Cryptoclididae

Cryptoclididae is a family of medium-sized plesiosaurs that existed from the middle Jurassic to the early Cretaceous period. They had long necks, broad and short skulls and densely packed teeth. They fed on small soft-bodied preys such as small fish and crustaceans.

Classification

In 2010, two supposed late Cretaceous members of the group were reclassified as other kinds of plesiosauroids. Kaiwhekea was reclassified to Leptocleididae, and Aristonectes was transferred to Elasmosauridae.[3]

gollark: NuclearCraft requires really complex chemical processing factories for advanced things, but basic nuclear reactors and RTGs are cheap.
gollark: For example, even if you just throw all the mods in like I am so far, Botania is complex and rather different to regular tech mods, but you can still have a tiny endoflame set up or something to get the basics.
gollark: Well, yes, you can to some extent, for base investment in mods.
gollark: Also perhaps stargates and other long-range teleporters if I fiddle with the recipes.
gollark: For example, in my very WIP pack, Botania items (especially advanced elven/gaia ones), NuclearCraft fusion reactor/dense energy storage/radiation remover systems, compact machine factories, that sort of thing, require lots of investment in one mod or something like that, so people will probably try and make and sell those.
