[1][full citation needed] As a teenager in Caracas (Venezuela) in the 1970s, Antón became fascinated with the skeleton of the saber-tooth cat Smilodon fatalis on exhibition at the local museum.

As he puts it in one of his books (El secreto de los fósiles)[2] “It is the responsibility of the scientific paleo-illustrator to make sure that his images rigorously transmit the knowledge that the paleontologists have gathered from specific extinct species.” To do this he gathers data from extant species, travelling the world extensively, working hands on with fossils, dissecting specimens donated by zoos, researching extinct species with specialists and using extant ecosystems as a basis for the reconstruction of past ones.

He has been an advisor on paleobiology, biomechanics, animal locomotion, and habitats of extinct vertebrates for various media (BBC, National Geographic Society, Natural History, Discovery Channel, etc.).

He has benefited from the influences of paleoart masters such as Charles R. Knight, Rudolph Zallinger, Zdenek Burian, Jay Matternes and others from whom he not only recognizes the technological advances but also the conceptual progress they made.

In recent years, Antón is leading art safaris to Northern Botswana under the title "Drawing the Big Cats", sharing first-hand sightings and his experience in studying the anatomy and evolution of felids with artists from all around the world.
