Size It Up Dinosaurs answer: October 30
The five Dinosaurs silhouettes for October 30, 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 57 ran from a caudipteryx (1 m) to a diplodocus (26 m). The widest gap was round 1, Diplodocus against Deinocheirus, at 2.6×; the closest call was round 2, Scelidosaurus against Chasmosaurus, only 1.3× apart — the kind of round that separates a 90 from a 60.
