The teleosauroid vertebra from the Toarcian of Averyron that you identify as Steneosaurus sp. is best considered generically indeterminate, because Steneosaurus is restricted to the type species S. rostromajor from the Middle Jurassic of Normandy by Johnson et al. (2020), and recent studies (Johnson 2019; Sachs et al. 2019) revalidate Mystriosaurus and resurrect Macrospondylus for 'Steneosaurus' bollensis, while showing that 'S.' gracilirostris represents a distinct genus of its own (I won't mention the new genus name for gracilirostris until Chapter Four of Johnson's 2019 thesis is published).
