Futabasaurus is the first elasmosaurid plesiosaur ever found in Japan.1
Its bones show bite marks from sharks, especially a type called Cretalamna, which scavenged or attacked it after death.1
The name Futabasaurus comes from the Futaba Group of rocks where it was discovered.1
The species name suzukii honors Tadashi Suzuki, the high school student who found the fossils.1
Futabasaurus lived during the Santonian stage of the Late Cretaceous, about 86 to 83 million years ago.2
It had a long neck like other elasmosaurids, and its front flippers were longer than its back ones.1
