Dewlap



In a discussion recently, it was brought to my attention that a dewlap is a
flap of skin supported by bone...this raises two questions in my mind.
1. What bones support the dewlap?
2. Does this mean the impression found with the tyrannosaurid (mentioned
last month onlist) is not a true dewlap? Or is there something else?
Peace,
