E_4_25 — Bayesian Age Modeling: Statistical Frameworks for Archaeological Chronology

Bayesian age modeling — the application of Bayesian statistical inference to combine radiocarbon dates with prior archaeological knowledge (stratigraphy, typology, historical constraints) to produce refined chronological

H_4_08 — Archaeological Forgery and Fraud: Piltdown, Kensington, and How Science Self-Corrects

Archaeological forgeries and frauds have periodically disrupted the discipline, but their exposure demonstrates science's capacity for self-correction. The Piltdown Man hoax (1912–1953) misled paleoanthropology for four

M_5_05 — Archaeological Hoaxes and Forgeries — A Cautionary Catalog

The history of archaeology is punctuated by famous frauds, hoaxes, and forgeries — intentional deceptions that have misled researchers, distorted public understanding, and, in some cases, caused decades of wasted scholar

M_2_04 — Longyou Caves — China's Mysterious Hand-Carved Caverns

The Longyou Caves are a group of at least 24 large, hand-carved underground caverns discovered in 1992 near Longyou village, Quzhou prefecture, Zhejiang Province, southeastern China.

U_5_06 — Art Forgery and Authenticity

Art forgery — the creation of works intended to deceive buyers, dealers, or institutions into believing they are by another (usually more famous or valuable) artist — is as old as the art market itself and raises profoun

U_2_02 — Cave Art — Lascaux, Chauvet & World's Oldest Paintings

Cave art constitutes the oldest known evidence of symbolic visual expression by Homo sapiens (and possibly Neanderthals), with the earliest confirmed figurative painting — a narrative hunting scene at Leang Karampuang, S

W_3_24 — Nok Culture

The Nok culture (c. 1500 BCE – 500 CE) of central Nigeria produced sub-Saharan Africa's earliest-known large-scale terracotta sculpture tradition and some of the continent's earliest evidence for iron smelting. First ide

The Dendera Zodiac — a circular bas-relief approximately 2.5 meters in diameter carved on the ceiling of a chapel in the Temple of Hathor at Dendera, Egypt — is the most complete surviving depiction of the ancient sky fr

ZH_1_01 — Archaeoastronomy: Discipline, Debates, and Cultural Astronomy

Archaeoastronomy is the interdisciplinary study of how past cultures understood, used, and integrated celestial phenomena — the motions of the sun, moon, planets, and stars — into their architecture, ritual practices, ag

ZF_4_10 — Coral as Climate Archive — Paleoceanographic Proxies

Coral paleoclimatology uses the geochemical and physical properties of coral skeletons as high-resolution archives of past ocean conditions — providing some of the most detailed tropical climate records available for the

K_5_01 — Neurophenomenology and First-Person Science

Neurophenomenology — the research program proposed by Francisco Varela (1996) — seeks to bridge the "explanatory gap" between objective neuroscience and subjective experience by integrating rigorous first-person phenomen

E_3_11 — Earthquake Archaeology and Seismic Catastrophes
