When remains of Shantungosaurus were first found they were found in a bone bed of at least five individual dinosaurs. Though none of these were of a complete skeleton, composites of incorporating the bones of more than one individual have been assembled with the largest producing a hadrosaurid dinosaur just over sixteen and a half meters long, possibly weighing up to sixteen tonnes. To put this in perspective, this currently makes Shantungosaurus the largest known hadrosaurid dinosaur, even larger than other well-known large hadrosaurs such as Edmontosaurus and Magnapaulia.
Chroma key compositing, or chroma keying, is a special effects / post-production technique for compositing (layering) two images or video streams together based on color hues (chroma range). The technique has been used heavily in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion picture and videogame industries. A color range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. The chroma keying technique is commonly used in video production and post-production. This technique is also referred to as color keying, colour-separation overlay (CSO; primarily by the BBC), or by various terms for specific color-related variants such as green screen, and blue screen – chroma keying can be done with backgrounds of any color that are uniform and distinct, but green and blue backgrounds are more commonly used because they differ most distinctly in hue from most human skin colors. No part of the subject being filmed or photographed may duplicate the color used as the backing.
