Opening History
In the 1920s, Anatoly Nikolayevich Ryabinin discovered fragments of a creature that he called vetugazavr: he was discovered on the banks of the Vetluga in the Kostroma province in the vicinity of the village of Zubovsky (now defunct) [3] .
The following such finds were made in 1927 by I. A. Efremov at the Pyschug volost village. There, in the area of the Fedrosov rivers (they are now being signed on the map as Ferdos), Efremov, who does not exist now in the forest, dug up similar fossils [4] .
In August 2018, in the southeast of the Samara region, employees of the Samara State Technical University during the expedition discovered the fullest skull of the vetligosaur [5] .
