Non-marine overdue Palaeozoic and Mesozoic formations are common in mainland SE Asia. even if the 1st studies on fossils from a few of these formations have been released as early because the Eighteen Nineties, it is just because 1980 that floras and faunas from the Permian, Triassic, Jurassic and Cretaceous of SE Asia have bought the eye they deserve. Fieldwork in a number of components of Thailand and Laos has printed a succession of fossil assemblages that now permits a reconstruction of the evolution of continental ecosystems in that a part of the realm through the past due Palaeozoic and the Mesozoic. the 1st papers during this booklet current the geological history of those floral and faunal successions, in addition to historic features in their discovery. Descriptions of recent taxa and evaluate papers take care of vegetation, sharks, bony fishes, turtles, crocodilians, dinosaurs and mammal-like reptiles. Papers concerning the Mesozoic palaeobiogeography, environments and climates of Asia finish the volume.The Geological Society of LondonFounded in 1807, the Geological Society of London is the oldest geological society on the planet, and one of many greatest publishers within the Earth sciences.The Society publishes quite a lot of high quality peer-reviewed titles for lecturers and execs operating within the geosciences, and enjoys an enviable foreign popularity for the standard of its work.The many components during which we submit in include:-Petroleum geology-Tectonics, structural geology and geodynamics-Stratigraphy, sedimentology and paleontology-Volcanology, magmatic reviews and geochemistry-Remote sensing-History of geology-Regional geology courses

The prior decade has witnessed a massive revival in makes an attempt to split biodiversity indications from biases imposed by means of sampling and the structure of the rock list. How huge an issue this poses to our knowing of biodiversity styles is still controversial, and new ways are being constructed to enquire this query.

Fossil species seem to persist morphologically unchanged for lengthy durations of geologic time, punctuated via brief bursts of fast swap as defined by way of the Ecological Evolutionary devices (EEUs). the following, morphological edition in Paleozoic atrypide morphology on the subfamily point (Atrypinae and Variatrypinae) from the Silurian and Devonian time durations within the 3rd Paleozoic EEU (~444-359 my) have been investigated utilizing really new concepts of quantitative modeling.

History therefore shows that, during his career, Counillon did not receive the honours he actually deserved. Almost a century after the Pavie Mission, during the 1990s, and within the framework of a French– Lao scientific convention, palaeontologists from THE EXPLORATION OF LAOS BY COUNILLON 31 Fig. 4. Three-dimensional reconstruction of Dicynodon from the Upper Permian of Laos. Courtesy of M. Boulay and S. fr). the Muse´um National d’Histoire Naturelle (Paris; MNHN), headed by P. Taquet and supported by the Fondation de France, rediscovered the Permian fossil localities described by Counillon: they discovered in the Luang Prabang Formation numerous cranial and postcranial remains of dicynodonts, and fragmentary and rare remains of amphibians (Battail et al.

5 km. Possible coeval red beds also occur in southern Peninsular Thailand (Trang Group) and in Peninsular Malaysia (within the Gagau and Tembeling Groups). Up to 3 km of postKhorat Group section was removed in NE Thailand by erosion during Tertiary uplift associated with the collision between India and Eurasia and the formation of the Himalayas (Racey et al. 1996, 1997a, b). Although the Khorat Group crops out on the Indochina Block it does partly extend westwards across the Loei–Petchabun and Sukothai Fold Belts onto the Sibumasu Block, the two blocks having been sutured together since at least the Late Triassic (Figs 1, 2).

P. fr) Abstract: In Laos, dicynodonts have long been known only from one specimen, now lost, a partial skull discovered by Counillon in the purple beds of the area of Luang Prabang, and initially described by Repelin as Dicynodon incisivum. Subsequent researchers attributed the specimen either to the Late Permian genus Dicynodon or to the Early Triassic genus Lystrosaurus. Recent Franco-Laotian expeditions have gathered, from the same purple beds, a collection of tetrapods composed mainly of dicynodonts.
