Angela Micol, who last year found the structures using Google Earth 5,000 miles away in North Carolina, says puzzling features have been uncovered during a preliminary ground proofing expedition, revealing cavities and shafts.
Located about 90 miles apart, the two possible pyramid complexes appeared as groupings of mounds in curious positions.
One site in Upper Egypt, just 12 miles from the city of Abu Sidhum along the Nile, featured four mounds with an unusual footprint.
Some 90 miles north near the Fayum oasis, the second possible pyramid complex revealed a four-sided, truncated mound approximately 150 feet wide and three smaller mounds in a diagonal alignment.
Authoritative geologists and geo-archaeologists were largely skeptical and dismissed what Micol called "Google Earth anomalies" as windswept natural rock formations -- buttes quite common in the Egyptian desert.
The couple, Medhat Kamal El-Kady, former ambassador to the Sultanate of Oman, and his wife Haidy Farouk Abdel-Hamid, a lawyer, former counselor at the Egyptian presidency and adviser of border issues and international issues of sovereignty, are top collectors of maps, old documents, books and rare political and historical manuscripts.
According to the couple, the formations spotted by Micol in the Fayum and near Abu Sidhum were both labeled as pyramid complex sites in several old maps and documents.
"For this case only, we have more than 34 maps and 12 old documents, mostly by scientists and senior officials of irrigation," El-Kady and Farouk told Discovery News.
For the site near the Fayum, they cited three maps in particular -- a map by Robert de Vaugoudy, dating from 1753, a rare map by the engineers of Napoleon Bonaparte, and a map and documents by Major Brown, general of irrigation for Lower Egypt in the late 1880s.
