“…Descriptive terminology used here follows the IAWA list of microscopic features for softwood identification (Baas et al, 2004), with the addition of terms defined in Philippe and Bamford (2008), seriation and contiguity indices proposed by Pujana et al (2016). Pit counting method follows suggestions made by Philippe et al (2013). The palynological samples were treated following standard techniques for extraction and Figure 1.…”

The first fossil remains of vertebrates, invertebrates, plants and palynomorphs of the Chorrillo Formation (Austral Basin), about 30km to the SW of the town of El Calafate (Province of Santa Cruz), are described. Fossils include the elasmarian (basal Iguanodontia) Isasicursor santacrucensis gen. et sp. nov., the large titanosaur Nullotitan glaciaris gen. et sp. nov., both large and small Megaraptoridae indet., and fragments of sauropod and theropod eggshells. The list of vertebrates is also composed by the Neognathae Kookne yeutensis gen. et sp. nov., two isolated caudal vertebrae of Mammalia indet., and isolated teeth of a large mosasaur. Remains of fishes, anurans, turtles, and snakes are represented by fragmentary material of low taxonomical value, with the exception of remains belonging to Calyptocephalellidae. On the other hand, a remarkable diversity of terrestrial and freshwater gastropods has been documented, as well as fossil woods and palinological assemblages. The Chorrillo Formation continues south, in the Las Chinas River valley, southern Chile, where it is called Dorotea Formation. Both units share in their lower two thirds abundant materials of titanosaurs, whose remains cease to appear in the upper third, registering only elasmarians (Chorrillo Formation) and hadrosaurs (Dorotea Formation). Above both units there are levels with remains of invertebrates and marine reptiles. It is striking that the dinosaurs of the lower two thirds of the Chorrillo and Dorotea formations are represented by large basal titanosaurs and Megaraptoridae coelurosaurs, being the Saltasaurinae and Aeolosaurinae sauropods and Abelisauridae theropods totally absent. In contrast, these taxa are dominant components in sedimentary units of central and northern Patagonia (e.g., Allen, Los Alamitos, La Colonia formations). Such differences could reflect, in part, a greater antiquity (i.e., late Campanian-early Maastrichtian) for the Chorrillo fossils, or, more probably, different environmental conditions. Thus, knowledge of the biota of the southern tip of Patagonia is expanded, particularly those temporarily close to the K-Pg boundary.

“…This author proposed that the horizontal septa derived from globular tyloses. Philippe et al (2013) also mentioned the presence of septa-like structures in several Asian specimens related to Xenoxylon, but they considered that their origin is uncertain and without taxonomic value. Feng et al (2015) proposed that septa-like structures, when not related to ray cells, may likely represent host cell reactions to fungal attacks or the remains of metabolic products of fungal enzymatic activity.…”

“…It usually occurs north of 45°, but there are some exotic data from continental Mesozoic redbeds in South-East Asia (Boureau 1950, Vozenin-Serra & Privé-Gill, 1991Boonchai et al, 2017). These Xenoxylon occurences are questionning as the genus is supposedly an indicator of mid-to high palaeolatitudes and cool or wet climates (Philippe et al, 2013;Oh et al, 2015). Frustratingly none of the above mentionned southeast Asia Xenoxylon fossils were found in-situ, except for the Vietnamese data, the age of which has been considered dubious (Boureau, 1950).…”

The fossil wood genus Xenoxylon is reported in-situ for the first time in the Indosinian terrane, from the Mesozoic continental redbeds of the Phu Kradung Formation (Khorat Group). Palinspatic recontruction, palaeobiogeography and correlation with other occurences of the genus, in southern China as well as in Vietnam, suggest a middle Jurassic age for the Phu Kradung Formation level yielding the fossil wood. As the dating of this formation is still controversial, our data is an important step towards a better understanding of southeast Asia Mesozoic continental redbeds geological history, palaeoecology and significance for the evolution of the vertebrates.
