The holotype and only known specimen of Futabasaurus suzukii comprises an incomplete skeleton, including most of the skull. Miguel recently had a chance to visit that museum and provided some photos which show details of the skull and postcranium. #plesiosaur #tokyo #japan

Lusonectes was originally described as a plesiosauroid closely related to Microcleidus. Because only an incomplete skull and mandible are preserved, the phylogenetic position of Lusonectes remains uncertain. 3/4

Hi. Thanks for sharing these photos. Unfortunately I cannot tell which element this could be. It has a very odd shape and I wonder if it might be part of a sea turtle. A Campanian tetrapod from Ukraine is surely an interesting find.
