Anelli is a professor and researcher at the Institute of Geosciences at USP (University of São Paulo), specializing in Paleozoic and Cenozoic fossil invertebrates from Brazil and Antarctica, as well as an amateur cyclist. Founder of the USP Replica Workshop, he was responsible for assembling the first dinosaur skeletons in the city of São Paulo, as well as the first replica of a Tyrannosaurus rex skeleton in South America.

Julio Lacerda, a graphic designer and illustrator, entered the world of paleoart at the young age of 17. His work focuses on reconstructing extinct animals, such as dinosaurs, with the naturalistic essence found in wildlife documentaries, seeking to represent the appearance and behavior of these animals as realistically as possible. His illustrations have been published and exhibited in several countries, including Japan (the Pterosaurs exhibition at the Fukui Prefectural Dinosaur Museum), the United Kingdom (the book All Your Yesterdays by Irregular Books), and the United States (a publication on the dinosaur Siats meekerorum for the North Carolina Museum of Natural Sciences).
