@zooboy28 The dinosaurs are all displayed at Heliconia Valley (aka Tiger Trek on the Zoo map) which has been temporarily re-themed as Dinosaur Valley, and interpretives placed along the Rainforest Walk.
@Zooish Thanks. I thought that area was called Heliconia something, but the recent maps don't label it as such, so I thought I was mixing it up with the Heliconia Walk at Jurong. I just looked at a 2002 map of the Zoo, and its called Heliconia Valley there. The Zoo has changed so much since then.
