| - When T. carpenteri was considered a species of Dakosaurus, its relatively long snout and smaller, more numerous teeth were thought to be features retained from more basal metriorhynchids. Because of this, the species was seen as a transitional form between long-snouted, piscivorous metriorhynchids and hypercarnivorous, short-snouted species of Dakosaurus.[3] The species was named to honour Simon Carpenter, an amateur geologist from Frome in Somerset, who provided access to the fossil material.

| - When T. carpenteri was considered a species of Dakosaurus, its relatively long snout and smaller, more numerous teeth were thought to be features retained from more basal metriorhynchids. Because of this, the species was seen as a transitional form between long-snouted, piscivorous metriorhynchids and hypercarnivorous, short-snouted species of Dakosaurus.[3] While Dakosaurus and Geosaurus have ziphodont dentitions with teeth that are laterally compressed, Torvoneustes is unique in having a false-ziphodont dentition. The common ancestor of Dakosaurus and Geosaurus may also have had a ziphodont dentition, and as Torvoneustes is also a descendant of this common ancestor, it is possible that a ziphodont dentition was secondarily lost in the genus. However, it is also possible that Dakosaurus and Geosaurus acquired similar dentitions independently, and that Torvoneustes is not descended from a ziphodont ancestor.[2] The species was named to honour Simon Carpenter, an amateur geologist from Frome in Somerset, who provided access to the fossil material.
