(ANSA) – Sharp teeth like legs and legs with strong claws like steel distinguish Saltriovenator zanellai, the dinosaur Largest large carnivore found in the world, discovered in present-day Lombarda.
The young keratosaurus lived 200 million years ago. It measured almost eight meters in length and weighed a ton: a war machine, according to the identikit revealed by paleontologists Cristiano Dal Sasso, Simone Maganuco and Andrea Cau. The first Italian dinosaur of the Jursico and the unique Lombard, the Saltriovenator represents a new species that retrodita in 25 million years the appearance of the great predatory dinosaurs. This hunter of ambushes and hikers lives among the tropical beaches and lush forests that cover the present western Lombarda.
His identikit, published in PeerJ magazine, reveals a copy of striking dimensions to him, with an 80-centimeter skull, armed with sharp teeth and skeleton-shaped anterior limbs, three of them powerful with claws.
Its anatomy suggests that the wings of the birds derive from the fusion of the first three fingers of the terpodes dinosaurs. "Although fragmented, the skeleton shows a mosaic of ancestral and derived anatomical characters," said Dal Sasso, a paleontologist at the Natural History Museum who went to California and Washington to identify the most fragmented bones in order to identify accurate skeletal posture more complete. "Not all fragments combine, but many are adjacent and allow us to reconstruct the shape of whole bones. To complete the puzzle, we also use a 3D printer," he explained.
The remains of Saltriovenator represent the first dinosaur bones, in which bites and parts of fish and marine invertebrates were found, that the carcass remained at the bottom of the sea for months or years before fossilizing.
The discovery was made in 1996 in Saltrio (Varese), a quarry known for providing stone blocks to the Teatro alla Scala, Galleria Vittorio Emanuele and the Royal Palace of Milan, as well as part of the Mole Antonelliana and Capella Colleoni. from bergamo.
