The type specimen of Austroraptor cabazai, holotype MML-195, was recovered in the Bajo de Santa Rosa locality of the Allen Formation, in Río Negro, Argentina. The specimen was collected in 2002 by the team of Fernando Emilio Novas of the Museo Argentino de Ciencias Naturales. It consists of a partial skeleton with large portions of the skull. The fossil was prepared by Marcelo Pablo Isasi and Santiago Reuil. In 2008, the type species Austroraptor cabazai was named and described by Fernando Emilio Novas, Diego Pol, Juan Canale, Juan Porfiri and Jorge Calvo. The genus name Austroraptor means "Southern thief," and is derived from the Latin word auster meaning "the south wind" and the Latin word raptor meaning "thief." The specific name cabazai was chosen in honor of Héctor "Tito" Cabaza, who founded the Museo Municipal de Lamarque where the specimen was partially studied.
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.
