While allowing that fossils have plenty to tell us about what dinosaurs were like, Hort notes that there are still plenty of unanswered questions—from what they ate and how those massive but tiny-headed plant eaters managed to down enough chow to maintain their weight to what all the spines and spinal plates were for. Echoing the author’s breezy tone, O’Brien casts Triceratops sending each other love notes with their neck frills, Maiasaurs with a stroller full of unhatched offspring, a Tyrannosaur in a restaurant downing both entrees (i.e., dead food) and waiters (live), and the like. Aside from a rhetorical “How much would you like dinosaurs to know about you?” at the end, this will please budding dinophiles as it raises their awareness of the split between paleontological fact and speculation.
