Size It Up Dinosaurs answer: September 26

The five Dinosaurs silhouettes for September 26, 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 23 ran from a velociraptor (1.8 m) to a baryonyx (10 m). The widest gap was round 4, Velociraptor against Triceratops, at 5.0×; the closest call was round 5, Gigantoraptor against Baryonyx, only 1.3× apart — the kind of round that separates a 90 from a 60.
