Actually, it’s a troodontid.

“The team used a number of methodologies to conclude that, just like 90% of the birds species alive today, it was the male Theropods who did most of the brooding on the nests.”

I think you’re a little confused: It’s not that males do “most of the brooding on the nests” in 90% of extant bird species, but that males “participate in parental care in more than 90% of extant bird species” ( http://www.esf.edu/EFB/faculty/documents/varricchio2008paternalcaredinosours.pdf ).

“Dr. Deeming and his team took a different approach to the statistical analysis. They counted the eggs in all known fossil nests for the Theropod species included in the original study and then worked out an average clutch size for each species. Dr. Varricchio and the Montana State University researchers had based their calculations on the largest clutch size for each dinosaur species.”

That’s 1 of the things I like about Deeming’s new paper: The results of Varricchio et al. 2008 never made sense to me, given that “Troodon clutches vary from 12 to 24 eggs” ( http://www.annualreviews.org/doi/abs/10.1146/annurev.earth.28.1.19?journalCode=earth ).

“Crocodiles don’t incubate their eggs, they just sit on the buried eggs to protect them from predators. I think that’s probably what was going on in the dinosaurs too.”

That’s 1 of the things I dislike about Deeming’s new paper: It’s been pretty much proven that non-avian maniraptorans incubated their eggs by direct body contact ( http://www.bioone.org/doi/abs/10.1666/11042 ).
