The Show Off
 
The Show Off     
A generic theropod species displaying speculative courtship behaviour. The dark feathered males have collected dark objects and piled them at the base their own tree stump. The males now stand proud on their tree stumps and the dark feathered females look up from the ground evaluating them, but there is a distraction. A single albino male has collected white objects and piled them around the base of a single sun bleached sauropod rib that is lodged in the soft soil. When the drifting clouds reveal the full moon, a beam of moonlight illuminates his white plumage and he starts his performance.
