Abstract

This article focuses on the discovery and description of a new large theropod dinosaur taxon, *Alpkarakush kyrgyzicus* gen. et sp. nov., from the late Middle Jurassic Balabansai Formation in Kyrgyzstan. The partial skeleton includes cranial, axial, and appendicular elements and is assigned to the Metriacanthosauridae, a clade of medium to large-bodied allosauroid theropods previously known mainly from Asia and Europe. Histological analysis indicates the holotype was a late subadult, while a smaller associated specimen represents a juvenile, suggesting possible gregarious behavior. Phylogenetic and biogeographic analyses support a South-East Asian origin of metriacanthosaurids, with subsequent dispersal into Central Asia and Europe during the Jurassic, highlighting the clade’s diversity and wide distribution in Asia.
