RE: Hell Creek Eggshell

I've read both "Dinosaur Eggs and Babies" and "Eggs, Nests, and Baby Dinosaurs: A Look at Dinosaur Reproduction" (both very well-written) but there is little to nothing on Hell Creek eggshell per se. There isn't even that much apparently on Judith River eggshell either. I found Sahni's 1972 "Vertebrate Fauna of the Judith River Formation" but it too is outdated because it doesn't use parataxonomy (only Dinosaur eggshell Class A, B, and C). OK, so there are no Orodromeus (or Hypsilophodont, generally) eggs with identifiable embryos known? And nothing on Hell Creek eggshell since 1999?

Partly outdated, especially in Orodromeus/Troodont -chapter.
