Size It Up Dinosaurs answer: October 23
The five Dinosaurs silhouettes for October 23, 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 50 ran from a scutellosaurus (1.2 m) to a brontosaurus (22 m). The widest gap was round 5, Scutellosaurus against Abelisaurus, at 7.5×; the closest call was round 3, Eustreptospondylus against Eotyrannus, only 1.4× apart — the kind of round that separates a 90 from a 60.
