Extinct genus of dinosaurs
Evgenavis (named after the Russian paleontologist Evgeny Kurochkin ) is a genus of pygostylian dinosaurs that lived from the Barremian to the Aptian . The type specimen ZIN PH 1/154 is an isolated tarsometatarsus found in the Ilek Formation (Shestakovo locality), Western Siberia . Evgenavis may have been the only confuciusornithiform known outside the Jehol Biota , although there is also the possibility that it could have been a different type of avialan, such as an enantiornithean or a relative of Vorona .[ 1] A cladogram within a 2019 study involving a wide range of theropods included Evgenavis as a longipterygid .[ 2]
