Amanzia greppini

†Amanzia greppini was a sauropod dinosaur from the Late Jurassic (~155 Ma) of Switzerland. A large quadrupedal herbivore, it was named from material discovered in the Porrentruy region of the Swiss Jura. It represents one of the rare dinosaur discoveries from Switzerland and contributes to knowledge of the European Jurassic sauropod fauna, which lived on island landmasses of the ancient Tethys Sea.

Diet & Feeding

Herbivore

Amanzia greppini was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Jurassic Late Mesozoic Era

Amanzia greppini lived during the Jurassic Late period of the Mesozoic Era, approximately 161.5 to 145.0 million years ago.

One of the most iconic periods for dinosaurs. Giant sauropods like Brachiosaurus and Diplodocus roamed alongside predators like Allosaurus. Archaeopteryx, the earliest known bird, appeared. The Morrison Formation preserves an extraordinary fossil record from this time.
