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: IIRC this has issues if the shared thing contains further GCed things.
gollark: I may just do the somewhat horrible channel thing then.
gollark: Images are generated at intervals and then may be used to respond to lots of HTTP requests.
gollark: I guess I could make the thing which needs the images poll a channel from the other thread and put them in a table then, but that seems terrible.
gollark: I have another problem. I need to offload the generation of the image things to another thread, since it's quite slow. It seems that just passing a tableref to `createThread` and having it update that doesn't work, since the table is presumably copied at some point. I looked at channels, but they don't look like they work well with async. What's the best way to do this?
