Did dinosaurs and pterosaurs practise mutual sexual selection?

Why were elaborate cranial ornaments so diverse and so widespread in pterosaurs and Mesozoic dinosaurs? These structures – grouped together here as ‘cranial crests’ – vary markedly in form and position: they range from the semi-circular blades and keels present at the snout-tips of ornithocheiroid pterosaurs to the hollow tubes, fans and plate-like crests of lambeosaurine hadrosaurs and the bony frills of ceratopsians...

All the whales of the world, ever (part I)

The Wealden Bible: English Wealden Fossils, 2011

Finally, I have in my possession a copy of English Wealden Fossils , the massive, significant and long-awaited new volume published by the Palaeontological Association as part of its Field Guide to Fossils series (this is number 14 in the series)...
