Dinosaur Rock has virtually all trad style routes. The north face (all day shade) has several good (not great) routes. Negasaurus (5.9) has a bouldery start (the crux) and easier cracks above. Gorgasaurus (5.7) is worth doing, and has a height dependant start. Goolabunga (5.10b) is the best of the lot. It is good steep slab climbing and somewhat continuous. The rock is very good but a bit grainy at the top. The east face routes are sunny but are not the best. There is a reason they named one "Too Loose to Trek!"
I forgot to mention the anchors and rappel setup. From the top of Nega. and Gorga. there is a rappel anchor (east end of summit) consisting of a tied off block. It can be used as the anchor as well. The top of Goolabunga needs 2 large cams (3") for a bomber anchor.
