Size It Up Dinosaurs answer: October 8
The five Dinosaurs silhouettes for October 8, 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 35 ran from a deinonychus (3.4 m) to a diplodocus (26 m). The widest gap was round 4, Diplodocus against Yutyrannus, at 3.5×; the closest call was round 3, Parasaurolophus against Ceratosaurus, only 1.3× apart — the kind of round that separates a 90 from a 60.
