Rankle #41 answer: mass extinction event (oldest to most recent)

The answer

Rank by mass extinction event (oldest to most recent)

1. 1Permian-Triassic (the Great Dying)252 mya
2. 2Triassic-Jurassic extinction201 mya
3. 3Jurassic-Cretaceous extinction145 mya
4. 4Cretaceous-Paleogene (dinosaurs end)66 mya

Why this order

Ranked oldest to most recent, Permian-Triassic (the Great Dying) (252 mya) goes at the top and Cretaceous-Paleogene (dinosaurs end) (66 mya) at the bottom.

The closest call is Permian-Triassic (the Great Dying) (252 mya) against Triassic-Jurassic extinction (201 mya), 51 million years apart. That is the swap most likely to cost a point.

The biggest gap is between Jurassic-Cretaceous extinction and Cretaceous-Paleogene (dinosaurs end), 79 million years apart, so that boundary should be the easiest part of the order to get right.

These are the figures the game reveals after you submit. They are rounded; only the order is scored.

Difficulty: easier, judged by how close the tightest pair is.
