Cup of Rogan: Cassie Coppersmith’s Secrets-in-Stone Espresso
Independent researcher and Secrets in Stone host Cassie Coppersmith takes Joe on a world tour of “too precise for the tools” megaliths — from Liangzhu jade cong tubes to Angkor’s melted core, a thousand-ton Bahubali, and a disputed second Sphinx under the sand.

Introduction
Cassie Coppersmith — independent researcher of ancient civilizations and host of Secrets in Stone — joins after Joe caught her Megalithic Marvels segment on Chinese jade that shouldn’t look factory-made. The episode is a photo-and-travel brief across China, India, Cambodia, Peru, Egypt, and the Amazon LIDAR map.
Liangzhu Jade and Hardstone Parallels
British Museum wall of nephrite jade: cong tubes (round inside, square outside) and flat bi discs with geometry that ‘resembles machine-turned work.’ Conventional attribution to Liangzhu; Cassie’s frame is Egypt-hardstone-vase energy — precision objects that later cultures buried by the thousands as grave goods, possibly found or inherited rather than invented with copper-age kits.
Temples as Palimpsests
Indian temple halls with interlocking mortarless stone and pillars so precise they look lathed — then crude work above/below where later builders reused older columns. Dating often rests on royal inscriptions (Joe: graffiti). Angkor Wat: three layers, five melted-looking central towers of deities, outer rings of war scenes; LIDAR showing vast engineered landscapes under jungle. Bahubali in India: ~60 feet, ~1,000 tons of white granite, ear lobes measured in feet — living-stone-from-the-mountain story vs. moved block debate.
Skulls, Surgery, and Kings Who Lived Forever
Elongated skulls Cassie has seen in multiple countries; some lack expected sutures and sit differently on the spine than cradle-board examples. Trepanation holes that look drilled — and healed, meaning survivors. Digression into Goliath cubit math (Dead Sea Scrolls vs. taller Hebrew readings) and life-extension tech as a modern Sumerian king-list fantasy.
Second Sphinx and Closing Anomalies
Filippo Biondi–style satellite/radio tomography claims of a sphinx-shaped structure under sand piled from nearby tomb excavations; AI probability chatter >80%; critics say modern mound — Cassie says the signal is below the pile and Egypt could settle it with a shovel. Amazon LIDAR cities, Younger Dryas wipe ideas for North America, Sage Wall skepticism, and a mystery desert fortress round out the tour.
Watch JRE #2528 on YouTube, then fall down Cassie’s travel-photo rabbit holes — bring skepticism and a hard hat.
Top Sips
"They just look machined. They look way too precise for the tools that they say built them."
- Her origin hook: Liangzhu nephrite jade cong tubes and bi discs at the British Museum.
"That's great. It's graffiti."
- On dating Indian/Cambodian temples by later kings’ inscriptions carved onto older stone.
"In my mind, this thing is clearly machined. It's absolutely perfect. Those ears are five and a half feet long."
- On India’s ~60-ft, ~1,000-ton Bahubali granite statue — largest ancient standing statue vibe.
The Blend
- Cold open via Megalithic Marvels: Liangzhu jade that looks lathed, parallel to Egyptian hardstone vases — maybe gifted/found tech that became sacred grave goods by the thousands.
- Temple archaeology as palimpsest: precision ‘lathe’ pillars reused inside cruder later builds; Angkor Wat’s melted-looking five-tower core vs. outer war/elephant layers; LIDAR revealing engineered rainforest cities with millions of people.
- Weird biology + Egypt rabbit holes: elongated skulls across countries that aren’t just cradle-boarding, trepanation that people survived, Goliath-as-ballplayer cubit math, and Filippo Biondi-style satellite scans claiming a second Sphinx under piled excavation sand (~80% AI odds, still dig-to-prove).
Bitter Notes
- Inscriptional dating can be circular — kings tagging older cores doesn’t prove they built the precision work.
- YouTube + AI junk makes genuine anomalies harder to signal; academia’s ‘I went to Cambridge’ shrug doesn’t help either.
- North American ice-age wipe theories imply lost structures here may simply be gone — absence of evidence isn’t evidence of absence, but it’s also not a free pass.
Extra Shot
- Rotating temple pillar lore that ‘used to spin’ — myth or seized mechanism, nobody’s sure.
- Sage Wall in Montana: Cassie isn’t sold; Joe still stares at the stacked-looking bits.
- Random desert fortress of straw-sand-clay with no solid explanation — middle-of-nowhere archaeology jump-scare.
