dinosaurs, explaining the already-in-process decline of the dinosaurs before
the asteroid crash, and explaining the rapidity of their final demise.
The problem here is, IMNSHO, that you try to explain the extinction of the
dinosaurs. Yeah, right. :-) Why did the ammonites die out? The rudists and
the inoceramids? Heaps of foraminifera and haptophytes*?
* Coccolithophorida -- the calcareous nannoplankton that chalk is largely
made of -- belong in here.

So did the warm-blooded Neornithes, but not any other bird (except,
depending on the phylogeny, Lithornithiformes, which is either in Neornithes
or its sister group).

You would not love to hear feedback from all hundreds of us :-)
