Systematics

The family Sichuanchelyidae was originally created to accommodate the Middle Jurassic Chinese turtle Sichuanchelys, and it was considered monotypic until Joyce et al. (2016) recovered the problematic Late Cretaceous turtle Mongolochelys from Mongolia as a close relative of Sichuanchelys.[1][2][3] The late Paleocene form Laurasichersis from Europe is the youngest sichuanchelyid, showing that stem turtles in Laurasia outlived the Mesozoic.[4]

gollark: Still unlikely to be worth it if you don't really need it for job reasons.
gollark: Okay, so maybe several tens of kilodollars instead?
gollark: Maybe it'll have more funlolz™ and whatever over a random reasonably priced one but frankly I doubt it's enough to justify the cost.
gollark: I doubt you'll get 200 kilodollars in financial benefit from it.
gollark: We know what you did.
