... Cretaceous crocodylomorphs reported from Thailand are restricted for now to certain neosuchians (Buffetaut and Ingavat 1980, 1983, 1984, Lauprasert et al. 2007, 2011, Martin et al. 2014a). SM-2023-1-16 and SM2021-1 are clearly not longirostrine, hence they do not belong to Chalawan thailandicus Martin et al., 2014a or the poorly known eusuchian from Ban Saphan Hin (Kubo et al. 2018). ...

... Currently, the Sao Khua dinosaur assemblage is heavily dominated by a rich array of at least seven tetanuran non-avian theropods including the?metriacanthosaur Siamotyrannus (Buffetaut et al., 1996), spinosaurid "Siamosaurus" (Buffetaut and Ingavat, 1986;Amiot et al., 2009), a possible second spinosaurid taxon "Phu Wiang spinosaurid B" ( [Samathi et al., 2021]), megaraptoran Phuwiangvenator (Samathi et al., 2019a), and coelurosaurian Vayuraptor (Samathi et al., 2019a(Samathi et al., , 2019b, ornithomimid Kinnareemimus , an unnamed carcharodontosaurid from Phu Wang (Buffetaut and Suteethorn, 2012), and an indet. Tetanuran (Buffetaut and Ingavat, 1984, formerly considered a compsognathid, see Samathi et al., 2019b), and at least two sauropods, including the somphospondylan Phuwiangosaurus (Martin et al., 1994), and an unnamed taxon (Buffetaut and Suteethorn, 1999). A late Valanginian-early Hauterivian age for Phuwiangosaurus does not result in a range extension for Somphospondyli; however, it does increase the significance of this taxon for understanding the early evolutionary history and biogeographic distribution of the clade. ...

... Dinosaur footprints at the Phu Luang site were first reported by Buffetaut et al. (1985a); this pioneering work was followed by many studies of dinosaur ichnology in northeastern Thailand (e.g. Buffetaut et al., 1985bBuffetaut et al., , 1997Buffetaut et al., , 2005Polahan and Daorerk, 1993;Le Loeuff et al., 2002, 2003, 2007, 2008Lockley et al., 2002Lockley et al., , 2006bLockley et al., , 2009. ...

... The Sao Khua Formation is one of the few well-studied, dinosaurbearing formations in Southeastern Asia and represents a key data point in the region. When the first isolated dinosaur remains were discovered in the Sao Khua Formation, they were considered Middle to Late Jurassic in age, in line with previous biostratigraphic estimates ( Ward and Bunnag, 1964;Ingavat and Taquet, 1978;Buffetaut and Ingavat, 1983; see review in Buffetaut and Suteethorn, 1999). However, with further study and the recovery of better macrovertebrate fossils, the age of the Sao Khua Formation was understood to be younger. ...

... Moreover, the reddish-brown stratum of the KKF (sandstones, siltstones, mudstones, and conglomerates, interbedded with gypsum lenses and calcrete nodules) was deposited in meandering rivers, in a semi-arid to an arid environment [30], during the early-middle Cretaceous (dated by freshwater bivalves [32]). The different lithologic and depositional aspects found in previous works [10,12] are of interest to the current work for identifying and classifying the petrographical and geochemical characteristics of the Mesozoic sandstones in detail. ...

... There are no erinaceids in common between the Mae Moh and Li Mae Long faunas of Thailand. Li Mae Long was described as an early Miocene locality by Mein and Ginsburg (1997), but some studies suggest a middle Miocene age (Jaeger et al., 1985;Ducrocq et al., 1994) which is especially supported by the strong similarities between Li Mae Long and Mae Moh rodents (Chaimanee et al., 2007). Zijlstra and Flynn (2015) have noted that a few unidentified erinaceids from the middle Miocene Chinji Formation, dated between 13.4 and 12.3 Ma, showed affinities with the erinaceids of Li Mae Long. ...

... Furthermore, owing to redeposition from erosional continental sediments, the KeAr age can only provide the lowermost depositional age for the clay layer. However, the above chronological results are quite consistent with the postulated Aptian-Albian ages of the fauna assemblages (e.g., selachians, holosteans and dinosaurs) for the underlying Khok Kruat Formation (Buffetaut and Ingavat, 1986). Therefore, at least the age of the Nong Boua Formation can be constrained to be around the late Early Cretaceous to Late Cretaceous in age. ...

... Their resistance to weathering and chemical alteration (Argast et al., 1987) make them good proxies for paleoenvironmental and paleoecological reconstructions and can provide essential information on species diversity in fossil ecosystems, especially where other skeletal remains are rare or absent . If the taxonomic affinity of isolated theropod dental material was explored through comparative anatomy during the 19th and 20th centuries (e.g., Ameghino, 1899;Antunes & Sigogneau-Russell, 1991;Buffetaut & Ingavat, 1986;Currie et al., 1990;del Corro, 1966;Depéret, 1896;Depéret & Savornin, 1925;Hendrickx et al., 2015a;Hislop, 1861;Leidy, 1856;Lydekker, 1890;Owen, 1854; O. W. M. Rauhut & Kriwet, 1994;Rauhut & Werner, 1995;Zinke, 1998;Zinke & Rauhut, 1994), qualitative and quantitative methods based on computational programs have become the new standard to identifying isolated theropod teeth over the past 20 years. Morphometric analyses conducted on a data set of crown and denticle-based measurement variables taken in a large number of theropod taxa were the first analytical methods performed to classify isolated theropod teeth (Smith et al., 2005). ...

... Pleistocene terrestrial mammal associations are unequally known within this vast territory, which includes the Indian, Indochinese, Sundaic, Philippine, and Wallacean subregions. Nevertheless, Middle and Late Pleistocene mammal associations were discovered in all of these sub-regions, in ancient or newly excavated sites, mostly in caves, such as: -Mogok in Myanmar (Colbert, 1943); -Koloshan, Hoshangtung, Hsingan, Yenchingkuo, Hejiang, Panxian Dadong, and Mulan in South China, (Kahlke, 1961;Colbert and Hooijer, 1953;Zhang et al., 1997;Jin et al., 2009;Zhang et al., 2014); -Tambun, Badak, and Batu in Malaysia (Medway, 1972;Ibrahim et al., 2013);-Punung, Trinil, Sibrambang, Lida Ajer, Niah, Song Terus, and Liang Bua in Indonesia (Badoux, 1959;Medway, 1964;de Vos et al., 1982;de Vos, 1983;van den Bergh et al., 1996van den Bergh et al., , 2009Harrison, 1996;Sé mah et al., 2004); -the Cagayan valley and Callao cave in Philippines (Koenigswald, 1956;Bautista, 1991;Mijares et al., 2010); -Phnom Loang in Cambodia (Beden and Gué rin, 1973); -Tam Hang in Laos (Fromaget, 1936;Bacon et al., 2008aBacon et al., , 2011; -Tham Khuyen, Tham Hai, Lang Trang, Tham Om, Ma U'Oi, and Duoi U'Oi in Vietnam (Olsen and Ciochon, 1990;de Vos and Long, 1993;Ciochon et al., 1996;Bacon et al., 2004Bacon et al., , 2006Bacon et al., , 2008b; -Tham Wiman Nakin, Tham Prakai Phet, Ban Khok Sung, Ban Tha Chang, Tham Lod rockshelter, and the Cave of the Monk in Thailand (Ginsburg et al., 1982;Tougard, 1998Tougard, , 2001Haines et al., 2004;Shoocongdej, 2006;Zeitoun et al., 2005Zeitoun et al., , 2010Suraprasit et al., 2015). ...
