Everything Dinosaur team members get the chance to view all sorts of different examples of prehistoric artwork and illustrations. We are grateful for Caldey for sending into us her illustration of the Late Jurassic theropod Allosaurus, a dinosaur that is sometimes referred to as the “lion of the Jurassic”.

The Theropod Allosaurus
Like many aspiring palaeoartists, young Caldey has been experimenting by using different techniques to create the impression of the texture of reptilian skin. In her illustration of Allosaurus, she has used a different method to produce the scales of this large, meat-eating dinosaur. Coloured dots have been used to create the illusion of rough scales and we think the end result is most impressive.
The flash of red is very distinctive over the eyes. Allosaurus had a pair of small horns just above each eye-socket. These horns were actually extensions of the lacrimal bones that are located just in front of the eyes and help to form the orbit. These bones, in turn, were probably covered in keratin and they could have been quite colourful, perhaps having a role in visual displays.
This specimen has scars located on both the upper and lower jaw. These injuries could have occurred when tackling prey or perhaps during intraspecific combat, for example, face-biting behaviour has been postulated for a number of theropods.
Selecting the Colouration
Caldey has also used her own colour palette based on their environment and her research as to which habitats could have been home to this Late Jurassic predator (possible forest and plain areas). She has also mentioned that it would be great if a manufacturer would make an Allosaurus model in this colour scheme.
Our thanks again to Caldey for sending her drawing into us.
