     A New Destination for Prehistoric Study

    Verdant forests, crystal clear blue seas, casuarina-lined beaches, colourful coral reefs...these, as most visitors think of, are not all about Thailand. There are a lot more in this country that you haven't discovered.
    If you have known Thailand only through the eyes of travellers, this time you'll know her via palaeontologists' point of view. In this article, we will give brief explanations of the fossils of dinosaurs, orang-utans and the Lepidotes fish which were recently found only in the northeastern part of Thailand.
    The holotype fossils of Phuwiangosaurus sirindhornae from the Phu Wiang pit.
    History of Thai Palaeontology
    Thailand has become significant for palaeontology since the first unearthing of ancient fish fossils in the northern part of Thailand in 1916. But it was not until 1976 that the earliest dinosaurs' fossils were discovered in Phu Wiang county, Khon Kaen province in the northeastern part. Even though the evidences collected at that time could not pinpoint to which species the fossils belonged to, they indicated that the fossils were of herbivorous sauropods. Soon after that, around 1979, a palaeontological team in the Northeast reported on the uncovered fossils of dinosaurs and croco-
    diles in scattered places. However, the remarkable discovery that marked as a milestone in the development of Thai palaeontology was in 1981, also in Phu Wiang county, in which two femora of dinosaurs were uncovered.

    Phuwiangosaurus sirindhornae.
    Moreover, the expedition team found the dentition of dinosaurs and fossils of ancient animals such as crocodiles, fish and turtles. In 1982, the same team discovered a piece of dinosaur's rib in the rock layer, and when they continued digging up, several fragments of dinosaur fossils were revealed.
    Dinosaurs' fossils found in Thailand up till now dated from 225 to 100 million years ago. For example, the ischium of a herbivorous pro-sauropod discovered in 1992 in Nam Nao county, Phetchabun province, was of the Nam Phong Formation of the late Triassic (210 million years). These fossils are the oldest ones dug up in Southeast Asia, and this uncovering of pro-sauropod is the first in this region. When compared with the prosauropods from sites out of Asia, these fossils found in Thailand show a larger structure with a length of eight metres.

    prosauropod discovered in 1992.
    The earliest sauropod named Isanosaurus attavipachi was discovered in the Nam Phong Formation of the Triassic. The femora and other remains show characteristics of the four feet walking herbivore with a long neck and long tail. Its body length measures 16 metres.
    Phuwiangosaurus sirindhornae,
    a new species of the sauropods
    found only in Thailand.
    This discovery proves that the sauropods existed before the Jurassic (190 million years) and that the present site of Thailand has long been connected to the Asian Continent.

    7-9 million years
    Many more fossils have been dug up so far. To name the most significant, the discovery of Phuwiangosaurus sirindhornae is described here in brief.

    As mentioned above, in 1982, heaps of dinosaur fossils were uncovered by a palaeontologist team in Phu Wiang county. That was the first time that they found several parts of a dinosaur in a pit.
    The characteristics show that it was a new species of the gigantic herbivorous sauropods that walked on four feet and had the long neck and tail. By royal permission, it was named after HRH Princess Maha Chakri Sirindhorn, a princess full of enthusiasm for knowledge, particularly in history, art and culture.
    The Recent Discoveries of Fossils
    Lately, there have been reports on the discovery of a new species of orang-utan from the Late Miocene in Thailand, Khoratpithecus piriyai gen. et sp. Nov. It was named in honour of Mr Piriya Vachajitapan who found the remains in a sand pit in Chaloem Phrakiat county, Nakhon Ratchasima province in the northeastern Thailand and who handed in specimens to the Department of Mineral Resources in August 2002. The fossils discovered are the lower jaw of a new hominoid from the Late Miocene (7-9 million years) with eleven teeth remaining intact.

    The characteristics indicate that they share the unique features with orang-utans more than other known Miocene hominoids. Even though the fossils of Khoratpithecus piriyai sp. Nov. are similar to Khoratpithecus Chiangmuanensis, they are grouped into a new species due to the absence of anterior digastric muscle impressions. That area had developed to be an organ to make a voice to communicate within the herd.

    So far, there have been no discoveries of apes bearing these characteristics. Thus, this leads to the conclusion that these fossils were the closest known relative of orang-utans. Since the fossil record of the living great apes is poor, the uncovering of these new fossils are vital for an understanding of their origins and evolution.
    In addition, in the same area, fossils of other mammals were found as well, such as four-tusk elephants, ancient rhinoceroses, ancient horses and ancient giraffes, whose age ranges are about 7-9 million years.

    Lately, a new semionotid fish, Lepidotes Buddha butrensis n. sp., has been discovered. These fish fossils were described to be a new species of the late Jurassic, early Cretaceous, the Phu Kradueng Formation. This is because this fish had dorsal ridge scales and more than one suborbital present on the cheeks. These characteristics have not been found in any other fish fossils. The fossils were uncovered on the slope of the Phu Nam Jun hill, Kalasin province, by the abbot of Phutthabut Temple. The name of this fish was derived from that of the temple, which is near the fossils' pit where numerous specimens are housed.
    Palaeontologists at work at the hill of Phu Nam Jun, where the Lepidotes fish fossils were newly discovered in Thailand.
    Semionotids are the fish having a different jaw formation from that of other fish species. They have relatively short separate frontal jaws which enable them to form the mouth into a tube-like shape to suck food from afar. This differed from fish in early eras which could suck only food near their mouths. Moreover, Lepidotes fish possess hard scales which supported the body as the vertebral bone had not yet been fully developed like those of the fish in the Tertiary.
    Fossils of Lepidotes buddhabutrensis n. sp.
    The discovery site is a layer of accumulated sandstone sediment housing more than 100 specimens of fish fossils. Thus, palaeontologists assumed that that area was possibly once a large pond in which various kinds of fish inhabited, that in some intervals prolonged droughts occurred, draining the pond and killing the fish, and that as a result, the fish bodies piled up in rock layers and became fossils. The hill of Phu Nam Jun is considered as the earliest site possessing the perfect-conditioned fish fossils in the largest number in Thailand.

    All these discoveries are evidently crucial for palaeontological study in Thailand. At present, Thai palaeontologists, in cooperation with a French palaeontological team are devoting themselves to further researches and expeditions.

    Dinosaur Museums
    If you are one of the growing number of dinosaur enthusiasts, you are recommended to visit either of the following museums:
    HRH Princess Maha Chakri Sirindhorn visiting a dinosaur discovery site at Phu Kum Khao, Kalasin province.
    1. The Phu Kum Khao Dinosaur Museum, near Sakkawan Temple, Sahatsakhan county in Kalasin province (519 km Northeast of Bangkok). To reach there, drive from Kalasin town along Highway 227. Around three kilometres before arriving in Sahatsakhan county, turn right towards Sakkawan Temple. Then drive ahead for a further 800 m.

    This 500-rai (200 acres) place features stories of prehistoric creatures before the dinosaur era, fundamental geological studies, dinosaur lives, etc. The entrance to this museum was designed after that of the Egyptian Abu Simbel. The interior atmosphere gives you the mysterious feeling of being in the Pyramid of Gizeh. Outside the museum, plants and trees of the Jurassic are grown surrounding the building. There are a large pond and huge dinosaur replicas standing there imitating the way they were supposed to be millions of years ago. The museum opens daily from 8:30 to 17:30. Tel: 0 4387 1014.

    2. The Phu Wiang Dinosaur Museum, Phu Wiang county, Khon Kaen province (449 km from Bangkok). To reach there, drive from Khon Kaen town along the Khon Kaen-Chum Phae road. Then turn right onto Highway 2038 to enter Phu Wiang county. Drive a further 12 km to reach tourist service centre. This museum presents the fundamental geological knowledge and details of the discoveries and researches of the local sites and of the neighbouring areas. It opens daily from 8:30 to 17:00. Tel: 0 4343 8204-6.
