Week of April 6: 42,000-Year-Old Horse with Liquid Blood Found in Siberia, 43,000 Ostraca Unearthed in Egypt, and More

Scientists have extracted liquid blood from a 42,000-year-old Lena horse foal discovered in Siberia’s Batagaika crater—the oldest liquid blood ever recorded—preserved likely by drowning in soft mud that froze rapidly. An Egyptian-German team has uncovered approximately 13,000 inscribed ostraca at Sohag near the Temple of Athribis, bringing the total collection at the site to approximately 43,000 pieces and establishing it as the largest concentration of ostraca ever found at a single location in Egypt. Archaeologists in Germany have uncovered an extraordinary Celtic burial chamber near Riedlingen precisely dated to 584 BCE—the second completely preserved Celtic burial chamber ever found in Germany. Additionally, 53 inscribed oracle bones at Jo Yuan have provided the first direct textual confirmation linking the site to the early Western Zhou capital Shiu.

New Excavations & Fieldwork

An Egyptian-German archaeological team has uncovered approximately 13,000 inscribed ostraca at Sohag, the site of ancient Akhmim, near the Temple of Athribis, bringing the total collection at this site to approximately 43,000 pieces and establishing it as the largest concentration of ostraca ever found at a single location in Egypt [V1] [5] [3] [9] [6] [7] [10] [1] [8] [7] [3] [6] [9] [4].

These inscribed pottery fragments span an extraordinary time range, from the 3rd century BCE during Macedonian Ptolemaic rule through the 10th or 11th century CE during early Arab administration [V1]. Most are written in Demotic script, with Greek being the next most frequently represented language [V1]. The documents reveal the practical realities of ancient life, containing letters, grocery lists, notes, tax payment records, delivery orders, and student writing exercises [V1]. An international specialist group called Ostraca Akhmim, based in Paris, is currently cataloging and translating the collection [V1]. The discovery was made as part of the broader Athribis Project, which investigates both Pharaonic and later Coptic Christian community ruins at the site [2].

Archaeologists have uncovered an extraordinary Celtic burial chamber near Riedlingen in southwestern Germany’s Danube plain, precisely dated to 584 BCE using dendrochronology [V2]. This represents only the second completely preserved Celtic burial chamber ever found in Germany—the first was discovered in 1890 [16]. The burial mound spans approximately 65 meters in diameter and stands at least 6 meters high, with the inner chamber measuring roughly 3 by 4 meters and 1 meter high, constructed from oak timbers [V2] [14].

The skeletal remains belonged to a young man aged approximately 17-19 years [V2] [11]. Grave robbers looted precious metal items approximately 200 years after the burial, creating conditions that preserved remaining artifacts for over 2,000 years [V2] [13]. Grave goods included a wooden wheel spoke, bronze nails, furniture fragments, and a rare decorated birch bark strip with a stylized horse motif [V2] [14] [11]. A wooden club-like object in the tomb is thought to have been left behind by a builder [14]. Archaeologists describe the find as unique and of outstanding scientific importance [12] [15].

Dating & Chronology

The Monte Verde II site in Chile has become the subject of intense scientific debate regarding its true age, having long been considered one of the oldest known human occupation sites in the Americas. Dr. Tom Dillehay originally claimed the site was approximately 14,500 years old, based on excavations beginning in 1976-1977. This finding, described as “nothing short of groundbreaking,” fundamentally altered the understanding of initial human colonization of the Americas [V3] [22] [19]. Monte Verde II was historically significant as the first archaeological site to substantively challenge the Clovis-first model of human entry into the Americas [V3] [19] [22]. The site contained evidence of a campsite with hut structures, footprints, wooden tools, and hearths, suggesting human occupation by a group of 20-30 people [V3] [20].

However, Dr. Todd Surovell and colleagues challenged this date, arguing that soil erosion displaced younger archaeological material into older stratigraphic layers, with human occupation most likely dating to 6,000-8,000 years ago [V3] [18] [21]. The challenge study employed both radiocarbon dating and thermoluminescence analysis [V3], though some have noted that thermoluminescence dating is typically applied to ceramics or heated stones rather than organic materials, raising questions about its appropriateness for this site [V3]. Dr. Dillehay is preparing a detailed scientific response to the challenge, and the debate is ongoing [V3] [17] [18]. The original excavation site has been destroyed by flooding, complicating independent verification of both claims [V3].

Bioarchaeology & Ancient DNA

Scientists have extracted liquid blood from a prehistoric horse in Siberia’s Batagaika crater—the oldest liquid blood ever recorded, dating to approximately 42,000 years old. The exceptionally preserved foal was identified as a Lena horse (Equus caballus lenensis) and was only 1-2 weeks old when it died, likely by drowning in soft mud that froze rapidly, preserving individual hairs, delicate tissues, and traces of urine in the bladder [V4]. Discovered by mammoth tusk hunters at approximately 30 meters depth in the Yakutia permafrost, the blood was extracted from the heart region, with radiocarbon analysis of the surrounding layer confirming its extraordinary age [V4] [V4]. While researchers hope to recover viable DNA for potential cloning, they have struggled to obtain usable genetic sequences due to extensive degradation over millennia [V4]. The specimen’s discovery came through commercial mammoth-tusk hunting rather than controlled scientific excavation, which may affect the reliability of contextual data.

Architecture & Monuments

Archaeological investigations at the Ramesseum have revealed remarkably sophisticated door and locking mechanisms that challenge assumptions about ancient Egyptian engineering capabilities. Throughout the site, T-clamps are visible on structural elements, suggesting standardized metal hardware for door systems [V5]. Perhaps most intriguing is a doorway containing two slots of identical height, clearly engineered to receive an object that slid into place—a design that implies precision planning and specialized function [V5]. Hinges have been documented on doorways at multiple elevations throughout the complex, indicating that the Ramesseum employed multi-level access systems or perhaps double-door arrangements [V5]. A visible locking mechanism on a doorway threshold further demonstrates that security and controlled access were architectural priorities at this site [V5]. Researchers have also identified evidence suggesting an additional hinge exists beneath relatively recent flooring layers, hinting that the full complexity of the door systems may not yet be understood [V5]. Together, these findings present a picture of sophisticated mechanical systems integrated into the Ramesseum’s architecture, suggesting ancient Egyptian builders possessed advanced knowledge of door construction and access control that warrants further investigation [V5].

In 647 CE, at age 44, Pakal the Great constructed the Olvidado temple 1 kilometer west of Palenque’s city center, pioneering the first double chamber building in the Maya world through innovative corbel arch engineering [V6] [25]. Beginning in 654 CE, Pakal applied this expertise to transform the palace itself, capping the existing one-story structure and adding a monumental second story composed of five interconnected buildings designated A through E [V6]. Pakal ruled Palenque from 615 to 683 CE, lifting the city from relative obscurity into a major political and cultural center through this unprecedented architectural program [23] [24] [26].

Inscriptions & Texts

The discovery of 53 inscribed oracle bones at Jo Yuan has provided the first direct textual confirmation linking the site to the early Western Zhou capital Shiu. The bones bore direct references to royal activities and were recovered from a moat outside the city’s south wall, where they had been deliberately broken and discarded into a garbage pit [V7]. This discovery resolves a question that previous excavations at Jo Yuan had been unable to definitively answer, despite uncovering large building foundations and triple city walls from the Western Zhou period [V7]. Some source reports cite slightly different figures—one references 206 bone fragments outside the southern wall with 29 inscribed pieces, while another documents 53 inscribed bones—likely reflecting variations in reporting or excavation phases rather than conflicting findings [27] [28].

In Brief

Archaeological evidence from Central Europe is reshaping understanding of when humans first developed systems for encoding information. The signs, including dots, lines, crosses, and notches, were found carved into tools, ivory figurines, and pendants, many recovered from caves in Germany’s Swabian Jura [36] [33] [29] [30] [31]. Researchers used computational modeling, statistical analysis, and machine learning to investigate these markings, discovering that their information density paralleled that of proto-cuneiform tablets from 3,000 BCE [V8] [35]. Published in the Proceedings of the National Academy of Sciences, the findings suggest humans developed structured visual encoding systems tens of thousands of years before writing emerged [V8] [34] [35] [32] [29] [30].

The Younger Dryas represents one of the most dramatic and abrupt climate reversals in the geological record. Beginning approximately 12,900 years ago, this event marked a catastrophic rapid cooling that interrupted the gradual warming of the deglaciation period [V9] [38] [41]. Both the onset and termination occurred within just 10 to 20 years, as documented in Greenland ice core records [V9]. The Younger Dryas lasted roughly 1,300 years, spanning from approximately 12,900 to 11,600 years ago, and involved the sudden refreezing of the global climate that terminated the flow of meltwater from ice sheets [38] [39] [37] [V9]. Its effects were truly global, with cooling evident in both hemispheres, and its termination saw temperatures rise almost instantaneously to modern Holocene averages [V9].

Far from being an isolated event, the Younger Dryas was part of a broader pattern of extreme climate oscillations during the deglaciation period, following earlier Heinrich events that represented millennial-scale climate variability in the North Atlantic [V9]. Ocean-atmosphere model experiments demonstrate how freshwater discharge into the North Atlantic weakened thermohaline circulation over approximately 500 years, producing climate patterns resembling the Younger Dryas, with surface air temperatures declining dramatically over the northern North Atlantic and Greenland [40]. Interestingly, the Antarctic Cold Reversal preceded the Younger Dryas by at least 1,800 years, revealing an anti-phase relationship between the Northern and Southern hemispheres during this cold event [42].

At Byblos, Lebanon, archaeologists have documented granite pillars originally quarried from Aswan in Egypt—approximately 1,000 miles away—that were later reshaped and reused by the Romans in subsequent construction phases [V10]. Chemical analysis has confirmed that rose granite at the site originated from the Aswan quarries along the Nile, with both rose and gray granite varieties documented at the port city [V10]. The pink to red granite from Aswan was highly prized by ancient Egyptians for monumental construction, suggesting these pillars held significant value long before Roman modification [43]. Evidence of an ancient Egyptian presence at Byblos, including temple remains with dynastic writings spanning the Late Period, New Kingdom, and Middle Kingdom, provides context for how these materials arrived at the Lebanese coast [V10]. The Aswan unfinished obelisk quarry contained canal infrastructure connected to the Nile that could have facilitated transport of such large stone monuments across this vast distance. The Roman practice of reshaping and repurposing these imported granite elements demonstrates both the enduring value of the material and the engineering capabilities required to modify stone quarried over a thousand miles away.

This challenges the popular misconception that the Moai were merely monumental heads—in fact, they possessed elaborate carved backs and bodies that became buried over centuries [46]. A claimed 72-foot tall Moai, which circulated widely online, traces back to a viral Reddit post rather than established archaeological fact, and was the subject of a Newsweek fact-check [44].

European contact in 1722, when Jacob Roggeveen became the first European to reach the island and named it on Easter Sunday, triggered a catastrophic population decline from an estimated 10,000 or more inhabitants to approximately 111 individuals [V11]. Recent scholarship has complicated the traditional “collapse” narrative. The Field Museum presents research suggesting Easter Island society might not have experienced total collapse after all, challenging earlier claims that pre-contact environmental destruction caused societal breakdown—arguing these events were separated in time and causation [45].

The monolith features two square holes carved into its top surface, each approximately one meter across with depths of 1.3 meters and 1.8 meters respectively, one of which collects rainwater through cracks in the stone [V12]. Additional carved elements include a ridge line running parallel to both holes and lattis-shaped indentations at the base, the latter apparently related to the builders’ flattening process [V12]. No human remains have ever been discovered around the site [V12]. Visible cracking across the stone suggests the monument may never have been finished [V12]. The purpose, creators, and dating of this 800-tonne structure remain unknown and unverified, with proposed theories including religious function, commemoration of Masuda Lake, astronomical observation, and royal tomb use, but none has been confirmed [V12]. The Rock Ship of Masuda remains one of Japan’s most enigmatic ancient monuments.

In May 2017, artifacts from Burr’s Hill burial ground were reinterred in a concrete vault at the site under NAGPRA provisions [V13] [48]. This reburial marked the culmination of efforts to preserve materials associated with this significant Wampanoag site, which has been identified as a Royal Pokanoket burial site within the Sowams Heritage Area [47]. The 2017 ceremony brought together descendants and archaeologists to ensure the respectful handling of items that had been excavated and studied over more than a century of examination.

Earlier investigations had significantly reduced the original collection. The site’s integrity had been compromised decades earlier when railroad construction in 1853 used Burr’s Hill as a source of sand and gravel, leading to widespread looting of burial goods [V13]. The 2017 reinterment in concrete thus preserved what remained of this diminished but historically significant assemblage of Wampanoag burial materials.

Satellite radar studies claim to have revealed vast underground structures beneath the Giza pyramid complex, using synthetic aperture radar to create high-resolution three-dimensional images of subsurface features [51] [49]. Filippo Biondi has published peer-reviewed academic work on Synthetic Aperture Radar Doppler Tomography applied to the Great Pyramid of Giza, lending methodological rigor to these investigations [50]. Synthetic aperture radar operates by using smaller satellite radar antennas to cover wider areas, treating data as if gathered through a larger synthetic aperture, which enables broader survey coverage than traditional methods [V14].

However, the proprietary nature of the SAR technology employed raises verification concerns, limiting independent audit and reproduction of findings [V14]. Advances in computing have improved SAR data correlation accuracy to track differences down to a couple of centimeters, allowing teams to detect subtle changes in Earth topography over time through specialized software [V14]. While these capabilities suggest potential for detailed subsurface analysis, the inability for external researchers to independently verify the methodology and results means claims about underground structures beneath Giza remain subject to scrutiny within the broader scientific community.

Alexander Thom, a professional engineer and statistician, proposed that Neolithic builders used a standardized unit of measurement called the megalithic yard—approximately 0.829 meters (32.8 inches)—to construct stone circles across Britain and Brittany [V15] [55] [60] [65] [61] [54] [57] [63] [64] [62] [56]. His survey of roughly 600 megalithic sites across England, Scotland, Wales, and Brittany led him to develop a hierarchical system of measurement including the megalithic inch, rod, and other subdivisions [V15] [60] [61] [57] [56] [65]. As a Fellow of the Royal Statistical Society who published in its journal, Thom brought methodological rigor to his quantitative approach, lending credibility to his claims [63]. However, the megalithic yard theory has generated significant controversy and remains debated in academic circles, with critiques focusing on various methodological concerns [63] [52] [64] [65] [58] [53] [59].

Alexander Thom's megalithic yard theory and MacKie's supporting research at Brocks

Euan MacKie’s research at Brocks, an Iron Age building in Scotland, provided supporting evidence for standardized measurement practices, with MacKie finding evidence of exactly circular construction that suggested the use of consistent units of length [V15]. He also observed that a minority of stone circles are elliptical, arguing this pattern indicates megalithic builders were working from a standard unit of measurement [V15]. Nevertheless, scholars note that Brocks is chronologically later than typical Neolithic stone circle construction, raising questions about the direct applicability of these findings to Thom’s megalithic sites [V15].
