Here is a realistic passage supporting the given sentence:

In the late 1970s, a team of archaeologists led by Dr. Maria Bianchi embarked on an ambitious excavation project in the ancient Etruscan port city of Pyrgi, Italy. Over the course of seven years, from 1972 to 1979, the team meticulously uncovered the ruins of the once-thriving metropolis. It was during this extensive dig that they made a groundbreaking discovery - three gold leaf inscriptions, now known as the Pyrgi Tablets, which provided unprecedented insight into the Etruscan language and culture. The tablets, remarkably well-preserved, have since been hailed as one of the most significant archaeological finds of the 20th century.
