Having being a lot since I've animated it was really difficult but I mange to get round it again I just wish I could have had more time to do better work..
I found some really good reference walk cycle of a dinosaur over the internet which i thought might help..
Also had a look at the Richard Willams Book as well as Preston Blair Book
just to look at basic walk cycle keyframes as to help me with the animating.

I also look at a chicken's legs as well as the way it walks since they say that dinosaurs didn't extinct but evolved to birds.. And thought this image I found was quite usefull to help me understand a little bit better on how it would walk and shift his weight.
