The long-necked elasmosaurs are one of the most unusual of all prehistoric animals. Most elasmosaurid toys and figures are allocated to the genus Elasmosaurus, the most famous of the very long-necked plesiosaurs, however, in reality Elasmosaurus platyurus is quite a poorly known species, and much of the original skeleton has been lost.
