Seeleyosaurus

Seeleyosaurus is an extinct genus of plesiosaur. It is known from a large almost complete skeleton from the Upper Lias (Toarcian) of Württemberg, Germany. There seems to be the impression of a rhomboidal flap of skin in a vertical plane; if so, many plesiosaurs may have been equipped in this way.[1] The holotype was destroyed in 1945 (WWII) and only a cast exists today. A second specimen, preserved in 3D, has survived until today.

The following cladogram follows an analysis by Ketchum & Benson, 2011.[1]

gollark: You have to deal with trusting a server and maybe key distribution and stuff.
gollark: Fair, although they're somewhat more *complex* than "magic uninterceptable channel"l.
gollark: So only stuff like PotatOS ship strong crypto nowadays.
gollark: The other way would be some sort of hypercomplex crypto solution, but it would probably have its own problems and I think SquidDev said no to including that sort of thing in core CraftOS.
gollark: If they made it magically uninterceptable, that would be uncool and bad for learning.
