Paleontological remains

[edit]

Chalawan, an extinct genus of crocodylin, is known solely from its holotype collected in the early-1980s from a road-cut near the town of Nong Bua Lam Phu, in the upper part of the Phu Kradung Formation. This single specimen is the most well preserved vertebrate fossil that has been found from the formation. It contains a single species, Chalawan thailandicus.[7]

History

[edit]

Nong Bua Lam Phu is noted for it being the area where in the 16th century, Naresuan, the king-liberator of Siam, came to learn of the outcome of a war between the Lao and Burmese in the area of Vientiane. This place was formerly a Lao stronghold and named "Nakhon Khuean Khan Kab Kaew Bua Ban" (Thai: นครเขื่อนขันธ์กาบแก้วบัวบาน). During the existence of the Lao Kingdom of Lan Xang (1354–1707), Nong Bua Lam Phu was traditionally given to the crown prince (Uparat) to rule. It was the birthplace of the principal wife of Ong Boun (พระเจ้าศิริบุญสาร), the last independent king of Vientiane.[8] In 1827, Chao Anou of Vientiane designated Phagna Narin to be governor at the onset of the Laotian Rebellion of 1826–1828.

Under Thai rule, the province originally consisted of five amphoe (districts) in Udon Thani province. In 1993 Udon was decentralized and a separate province of Nong Bua Lam Phu was created. It is one of the newest provinces of Thailand, together with Amnat Charoen province, Sa Kaeo province, and Bueng Kan province.

On 6 October 2022, a mass murder occurred at and near a daycare center in Uthai Sawan, a town located in the province. A total of 36 people were killed, and 10 others were injured, before the attacker committed suicide. It was the deadliest mass murder by a single perpetrator in the modern history of Thailand.[9]

Symbols

[edit]

The seal of the province shows King Naresuan in a shrine. This shrine was built to commemorate the visit of King Naresuan to the city of Nong Bua Lam Phu in 1574 when he was gathering troops to fight the Burmese kingdom Toungoo. Behind the shrine is a pond with lotus flowers (Nymphaea lotus), which is the provincial flower. The provincial tree is the Siamese rosewood (Dalbergia cochinchinensis). The edible minnow Henicorhynchus siamensis is the provincial aquatic life.
