Khuren Dukh Formation
The Khuren Dukh Formation, also known as the Hühteeg Svita, (Mongolian: Хөхтээг формаци, Khökhteeg Formatsi) is a geological formation in Mongolia whose strata date back to the middle to late Albian.[1] Dinosaur remains are among the fossils that have been recovered from the formation.[2]

Notes Uncertain or tentative taxa are in small text; |
gollark: voltage on primary/voltage on secondary = turns on primary/turns on secondary if I remember right, and the power on both things is the same (ignoring losses).
gollark: Just solve for a.
gollark: v = end velocity, u = start velocity, a = acceleration, s = distance.
gollark: My physics data/formulæ sheet says v² = u² + 2as.
gollark: I think there's an equation for that.
