Would there be any way to safely keep a member of a well-known dinosaur genus (I’m thinking the ones on TV Tropes’ Stock Dinosaurs page) as a pet (assuming it were possible, of course)?

palaeofail-explained:

Velociraptors probably wouldn’t actually be that bad. They’re like turkey-sized and may not actually be pack hunters. If they’re actually solitary, treat it like a fox- larger outdoor enclosure, lots of enrichment. An exotic pet, and not the easiest, but doable.
