Size It Up Dinosaurs answer: November 6
The five Dinosaurs silhouettes for November 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 64 ran from a scutellosaurus (1.2 m) to a carcharodontosaurus (12.5 m). The widest gap was round 5, Yinlong against Albertosaurus, at 7.5×; the closest call was round 4, Tyrannosaurus rex against Carcharodontosaurus, only 1.0× apart — the kind of round that separates a 90 from a 60.
