Pterosaurs, Ichthyosaurs, Plesiosaurs, and a Coupla Placodonts 'R' Us

About

Not dinosaurs, which have their own list. These are all Not Dinosaurs, but they are not not-dinosaury-enough to be on the Not Dinosaurs list.

Includes pterosaurs, ichthyosaurs, plesiosaurs (including pareiasaurs), and a few placodonts. Tags should differentiate between these and also indicate time periods in which they lived. Suggestions/corrections welcome (this is a work in progress).

Still can't decide if nothosaurs should go on this list, or perhaps on the archosaurs list.
