Cretaceous Russia

Gobiconodon is an extinct genus of carnivorous mammals (or possibly non-mammalian mammaliaforms) belonging to the family Gobiconodontidae. Undisputed records of Gobiconodon are restricted to the Early Cretaceous of Asia and North America, but isolated teeth attributed to the genus have also been described from formations in England and Morocco dating as far back as the Middle Jurassic. Species of Gobiconodon varied considerably in size, with G. ostromi, one of the larger species, being around the size of a modern Virginia opossum. Like other gobiconodontids, it possessed several speciations to

Berriasella is a discoidal evolute perisphinctacean ammonite, and type genus for the neocomitid subfamily Berriasellinae. Its ribbing is distinct, consisting of both simple and bifurcated ribs that extend from the umbilical seam across the venter; its whorl section generally compressed, the venter more or less narrowly rounded. The species Berriasella jacobi traditionally has been regarded an index fossil defining the base of the Cretaceous, however since 2016 this had been replaced by the first occurrence of Calpionella alpina. Some authors regard B. jacobi as instead belonging to the genus S

Saratovia is a genus of targaryendraconian pterosaurs that lived during the Late Cretaceous in what is now Russia. The genus contains a single species, S. glickmani, known from a partial lower jawbone, and is named after the city of Saratov, where the specimen was found, and its discover Leonid S. Glickman. The fossil comes from sedimentary rocks of the Melovatka Formation. Uncovered in the 1940s, the only specimen was assigned to various genera such as Ornithocheirus, Anhanguera and Coloborhynchus before being recognized as a new taxon and named in 2025. Likewise, though long thought to belon
