Size It Up Dinosaurs answer: October 6
The five Dinosaurs silhouettes for October 6, 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 33 ran from a velociraptor (1.8 m) to an acrocanthosaurus (12 m). The widest gap was round 4, Polacanthus against Velociraptor, at 2.8×; the closest call was round 1, Concavenator against Alioramus, only 1.0× apart — the kind of round that separates a 90 from a 60.
