Inside ritual complex 6D-XV at Tikal, archaeologists uncovered a one-of-a-kind Teotihuacán altar in 2024/25—complete with emerald Pachuca obsidian, a human-sacrifice deposit and the mask of the Central-Mexican storm god Tlaloc. Scroll down for the full story, images, a timeline and practical travel tips.
A Dawn That Re-wrote History
5:17 a.m. in Guatemala’s Petén rainforest. Howler monkeys launch their guttural chorus while dew drips from giant Ceiba leaves. In the blue-grey half-light, archaeologist Dr Camila Ruiz kneels over an unremarkable patch of grass. One careful trowel swipe—limestone splinters, flecks of Maya blue and hematite red cascade out. A heartbeat later an emerald flash appears: a double-edged Pachuca obsidian blade. Work halts—jungle silence.
What first looked like another ceramic pit is in fact a perfectly preserved, polychrome altar from Central Mexico, hidden for more than 1 600 years. Even veteran researchers whisper “Indiana Jones…”.

What Was Found?
Just 200 m east of the Great Plaza, complex 6D-XV opens a time-window onto the late A.D. 300s—right after the famous Entrada of 378, when Teotihuacán forces overthrew Tikal’s king.
At the chamber’s heart lies an altar fronted by four finely painted limestone panels. Maya blue, hematite red and deep soot black depict storm-god Tlaloc—ringed eyes, nose-bar, feathered headdress, round shield—iconography straight from a metropolis 1 200 km away and unknown in the Maya Lowlands.
Structure 6D-XV-Sub-3 measures c. 6.2 × 5.4 m, and the painted altar rises 1.15 m; each of its four panels is a tidy 78 cm square
In front lay a sacrifice deposit: the skeleton of one adult male and two or three children, one still slumped in a seated pose. A double-edged Pachuca blade gleamed across the man’s chest—its emerald tint betraying Central-Mexican origin.
Besides the green Pachuca obsidian dart point, the cache held 17 sherds of Thin Orange ware, two shell-trumpet mouthpieces, and pigment cups whose residues, checked by p-XRF, register hematite red and cinnabar.
Osteological analysis identified a 35-year-old male and two or three children aged 7–9; cut marks on cervical vertebrae indicate ritual decapitation, while preliminary strontium-isotope values place all three in the central Petén.
The excavation is part of the Proyecto Arqueológico del Sur de Tikal (PAST), led by Edwin Román Ramírez and Stephen Houston and supported by the PACUNAM LiDAR Initiative and the Hitz Foundation
Centuries later, between A.D. 550 – 645, the entire shrine was packed with clay and disguised as lawn. Why? Maya scholar Prof. Stephen Houston suspects political TNT:
“It’s almost as if Tikal poked the beast and got too much attention from Teotihuacan. That’s when foreigners started moving into the area.”
Stephen Houston, Brown University (2025)
His words make clear how deeply the discovery reaches into the web of power connecting the two great cities—even to the point of deliberate erasure of history.
| Feature | Details |
|---|---|
| Findspot | Residential-and-ritual complex 6D-XV, 200 m east of the Great Plaza |
| Dating | Late A.D. 300s, shortly after the Entrada of A.D. 378 |
| Iconography | Altar with four limestone panels painted in Maya Blue, hematite red, and soot black, depicting the storm-and-rain god Tlaloc with feathered headdress, nose bar, and round shield |
| Sacrificial deposit | 1 adult male & 3 children (one seated) + double-edged Pachuca obsidian blade |
| Closure | Temple systematically back-filled ca. A.D. 550–645 and disguised as an innocuous green space |
Why Is the Discovery Important?
1 · A Perfect Keyhole View
Most traces of Teotihuacán in the Maya Lowlands are mere sherds, scattered murals or isolated artefacts. Here, by contrast, an entire cult precinct lies exactly where its builders left it—a frozen archaeological “snapshot” with zero missing pieces. Researchers can analyse architecture, wall art, sacrifice deposit and environmental data in their original relationship.
2 · Proof of Real Migrants—Not Just Trade Goods
The talud-tablero masonry, emerald-green Pachuca obsidian and child sacrifices all point to people from Teotihuacán who lived, worshipped and died here permanently. This was no exotic import shop but a genuine highland enclave in the rainforest.
3 · Political Dynamite
Radiocarbon dates pin the altar immediately after the Entrada 378 CE—the coup in which General Siyaj K’ahk’ seized Tikal’s throne. The find is a stone footnote to one of Mesoamerica’s most dramatic power shifts and fuels the narrative that Teotihuacán wielded far more than mere commercial influence.
4 · Buried Memory
Between 550 and 645 CE the sanctuary was packed with earth right up to the roofline and disguised as an innocuous lawn. This deliberate “cover-up” suggests later Maya rulers deemed the episode too explosive—an early case of damnatio memoriae.
Fun fact: Dried flecks of copal resin still cling between the panels—likely the last incense before sealing the shrine.
| Reason | Significance |
|---|---|
| Unique in situ | First fully preserved Teotihuacán cult site in the Maya Lowlands—an archaeological snapshot rather than a jigsaw of sherds. |
| Migration evidence | Architecture, sacrificial remains and Pachuca obsidian all indicate that Central-Mexican people lived and died in Tikal, not merely traded there. |
| Political thriller | Dated precisely to General Siyaj K’ahk’’s takeover in 378 CE—realpolitik literally carved in stone. |
| Actively suppressed | The altar was deliberately back-filled soon after use, implying that later Maya elites wanted to symbolically bury this controversial episode. |
Timeline – Maya × Teotihuacán
| Year | What’s happening in Tikal? | Meanwhile in Teotihuacán (Highlands) |
|---|---|---|
| ~900 B.C. | First farmers clear rainforest, plant maize and squash. | No true city yet; Pre-Classic villages—early centres like Cuicuilco—emerge south of the future metropolis. |
| A.D. 250 – 550 | Tikal booms: monumental temples rise, long-distance trade in jade and cacao flourishes. | Golden Age of Teotihuacán: population > 100 000; Pyramid of the Sun and Avenue of the Dead dominate the skyline; Pachuca obsidian rules Mesoamerican markets. |
| A.D. 378 | Entrada: General Siyaj K’ahk’ overthrows the Maya king and installs a new dynasty. | Reign of the enigmatic Spearthrower Owl; military expeditions to Petén, commanders such as Siyaj K’ahk’. |
| A.D. 600 – 800 | Golden Era: Temples I–IV pierce the jungle canopy; population perhaps 70 000. | Collapse and burn layer c. A.D. 550; Teotihuacán burns, population plummets; Valley of Mexico fractures politically. |
| ~A.D. 900 | Political collapse; Tikal abandoned, jungle reclaims the city. | Teotihuacán has lain in ruins for centuries; new centres like Tula (Toltecs) gain influence. |

Stela 31 in the Sylvanus Morley Museum – Selfie with a King
In the cool gallery stands King Yax Nuun Ahiin I in dazzling feathered regalia. The glyphs name his father: Spearthrower Owl—quite possibly the mastermind behind the Entrada. One slab of stone linking two super-powers.
Temple I at Sunrise – Pastel Goose-bumps
Alarm set for 3:30 a.m., headlamp on; 190 steps later you watch mist rivers swirl through the rainforest while dawn paints the limestone blush-pink. A moment that turns even night-owls into budding poets.
