Haman Formation

The Haman Formation is an Early Cretaceous geological formation in South Korea. It has been dated to the Albian, with an estimated maximum depositional age of 105.4 ± 0.4 Ma.[1] The deposit is known for its tracks, including those of dinosaurs,[2][3] pterosaurs and birds.[4][5][6] It overlies the Silla Congomerate which overlies the Chilgok Formation. It is laterally equivalent to the Sagog Formation.[7]

gollark: Basically, it seems very much as if stuff autocrafts, then it vanishes.
gollark: I've probably managed to do the first successful autolosing of items.
gollark: Each individual piece works when I test it then breaks under real-world use, but WHY?
gollark: > tries to implement feature which shouldn't be awfully complicated> wants to rewrite entire project in different programming language
gollark: This is ridiculous: ```local function cost(i) [lua junk here] endlocal function craft(i) [blablabla] cost(i) [blablabla] end -- that cost call errors about calling a nil value```
