For anyone with a taste for creativity and colour, Hadrosaurs -like this strangely crested Olorotitan- simply open the gates for a flood of possibilities. I could finally see a mounted Olorotitan specimen in the Natural History Museum in Brussels (the best dinosaur museum in Europe). It is a lightly-build animal, probably lighter than I depicted it here. But the crest of hadrosaurs is always a challenge to reconstruct (specifically the external appearance and the possibility of external attachments to it). Put that together with the rich skin topography and frill ornaments and you get as many possibilities as imagination allows you. Please note that I have reserved bright colours to display items like crests and frills… although rich skin colour patterns could have been anywhere, given the differences in shapes and size of the scales. The question of colours is… did big dinosaurs have colour vision or not? I contend that they had.I can spend many hours sketching (as this illustration from “Dinosaurs, The Most Complete, Up-To Date Encyclopedia” by Holtz/Rey shows). But the non crested ones are just as fascinating. The construction of the nostrils are a special challenge and the neck musculature is still being debated between the later most favoured “Bison” model and the slender, flexible neck.
All these are older illustrations that led to the Maisaura I included in the mural and specially the “Orchestra attack” by Parasaurolophus from a previous post (which also tried to address the problem: how these animals would defend themselves agains the tyrannosaurs and other predators?). But I think they are experiments worth showing. Here’s an old Maisaura tending the nest (from “Dinosaurs In The Round”).
