Constructed between January and June, 2003, with epoxy resin and polyurethane, the model has a total length of 130 cm (scale 1:5). The head was constructed based on photos of the fossil of A. limai and Irritator challengeri, obtained from the original papers describing these species. The body was based on the close relationship with Spinosaurus aegyptiacus. The animal was made with a dorsal "sail" based on some fossils of vertebrae, still being described in the Museu Nacional, which present tall neural spines.

Editor's note: although postcranial material is a yet undescribed for this species, the hands would likely have been positioned with the palms facing inward.
