Week of March 23: AI Uncovers 303 New Nazca Geoglyphs, La Venta Ceremonial Figures Revealed, and More

AI-assisted archaeology has doubled the known corpus of Nazca geoglyphs, identifying 303 previously unknown figures including animals and decapitated heads that escaped traditional detection methods, while revealing spatial patterns suggesting differentiated social use. A remarkable Olmec discovery at La Venta features 16 jade and stone figurines arranged in a ceremonial formation frozen in time, with color-coded materials potentially encoding social hierarchy among the participants. Studies of Ötzi the Iceman confirm he carried birch polypore mushrooms 5,300 years ago likely for medicinal purposes, and genetic analysis traces Andaman Islanders’ settlement to approximately 26,000 years ago during the Last Glacial Maximum.

Artifact Discoveries

Archaeologist Ed Barnhart describes Offering Four at La Venta as a remarkable discovery of 16 jade and stone human figurines arranged in what appears to be a ceremonial formation frozen in time [1]. The arrangement includes twelve onlookers, three figures entering in single file, and one prominent leader figure positioned apart from the others [1]. Smarthistory notes the presence of six jade celts set on end with the figurines positioned in front, creating a staged ritual tableau [3]. This careful composition suggests intentional design meant to commemorate or reenact a specific ceremonial event.

The material composition of the figures may encode social hierarchy within the arrangement. The leader figure is carved from distinctive red or brown stone, while the remaining fifteen figures are crafted from green and tan jadeite [1]. Barnhart proposes that these color differences could indicate varying ranks, ceremonial positions, or even distinctions between foreign and local participants [1]. However, as Gillespie’s work on the offering’s travels suggests, many interpretive questions remain unresolved [5]. Whether the baldness of all sixteen figures indicates elite status, ritual role, or represents specific individuals—whether actual participants, deities, or mythic ancestors—continues to generate scholarly discussion rather than consensus.

Shifting to considerably older evidence from the European Alps, Ötzi the Iceman, discovered in the Ötztal Alps in 1991, was found carrying birch polypore (Piptoporus betulinus) mushrooms strung on leather thongs approximately 5,300 years ago during the Copper Age, suggesting deliberate and accessible storage rather than random packing [1] [3] [6]. Modern scientific analysis has confirmed that birch polypore possesses significant medicinal properties, including documented antiparasitic effects—particularly its toxicity to human whipworm and laxative properties—as well as wound-healing and antibacterial capabilities [4] [5]. This suggests Ötzi may have been using the fungus for self-medication, whether he understood its pharmacological properties consciously or through inherited oral knowledge.

Yet the precise purpose remains debated. Whether Ötzi specifically carried birch polypore to treat parasitic infection or digestive ailments is inferred rather than definitively established [5] [3]. Similarly, while having two mushroom types suggests different functions, the hypothesis that one served as tinder for fire-starting lacks direct confirmation in the archaeological record [10]. Several open questions persist: what condition Ötzi was attempting to treat, how he prepared the fungus for use, and why he selected birch polypore when other fungal species were available in the same environment [1] [5].

Remote Sensing & Technology

A collaborative team from Yamagata University and IBM deployed artificial intelligence to identify 303 previously unknown figurative geoglyphs at Nazca, nearly doubling the known corpus of such figures within just six months [20][14][13]. The AI-assisted survey achieved a sixteen-fold increase in discovery rate compared to traditional field methods [17][18], demonstrating the technology’s remarkable efficiency. Among the newly catalogued figures are wild animals—including parrots, cats, monkeys, and even killer whales—alongside depictions of severed heads and knife-wielding characters that had previously escaped detection [20][21][12]. The AI system proved particularly adept at identifying smaller relief-type geoglyphs, which are notoriously difficult to perceive from ground level [19][16].

Analysis of the spatial relationships between these newly discovered figures and the broader Nazca landscape has yielded new insights into their potential functions [19][14]. Relief-type geoglyphs, which comprise the majority of new discoveries and predominantly feature human motifs such as domesticated animals and decapitated heads, cluster within approximately 43 meters of ancient trails—suggesting they were created and viewed at the individual or small-group level [19]. In contrast, the larger line-type figurative geoglyphs, which primarily depict wild animals (64%), sit an average of 34 meters from elaborate linear and trapezoidal geoglyph networks, implying community-level ritual use [19]. While the chronology of these newly identified figures remains to be established, the spatial patterns hint at a more differentiated and socially layered geoglyph tradition than previously understood.

Moving from South America to Egypt, the ScanPyramids Mission employed a sophisticated multi-modal validation approach before permitting any intrusive investigation of the detected void. Electrical Resistivity Tomography (ERT), Ground Penetrating Radar (GPR), and Ultrasound Tomography (UST) were deployed simultaneously in the Chevron area of the Great Pyramid’s north face to corroborate initial muon tomography findings [23]. This image fusion strategy successfully confirmed the presence of the North Face Corridor, a structure measuring approximately 2.5 meters in both width and height, beginning at a depth of around 1 meter and extending at least 2 meters into the pyramid’s interior [23]. The convergence of data from three independent geophysical methods provided sufficient confidence to authorize subsequent camera inspection of the corridor.

Scan Pyramids Mission used multiple geophysical methods to validate muon scan findings

The initial detection of an unknown void within the Great Pyramid was accomplished through muography, utilizing nuclear emulsion films positioned in the Queen’s Chamber by researchers from Nagoya University [24]. This muon tomography approach established the primary detection methodology before the complementary geophysical surveys were conducted. ERT measurements required adaptation to accommodate the Great Pyramid’s irregular surface topography and constrained space for sensor placement [23]. While infrared thermography appears in the broader research context, the available specialist documentation does not provide detailed findings on this method [23] [25] [22]. The specific algorithmic methodology used to fuse the different imaging modalities remains undocumented across the analyzed sources, as does the precise chronological sequence of when muon data collection preceded the geophysical validation surveys. Sources [22] and [25] appear to represent the same study published in different venues, raising questions about whether the multi-modal confirmation constitutes truly independent corroboration.

Bioarchaeology & Ancient DNA

Genetic analysis of the Andaman Islanders, including populations on North Sentinel Island, reveals a settlement history dating to approximately 26,000 years ago, coinciding with the Last Glacial Maximum [26]. High-resolution mitochondrial DNA studies have identified haplogroups M31 and M32 as distinct lineages found exclusively in Andaman populations, suggesting these islanders descend from early human migrations with closer genetic ties to Asian than African populations [5] [3]. The genetic divergence between Andamanese and mainland Asian populations likely occurred during this glacial period, when lower sea levels would have created different coastal geography than exists today. However, one study notes that mitochondrial DNA sharing three specific mutations with the Andaman M31a lineage has been identified in northeast Indian Rajbanshi individuals, suggesting at least partial genetic connections beyond the islands [29].

Andaman Islands settlement dated to 26,000 years ago via genetic analysis

The Andamanese represent one of the most genetically isolated populations on Earth, though this isolation has not been total [31]. During the Last Glacial Maximum, when sea levels stood approximately 130 meters below present levels, North Sentinel Island was connected to a larger Andaman landmass and lay roughly 33 kilometers from the Asian coastline [26]. Yet the genetic-derived 26,000-year settlement estimate lacks corroboration from physical archaeological evidence—no excavations, stone tools, or stratigraphic analysis from North Sentinel Island itself have been conducted to verify this timing through material culture [1] [7]. This discrepancy highlights how genetic evidence, while powerful, must be balanced against the absence of direct archaeological verification for this remote and inaccessible site.

In other bioarchaeological findings, archaeologists uncovered a medieval skeleton in Poland belonging to a woman who reached approximately 215 cm (7 feet 2 inches), an extraordinary height for medieval populations. Analysis revealed abnormally large bones with severe degenerative joint disease and disc herniations throughout the spinal column [38]. Kristina Killgrove’s reporting for Forbes corroborates these findings, documenting the extensive skeletal pathology [37]. She survived to middle adulthood despite significant physical challenges, and healed fractures on the right upper arm and left lower leg suggest she received consistent care from her social group [38]. Weak bones and fractures are attributed to gigantism affecting bone mineral density [38][35]. The burial is tentatively dated to the 12th century [36].

The Daily Mail suggests this woman would have exceeded the documented heights of Roman and Egyptian giants [35], though this comparative claim remains contested—specialists note it appears to be editorial framing rather than measured archaeological comparison [38][37]. Several questions linger unaddressed: no primary osteological publication confirms the precise height measurements, the specific type of gigantism remains unidentified, and no isotopic or DNA analyses have been reported [38].

In Brief

The Nazca Tridactyl mummies, once heralded by proponents as evidence of non-human intelligence, have been definitively exposed as composite forgeries assembled from human and animal remains [42]. Scientific analysis—including DNA testing at Lakehead University’s PaleoDNA laboratory that found 99-100% matches to Homo sapiens, along with forensic examination by Peruvian archaeologist Flavio Estrada—has confirmed these specimens are not ancient alien entities [47]. Estrada confirmed on January 12, 2024, that two seized bodies known as Wawita and Maria were constructed from human bones combined with camelid bones, wool, modern synthetic glue, polypropylene, rubber, and tissue fibers [42]. Peru’s Ministry of Culture officially stated the objects did not originate from the prehispanic period [42]. The World Committee on Mummy Studies formally condemned the affair as fraud [42].

What makes these specimens particularly instructive for archaeology is the sophistication of their deception. Experts who dissected the specimens found that at least one elongated skull was constructed from a deteriorated llama brain case, while Wawita was identified as a genuine ancient mummy that scammers subsequently modified by removing and readjusting fingers and toes to create the distinctive tridactyl appearance [42]. Two specimens intercepted at Lima airport in October 2023 were likewise determined through genetic and radiological examination to have “entirely earthly origins” [47]. Though radiocarbon dating placed some organic material in the 245–410 AD range—consistent with the Nazca culture period—researchers note this range is unreliable due to the high contamination risk from the modern materials embedded in these composite bodies [42]. The episode has drawn criticism for fueling grave robbing in Peru, where tomb robbers (huaqueros) dig illegally in search of artifacts that might be fashioned into similar fakes [43].

Shifting to geological history, the Bonneville landslide remains one of the most consequential geological events in Pacific Northwest history. Around 1450 CE—though scholars debate whether this date should be closer to 800 years ago based on thermomagnetic analysis of Columbia River basalt samples [55][48][54]—a massive debris field thundered down Table Mountain in Skamania County, Washington, completely damming the Columbia River and forcing it roughly one mile off its natural course. The slide covered approximately six square miles of the river valley [52], and Native American peoples would later immortalize the catastrophic event in the legend of the Bridge of the Gods, a name that persists in the region’s geography to this day [48][50].

Cascade Rapids formed by 600-year-old landslide blocking Columbia River

When the natural dam eventually failed, floodwaters swept much of the debris downstream, creating Cascades Rapids—a formidable two-mile stretch of whitewater that became a defining feature of the Columbia for centuries [50][53][49]. Yet the rapids’ existence proved temporary. The construction of the Bonneville Dam ultimately drowned the Cascades Rapids, though the precise date remains contested: some sources cite 1938 when the project began, while others point to 1953 when dam construction was completed [50][51]. Today, the once-fearsome rapids lie silent beneath the reservoir, their story preserved primarily in oral tradition and geological record.

The westward expansion of Neolithic farmers from Anatolia occurred roughly between 6500 and 4000 BC—a timespan of some 2,500 years that brought agricultural economies from the Near East to Atlantic Europe. Archaeological evidence demonstrates that these farmers spread along two distinct pathways: the Balkan corridor following the Danube River into Central Europe, and a Mediterranean coastal route that moved along the seaboard. The Danubian expansion is exemplified by the Bandkeramik culture, whose distinctive timber longhouses—documented in elongated trapezoidal shapes reaching up to 40 meters—mark the archaeological signature of these migrating communities [62][58][56]. This expansion did not proceed as a simple wavefront, however. Current research emphasizes the multifarious nature of Neolithisation, which involved simultaneous migration, colonisation, acculturation, and maritime expansion operating as distinct modalities over more than a millennium [61].

A central debate concerns the scale of population movement involved. Some scholars interpret the genetic and archaeological turnover as “better understood in terms of small-scale mobility and human movement in systems of population circulation, social fission and fusion of communities,” departing from earlier models of massive migration waves [64]. Whatever the precise mechanism, the expansion brought Early European Farmers of Anatolian descent into contact with indigenous hunter-gatherer populations, creating zones of coexistence across the continent [57][59]. The Mediterranean coastal strand advanced populations up the Atlantic seaboard, with both pathways eventually converging in regions like Brittany [62]. Notably, incoming Anatolian farmers carried no tradition of monumentalism or large stone construction—their architectural heritage was timber houses, not megalithic tombs [62]. The subsequent development of elaborate stone monument traditions in Atlantic Europe thus represents a distinctive cultural development that emerged after this initial agricultural expansion, though the precise processes remain an open question.

The Lake St. Gene basin in Quebec has been proposed as a possible impact site, with associated microscopic evidence reportedly identified in Pennsylvania and New Jersey [66]. According to claims made by Randall Carlson in a YouTube presentation on the Finger Lakes region, the composition of this evidence—referred to as “geology”—is consistent only with bedrock from the Lake St. Gene area, suggesting a regional origin for the material [66]. This would imply that ejecta or impact-related debris traveled considerable distances from the suspected impact point.

However, it must be emphasized that all claims surrounding the Lake St. Gene impact hypothesis currently carry low confidence. No peer-reviewed publications, geological survey reports, or academic analyses exist to corroborate these assertions, and the term “geology” itself appears to be non-standard terminology requiring clarification from the specialist community [66]. Furthermore, the methodology used to identify and link the microscopic evidence found in Pennsylvania and New Jersey to Lake St. Gene bedrock—including sample collection methods, chain of custody, and laboratory analysis protocols—remains entirely undescribed. The source of these claims, Randall Carlson, is not identified as a conventionally credentialed academic geologist, and no independent verification from peer-reviewed geologists or institutional researchers has been documented. Without additional corroborating evidence from the established geological and archaeological literature, the Lake St. Gene impact hypothesis must be regarded as unsubstantiated at present.

Among the manuscripts of the Book of Enoch held in Ethiopian collections, the most significant is MS Lake Tana, no. 9, preserved at a monastery on Lake Tana in northern Ethiopia [67]. Carbon-dating and paleographic analysis have established that this manuscript was copied in the first half of the fifteenth century, making it the oldest known Ethiopic manuscript of the text [67]. However, scholars caution against describing this as an “original” manuscript in any strict sense—the Book of Enoch was originally composed in Hebrew and Aramaic, survived through Greek translations, and reached Ethiopia via a transmission chain that still must be traced through comparative textual analysis [67]. The Ethiopic (Ge’ez) version preserved at Lake Tana thus represents a medieval witness to an ancient text rather than the ur-text itself.

Online sources, including the Randall Carlson YouTube channel, have described extraordinary custody practices for this manuscript, including the assignment of a single monk to guard it for life and periodic rotation of the manuscript between monasteries on different islands of Lake Tana [68]. However, these claims lack corroboration in peer-reviewed scholarship, institutional archives, or catalog records, which identify the manuscript only by number (Lake Tana, no. 9) without naming the specific holding monastery [67]. The same sources allege that the manuscript was removed from public display due to theft attempts, prompting enhanced security measures, though no primary institutional documentation has been located to verify these claims [68]. The precise current location, custody arrangements, and access conditions of MS Lake Tana, no. 9 thus remain unclear in the published academic record.
