Re: Dino/bird amphibians & Carcharocles [Carcharodon] megalodon

I started to answer the last post, and decided I stayed up too late too, and
I was describing aquatic dinosaurs as feathered and flighted!  When I looked
again at the post, it described hesperiformes as aquatic.

I thought that hesperiformes were one of the Cretaceous groups about which
there is not agreement on whether they are birds, or cousins.  But I don't
have all those groups committed to memory.

An unknown to me proportion of the debate is motivated by the continued
refusal of some scientists to think that nonavian dinosaurs were built like
birds and had feathers.
