paleonet dinosaur question

["Marc Laflamme" <marc_laflamme@xxxxxxxxxxx>]

Hello,
I have a question for all of the vert. paleo people out there. I am running 
an intro lab on cladistics, and in order to ensure a good enough student 
attendance, we chose to study the phylogeny of dinosaurs. I have a question 
concerning a feature in Deinonychus. Did it have "belly ribs" like we see in 
T-rex and many of the other theropods? If not, was this character lost?

My lab is coming up soon, so a quick and dirty answer would be great!

Thank you,
