Answer:
Today the Church celebrates the feast of St. Athanasius of Alexandria who is a Doctor of the Church, as well as a great theologian who united the Eastern and Western Churches. A great deal of his work and mission was responding to the Arian heresy running rampant in his day. In fact, the Arian heresy has proved to be one of the most virulent heresies and can be seen in various forms even in our own day.
He was born around 300 AD in Alexandria, Egypt. After receiving a quality education, he became a deacon and secretary to the Bishop of Alexandria. He worked closely with the Bishop and attended the first Ecumenical Council at Nicaea in 325 AD. This Council focused primarily on the divinity of Christ in response to the Arian heresy which had been advanced through the Alexandrian priest Arius.
Explanation:
The correct answer is Huayangosaurus, middle Jurassic.
A genus of stegosaurian dinosaurs called Huayangosaurus lived in China during the Middle Jurassic. The name is a combination of the words "Huayang," another name for Sichuan, and "Saurus," which means "lizard." About 165 million years ago, during the Bathonian to Callovian stages, it lived, some 20 million years before the arrival of its renowned related Stegosaurus in North America. It was also considerably smaller than its well-known cousin, measuring only about 4 meters (13 feet) long. The sauropods Shunosaurus, Datousaurus, Omeisaurus, and Protognathosaurus, the ornithopod Xiaosaurus, and the carnivorous Gasosaurus shared the region's Middle Jurassic terrain with Huayangosaurus, which was discovered in the Lower Shaximiao Formation.
