in front feets so that it could stand on it's two back legs like most prosauropods could. This dinosaur was only about 40ft(12.2m) and most of it's fossils are founded in most North-Eastern provinces of Thailand.

This herbavore lived mostly in both forest and swamps. Like the Sauropod, this dinosaurs traveled in large heards so they could protect their youngs from predators. Isanosaurus, unlike other dinosaurs, were discovered in Thailand, this kind of dinosaur was the oldest sauropod that ever had ruled in the Late Trassic.

Siamosaurus Suteethorni

Siamosaurus was another carnivore to ruled the North-East Thailand 100 million years ago along with Siamotyrannus Isanesis. Siamosaurus was one of Spinosaurus relative that has the same crocodile head like Siamosaurus.

Siamosaurus' food were fishes in the large lakes of the Early Cretacous when Thailand was covered by a inland sea. Like Spinosaurus, Siamosaurus also eat the other dinosaurs which also used to live around the same era. Scientist is trying to find out if Siamosaurus had a sail since it also had a same unique habits like it's relative. But unlike it's relative, Siamosaurus was only 30ft(9.1m), it taller than Siamotyrannus which was a rival for food in that era. Most of this dinosaurs' fossils had been found mostly in North-East of Thailand which made a unique dinosaur for the country.

Phuwiangosaurus Sirindhornae

Phuwiangosaurus was one one of the giant sauropod to had ruled Thailand North-East 110 million years ago.

Phuwiangosaurus was one of the titanosaur that had ruled the Early Cretacous period. This sauropod was the first dinosaur to be ever to be discover in Thailand. It was first discovered by a team of geologist that found a fossil near a dried up stream called Huay Pratu Tee Mah in Khon Kaen province in 1981. This was a great discovery since Laos had been discovering it own dinosaurs so it was time for Thailand to have it's own.

While scientist were digging, Princess Chakri Sirindhornae came and see the discovery the first dinosaur. So the scientist gave the name Phuwiangosaurus Sirindhornae to honor the princess and the Charkri Dynasty. Phuwiangosaurus use to feed on tall trees that grows variously in the Creatacous Period. During that era there were various dinosaur like the unname sauropod that is still being studying, Iguanodon, Psittasaurus, Gallimimus, and Siamosaurus. Phuwiangosaurus only has a enemy which was Siamotyrannus that also ruled the same era. This made Phuwiangosaurus one of the giant titanosaur to ever had ruled Indochina.
