Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is a subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya and their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds.
The Kyzylkum Desert is the 15th largest desert in the world. Its name means Red Sand in Turkic languages. It is located in Central Asia, in the land between the confluent rivers Amu Darya and Syr Darya, a region historically known as Transoxania. Today it is divided between Kazakhstan, Turkmenistan and Uzbekistan. It covers about 298,000 km2 (115,000 sq mi).
The Enantiornithes, also known as enantiornithines or enantiornitheans in literature, are a group of extinct avialans, the most abundant and diverse group known from the Mesozoic era. Almost all retained teeth and clawed fingers on each wing, but otherwise looked much like modern birds externally. Over eighty species of Enantiornithes have been named, but some names represent only single bones, so it is likely that not all are valid. The Enantiornithes became extinct at the Cretaceous–Paleogene boundary, along with Hesperornithes and all other non-avian dinosaurs.
Azhdarchidae is a family of pterosaurs known primarily from the Late Cretaceous Period, though an isolated vertebra apparently from an azhdarchid is known from the Early Cretaceous as well. Azhdarchids are mainly known for including some of the most largest flying animals discovered, but smaller cat-size members have also been found. Originally considered a sub-family of Pteranodontidae, Nesov (1984) named the Azhdarchinae to include the pterosaurs Azhdarcho, Quetzalcoatlus, and Titanopteryx. They were among the last known surviving members of the pterosaurs, and were a rather successful group with a worldwide distribution. Previously it was thought that by the end of the Cretaceous, most pterosaur families except for the Azhdarchidae disappeared from the fossil record, but recent studies indicate a wealth of pterosaurian fauna, including pteranodontids, nyctosaurids, tapejarids and several indeterminate forms. In several analyses, some taxa such as Navajodactylus, Bakonydraco and Montanazhdarcho were moved from Azhdarchidae to other clades.
Sergei Aleksandrovich Buturlin ; 22 September 1872 in Montreux – 22 January 1938 in Moscow was a Russian ornithologist. He was a pioneer in Russia of the study of the diversity of species and described more than 200 new species of bird.
Unified Sports Classification System of the USSR is a document which provided general Soviet physical education system requirements for both athletes and coaches.
Kuszholia is the name given to a genus of primitive birds or bird-like dinosaurs from the Late Cretaceous. They were possibly coelurosaurs close to the ancestry of birds, although most scientists have considered it an avialan. Fossils were found in the Bissekty Formation in the Kyzyl Kum desert of Uzbekistan.
Arambourgiania is an extinct genus of azhdarchid pterosaur from the Late Cretaceous period of Jordan, and possibly the United States. Arambourgiania was among the largest members of its family, the Azhdarchidae, and it is also one of the largest flying animals ever known. The incomplete left ulna of the "Sidi Chennane azhdarchid" from Morocco may have also belonged to Arambourgiania.
Zhyraornis is a genus of prehistoric bird from the late Cretaceous period. Its fossils have been found in Bissekty Formation deposits near Dzharakuduk in the Kyzyl Kum, Uzbekistan. Two species have been assigned to this genus: Zhyraornis kashkarovi and Zhyraornis logunovi. Both are known only from partial pelvic bones (synsacra).
Bogolubovia is a genus of pterosaur from the Upper Cretaceous Rybushka Formation of Petrovsk, Saratov Oblast, Russia. It is named for Nikolai Nikolaevich Bogolubov, the paleontologist who discovered the remains in 1914. It was in 1991 assigned to the Azhdarchidae. Wellnhofer (1991) however, retained it in the Pteranodontidae. Bogolubov had initially assigned the specimen, consisting of a single partial large cervical vertebra, as a new species of Ornithostoma, O. orientalis. It was later reclassified as a species of Pteranodon, before being assigned its own genus by Lev Nesov and Alexander Yarkov in 1989. The holotype has probably been lost, but other partial remains have been referred to the genus.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1989.
Deltatheroida is an extinct group of basal metatherians that were distantly related to modern marsupials. The majority of known members of the group lived in the Cretaceous; one species, Gurbanodelta kara, is known from the late Paleocene (Gashatan) of China. Their fossils are restricted to Central Asia and North America. This order can be defined as all metatherians closer to Deltatheridium than to Marsupialia.
Aidachar is an extinct genus of ichthyodectiform teleost ray-finned fish from the Late Cretaceous of Kyzyl Kum, central Asia. It was named by Lev Nesov in 1981. At first, he tentatively described the fossil material as the jaw fragments of a ctenochasmatid pterosaur, but reinterpreted Aidachar as a fish in 1986. The type species is A. paludalis. Second species, A. pankowskii, is described from Kem Kem Group and reclassified from genus Cladocyclus.
The Bissekty Formation is a geologic formation and Lagerstätte which crops out in the Kyzyl Kum desert of Uzbekistan, and dates to the Late Cretaceous Period. Laid down in the mid to late Turonian, it is dated to about 92 to 90 Ma.
The Kurds in Azerbaijan,, form a part of the historically significant Kurdish population in the post-Soviet space. Kurds established a presence in the Caucasus with the establishment of the Kurdish Shaddadid dynasty in the tenth and eleventh centuries. Some Kurdish tribes were recorded in Karabakh by the end of the sixteenth century. However, virtually the entire contemporary Kurdish population in the Republic of Azerbaijan descends from migrants from 19th-century Qajar Iran.
The Balabansai Formation is a geological formation in Kazakhstan, Kyrgyzstan and Uzbekistan whose strata date back to the Bathonian and Callovian stages of the Middle Jurassic. Dinosaur remains are among the fossils that have been recovered from the formation. The lithology primarily consists of variegated sandstones, siltstones, claystones, and rare gravels and marls. Many taxa have been found in the formation, including amphibians and mammals
The Pamirid race, also Pamir-Fergana race, is the most Eastern subrace of the Europid race, a racial category is now considered to be obsolete. It was said to be common in Central Asia, represented mostly by the Tajiks, Uyghurs and the Pamir people and Uzbeks. Characterized by brachycephalic skull, dark hair, white skin, narrow protruding nose and fairly strong development of the tertiary hair cover.

Kansaignathus is an extinct genus of dromaeosaurid theropod from the Late Cretaceous Yalovach Formation of Tajikistan. The genus contains only one species, the type species, K. sogdianus. The generic name of Kansaignathus comes from near the town of Konsoy where it was discovered and the Greek word "gnathos" meaning "jaw". The specific epithet "sogdianus" is derived from the historical region of Sogdiana, which was an ancient name for the Fergana Valley region where the fossil was discovered. Kansaignathus is known from a single right dentary bone and a few post-cranial bone fragments. It was the first, and so far the only, dinosaur from Tajikistan to be described and named.
