The genus was discovered on the banks of the Kiya River in 2008. Unable to excavate the fossils from the rocks, palaeontologists were forced to extract fragments. They were subsequently taken to Tomsk State University, where experts examined the fossils. It was informally nicknamed "Sibirosaurus" in the press in 2015 and then renamed to Sibirotitan in 2017.
