Conway Formation
The Conway Formation is a Campanian to Danian geologic formation in the South Island of New Zealand and therefore crosses the Cretaceous–Paleogene boundary. Plesiosaur remains are among the fossils that have been recovered from its strata. The Conway Formation is part of the Eyre Group and Haerenga Supergroup.

Fossil content
Among others, the following fossils have been found in the formation:[1]
gollark: I definitely need you to reverse engineer #3, since I didn't write it, so do that.
gollark: Everyone knows that the best C programmers forego dynamic memory allocation.
gollark: What about the other FORTHy define one?
gollark: Basically, I used osmarkslisp™ to implement a depth first search to find the optimal program to SIMD bubblemergesort a list of arbitrary geometrically distributed integers.
gollark: I finished my entry before the contest even began.
