 He prepared the strange discovery in the basement of his house in San Giovanni Ilarione near Verona, removing, without the use of any optical instrument, part of the chalk matrix from the top of the bones and covering them with vinyl glue.He strengthened the stone plate by adding pieces to its rim and on one of these he added a fake tail made from polyester resin as that of the fossil was largely lacking because he had failed to recover it completely.In early 1993 Todesco, who had nicknamed the animal "cagnolino", "little doggie", after its toothy jaws, brought the specimen to the attention of paleontologist Giorgio Teruzzi of the "Museo Civico di Storia Naturale di Milano", who identified it as the juvenile of a theropod dinosaur and nicknamed it "Ambrogio" after the patron saint of Milan, Ambrose.
