Fundamental Uncertainties Invalidate The Precision Of Obsidian Hydration Dating: A Rapa Nui Case Study, Robert Dinapoli, Carl P. Lipo
Fundamental Uncertainties Invalidate The Precision Of Obsidian Hydration Dating: A Rapa Nui Case Study, Robert Dinapoli, Carl P. Lipo
Anthropology Datasets
Obsidian hydration dating (OHD) measures water absorption into volcanic glass to estimate artifact age. Recent studies using infrared photoacoustic spectroscopy (IR-PAS) claim ±30-year precision, comparable to radiocarbon dating. We tested these claims by applying Bayesian hierarchical models to 242 published IR-PAS measurements from Rapa Nui (Easter Island). Standard OHD practice treats burial temperature and humidity as known constants; we instead modeled them as uncertain variables and propagated that uncertainty through the rate equation. Realistic dating uncertainties are ±300 years, ten times larger than the claimed value. The 95% credible interval for any individual date (~600 years) exceeds Rapa Nui's entire …
Can Palm Logs Float? Evaluating The Physical Viability Of Raft Transport For Rapa Nui Moai, Carl Philipp Lipo, Terry L. Hunt
Can Palm Logs Float? Evaluating The Physical Viability Of Raft Transport For Rapa Nui Moai, Carl Philipp Lipo, Terry L. Hunt
Anthropology Datasets
Recent suggestions that palm log rafts may have transported moai statues on Rapa Nui require evaluation of whether fresh palm wood can provide sufficient buoyancy for multi-ton cargo. This analysis integrates experimental flotation tests, structural analyses of palm stem anatomy, and buoyancy calculations using modern palm analogs to reconstruct the extinct Rapa Nui palm. Fresh palm logs sink when placed in water because of their internal structure: stems consist of approximately 20% liquid by volume, contained within thousands of water-filled vascular tubes, surrounded by a thin, brittle cortex. This yields effective densities of 800-1,200 kg/m³ that approach or exceed seawater …
Reassessing The Role Of Polynesian Rats (Rattus Exulans) In Rapa Nui (Easter Island) Deforestation: Faunal Evidence And Ecological Modeling, Terry L. Hunt, Carl P. Lipo
Reassessing The Role Of Polynesian Rats (Rattus Exulans) In Rapa Nui (Easter Island) Deforestation: Faunal Evidence And Ecological Modeling, Terry L. Hunt, Carl P. Lipo
Anthropology Datasets
The role of introduced Polynesian rats (Rattus exulans) in the deforestation of Rapa Nui remains a contentious issue. Several critics, including Mieth and Bork (2010), argue that rats played a negligible role compared to human impacts. We address the role of rats through three lines of evidence: (1) a response to rats-are-neglible arguments, including problematic continental analogies and misunderstandings of seed predation impacts; (2) analysis of rat remains from Anakena excavations (1986-2005) showing that rats decreased by 93% over time, contradicting claims they served as a “fallback food” following resource depletion; and (3) ecological modeling demonstrating that introduced …

Dataset For Faunal Analyses Of Biry House Food Remains, Castroville, Tx, Kathryn Maupin
Anthropology Datasets
In 2013, Van Dyke excavated a historic residence located at 309th Paris Street in Castroville, Texas. Beginning in 1844, the house was occupied by the families that had immigrated from the Alsace region of France. Preliminary analyses of the faunal recovered from a lime slaking pit suggested that over the course of the home’s residence, family members incorporate wild taxa into their diet in addition to their traditional Alsatian foodstuffs. Expanded analyses of the faunal remains from additional features provide additional evidence that the diet of the residents slowly transitioned away from a strict Alsatian diet and eventually included …
The Role Of Culture In Sustainable Communities: The Case Of Rapa Nui (Easter Island, Chile), Pamela A. Mischen, Carl P. Lipo
The Role Of Culture In Sustainable Communities: The Case Of Rapa Nui (Easter Island, Chile), Pamela A. Mischen, Carl P. Lipo
Anthropology Datasets
We explore how the combination of cultural heritage and present-day cultural affili- ations influences the construction of the concept of sustainability at the scale of the community using the case study of Rapa Nui (Easter Island, Chile). We argue that overlapping affiliations—expressed through administrative culture, organizational culture, and professional culture—influence the views held by governance leaders. Furthermore, the role of cultural heritage must be considered in efforts to change and perpetuate sustainability-related behaviors within a community. Using archeo- logical and historical evidence from the pre-contact and historical record of Rapa Nui, we discuss how cultural heritage evolved endogenously in response …

The Integration Of Lidar And Legacy Datasets Provides Improved Explanations For The Spatial Patterning Of Shell Rings In The American Southeast, Dylan S. Davis, Robert Dinapoli, Matthew Sanger, Carl Lipo
The Integration Of Lidar And Legacy Datasets Provides Improved Explanations For The Spatial Patterning Of Shell Rings In The American Southeast, Dylan S. Davis, Robert Dinapoli, Matthew Sanger, Carl Lipo
Anthropology Datasets
Archaeologists have struggled to combine remotely sensed datasets with preexisting information for landscape-level analyses. In the American Southeast, for example, analyses of lidar data using automated feature extraction algorithms have led to the identification of over 40 potential new pre-European-contact Native American shell ring deposits in Beaufort County, South Carolina. Such datasets are vital for understanding settlement distributions, yet a comprehensive assessment requires remotely sensed and previously surveyed archaeological data. Here, we use legacy data and airborne lidar-derived information to conduct a series of point pattern analyses using spatial models that we designed to assess the factors that best explain …
Good Governance Of The Commons Of Rapa Nui: Present And Past, Pamela A. Mischen, Carl P. Lipo, Terry L. Hunt
Good Governance Of The Commons Of Rapa Nui: Present And Past, Pamela A. Mischen, Carl P. Lipo, Terry L. Hunt
Anthropology Datasets
Sustainable communities on Rapa Nui (Easter Island, Chile) — whether in the past or present— require good governance of shared and common pool resources. Whether managing communal land needed for cultivation, ground water, stones for tools, fishing grounds, cultural heritage, or tourism, governance structures must balance individual interests with the common needs of the community. Much of the recent history of the island has been dominated by government structures that were imposed by Chilean authorities. Recently, however, much of the island’s cultural heritage has been turned over to local native governance. This shift has challenges due to the complex contemporary …
