Bennett supports the Biologist assessment of the head crests, which he thinks were used as display structures to attract mates and/or to intimidate rivals.

He said, "I know if I had one of those, women would be throwing themselves at me, convinced of my sexual prowess and reproductive fitness, and men would shrink from me, sure that my strength greatly exceeded theirs."

" ... men would shrink from me, sure that my strength greatly exceeded theirs."

If you can carry that thing around all day, you're no 90-lb weakling!

Ah, the "Just so" stories just keep on rolling in. It will take about 3 weeks for the bio-educrats to strip out "Bennet thinks..." and replace it with "Science says.."

The head crests are not just decorative, or mate-attractors.
They are an essential part of the aerodynamics of the creature. They have no TAIL, therefore they must have some form of structure to allow guidance. The Head crest provides that TAIL GUIDANCE STRUCTURE at the front, instead of at the rear.

I support the billboard theory. They were used to support billboards for that political Dinosaur - the American Democratic Party - during Mesozoic elections.
