Matthew LaCroix built the Lost Civilizations Database using criteria co-developed with Brien Foerster and others, scoring sites on stone hardness, masonry precision, and engineering complexity that seem beyond bronze or iron age tools. Baalbek in Lebanon ranks as the second largest entry, with foundation stones weighing 1,000–1,300 tons beneath later Roman construction. Yangshan, China tops the list, its steles exceeding 16,000 tons. The Great Pyramid holds 2.5 million blocks averaging 3–7 tons, with 50-ton granite pieces raised 150 feet above the King's Chamber. And Dr. Robert Schoch has shown the Sphinx enclosure carries water erosion, not wind erosion, pushing it well beyond dynastic Egypt's 5,000 years.

Key facts
- Matthew LaCroix created the Lost Civilizations Database (LCD), applying criteria developed with Brien Foerster and other researchers
- LCD criteria focus on stone hardness, masonry precision, specific cuts, stone size, and engineering sophistication inconsistent with bronze and iron age tool capabilities
- Baalbek, Lebanon is cited as the second largest megalithic site in the LCD database, with some foundation stones exceeding 1,000 to 1,300 tons
- Baalbek's Roman-era architecture was built on top of pre-existing megalithic foundations of much greater age
- Yangshan, China is identified as the largest megalithic site, with steles exceeding 16,000 tons
- Great Pyramid of Giza described as containing 2.5 million stone blocks averaging 3-7 tons each, with granite blocks over 50 tons hoisted 150 feet above the King's Chamber
- The Great Pyramid allegedly encodes a half-ratio alignment mimicking the Earth-Sun-Moon relationship and the three belt stars of Orion
- Dr. Robert Schoch identified water erosion (not wind erosion) on the Sphinx enclosure, indicating the structure predates dynastic Egypt's last 5,000 years
