- The first Seeleyosaurus fossil was described by German paleontologist Wilhelm Dames in 1895, who named it Plesiosaurus guilelmiimperatoris. In 1940, American paleontologist Theodore White gave it the new genus name Seeleyosaurus.31
- Steeds omstrede
- Scientists still debate whether Seeleyosaurus was a type of elasmosaur or a microcleidid, because different studies place it in different groups.31
