Over the last few years, Mauricio has entered the world of computer 3D modeling and animation. He has created accurate digital models of several fossil vertebrates, from sabertooth cats to mammoths and hominids. He has also worked with talented animators to set the creatures in motion. In 2004 he collaborated with artist and animator José Antonio Peñas, who created a sequence showing the sabertooth Homotherium stalking and hunting a Pleistocene deer.
In collaboration with animator Juan Pérez-Fajardo and his company 'The Fly Factory', he has worked in the making of animations of various prehistoric creatures, several of which are shown in Museum and theme Park 'Dinopolis', in Teruel, Spain. Currently they work on a more ambitious project dealing with the evolution of sabertooths.
