Kiyacursor
''Kiyacursor'' (meaning "Kiya (river), Kiya River runner") is an extinct genus of noasaurid theropod dinosaur from the Early Cretaceous Ilek Formation of Russia. The genus contains a Monotypic taxon, single species, ''K. longipes'', known from a partial skeleton. ''Kiyacursor'' represents the first Early Cretaceous ceratosaur discovered in Asia, as well as the second non-avian theropod named from Russia, after ''Kileskus'' in 2010. Discovery and naming The ''Kiyacursor'' holotype specimen, Kuzbass State Museum of Local Lore, KOKM 5542, was discovered in the summer of 2023 in sediments of the Ilek Formation (Shestakovo 1 locality) by the Kiya (river), Kiya River in Kemerovo Oblast, Russia. The specimen consists of an incomplete skeleton, including Cervical vertebrae, cervical and caudal vertebrae, cervical and dorsal ribs, a left scapulocoracoid, humeri, and much of both Joint, articulated hind limbs.

A partial cervical vertebra, PIN 329/16, was first described in 2023 by Averianov & Lopatin as belonging to a long-necked theropod similar to basal therizinosauroids like ''Falca ...

Ilek Formation
The Ilek Formation is a Lower Cretaceous geologic Formation (geology), formation in Western Siberia. Many different fossils have been recovered from the formation. It overlies the Late Jurassic Tyazhin Formation and underlies the Albian Kiya Formation. The formation was described by L. A. Ragozin in 1935. It consists of sands with sandstone concretions, layers of silts, clays and marls. Age of the formation, according to a crude 1962 estimate, is Valanginian(?) - Hauterivian - Barremian. Its thickness varies greatly, reaching 746 m in Teguldetsky District, Teguldet borehole. A more recent 2024 estimate based on invertebrate and vertebrate fossils placed the age of the formation at Barremian–Aptian. Age The Ilek Formation conformably overlies the Upper Jurassic Tyazhin Formation. Gastropods and bivalves of Valanginian age have been recovered from the lower part of the formation, and gastropods and bivalves of Hauterivian to Barremian age have been found in the upper part, as we ...

2024 In Archosaur Paleontology
This article records new taxa of every kind of fossil archosaur that are scheduled to be Species description, described during 2024, as well as other significant discoveries and events related to the paleontology of archosaurs published in 2024. Pseudosuchians New pseudosuchian taxa General pseudosuchian research * Evidence of the impact of function on the evolution of the lower jaw morphology in crocodile-line archosaurs is presented by Rawson ''et al.'' (2024). * A review of studies on the thermometabolism of crocodile-line archosaurs from the preceding 20 years is published by Faure-Brac (2024). * Sennikov (2024) interprets Ornithosuchidae, ornithosuchids as macrophagous predators with specialized jaw apparatus, and notes analogs between them and saber-toothed therapsids (including mammals). * A study on the locomotion of ''Riojasuchus, Riojasuchus tenuisceps'' is published by von Baczko ''et al.''
