Size It Up Dinosaurs answer: November 5
The five Dinosaurs silhouettes for November 5, 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 63 ran from a dromaeosaurus (1.8 m) to a spinosaurus (14 m). The widest gap was round 1, Avaceratops against Ankylosaurus, at 3.5×; the closest call was round 5, Psittacosaurus against Hypsilophodon, only 1.0× apart — the kind of round that separates a 90 from a 60.
