The other paper you are thinking of is probably this one:

extinction. Geol. Soc. Am. Spec. Pap. 238: 63-70.
That sounds about the right time.
The scientific value would be in trying to deduce a pattern of
survival and sex determination, but I'm not convinced that's
possible. The headline value is certainly there, and explains how it
got reported anywhere. -- Jeff Hecht
I haven't read either of them yet, so I don't know what new
information Miller et al. are adding.
I don't understand how this theory is to have any scientific value,
since no one knows how to study sex determination in non-neornithean
dinosaurs. They might as well be writing about the implications of
dinosaurs having been a particular colour. Looks like a publicity
stunt to me: "Dinosaurs", "Extinction" and "Sex" in one headline!
