Size It Up Dinosaurs answer: October 3
The five Dinosaurs silhouettes for October 3, 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 30 ran from a dromaeosaurus (1.8 m) to a diplodocus (26 m). The widest gap was round 2, Centrosaurus against Diplodocus, at 4.3×; the closest call was round 3, Psittacosaurus against Dromaeosaurus, only 1.1× apart — the kind of round that separates a 90 from a 60.
