Build the plan
Work through the premise, audience, argument, and open questions in an editable plan.
Pachycephalosaurus op-ed
An editable plan the draft and review can both use as context.
The dome evolved for display, not combat.
Readers who know the head-butting story but not the evidence against it.
The familiar combat explanation persists because it is vivid, not because it fits the bone.
Old story → CT evidence → display hypothesis → what the revision changes.
Help me shape this into an op-ed.
I tightened the thesis, named the reader we need to persuade, and marked the evidence the argument still needs.
