Size It Up Dinosaurs answer: October 29
The five Dinosaurs silhouettes for October 29, with the true sizes. If you have not played yet, this page is a spoiler — play these five first, then come back to argue with the numbers.
Day 56 ran from a scutellosaurus (1.2 m) to a brontosaurus (22 m). The widest gap was round 2, Brontosaurus against Dryosaurus, at 5.5×; the closest call was round 1, Megalosaurus against Alioramus, only 1.0× apart — the kind of round that separates a 90 from a 60.
