The National Archaeological Expedition discovered an underground cemetery that dates back to the 2nd century, al-Baath newspaper said, quoting Khalil al-Hariri, the head of the expedition.
He said archaeologists found a stone door and two engraved statues of a family. The limestone sculptures depict them as wearing clerical hats, the ancient traditional clothes in Palmyra, al-Hariri said.
Palmyra, which is located in central Syria and is said to have been founded by King Solomon, was a trade center that boomed with the decline of ancient Petra in modern-day Jordan.
The city, 240 kilometers (150 miles) northeast of Damascus, emerged to become a powerful state after the Romans took control of it, serving as a link between the ancient Orient and Mediterranean countries.
