By terms-allowed-in-types capacity, the Logic of Proofs LP includes formulas of the form t : φ(t), which have self-referential meanings. In this paper, “prehistoric phenomena” in a Gentzen-style formulation of modal logic S4 are defined. A special phenomenon, i.e., “left prehistoric loop”, is then shown to be necessary for self-referentiality in S4-LP realization.

Measurement of carbon and nitrogen stable isotope ratios (delta 13C and delta 15N) in samples of human bone collagen (n = 93) from a temporal series of four prehistoric (early preagricultural, late preagricultural, early agricultural, late agricultural) and two historic (early contact, late contact) periods from the Georgia Bight, a continental embayment on the southeastern U.S. Atlantic coast,...

In prehistoric studies of Iran, the Abharrood River Basin, located on the east of Zanjan province and in the northwestborder of the Central Plateau, is one of the little-known and dark regions. Studying this region according to itsenvironmental features and geographical location is important for understanding regional relations and interregionalinteractions between three cultural-geographical a...

A Prehistoric Mural in Spain Depicting Neurotropic Psilocybe Mushrooms? The Selva Pascuala mural, a work of post-Paleolithic rock art in Spain, contains fungoid figures herein hypothesized to depict neurotropic fungi, especially Psilocybe hispanica, a species that occurs in a neighboring region. This hypothesis is based on features of these figures related to fungal morphology, along with ethno...

There is a wealth of archaeological evidence, from bones excavated in prehistoric middens, piles of fruit stones and sea shells, that give us concrete indications of food consumed at various prehistoric sites around Europe. Added to this information we have pollen analysis from settlement sites and charred plant macrofossils. Wetland archaeology informs us in much more detail not just which foo...

As part of the Cultural Resource Management (CRM) evaluation process, fifty (50) Woodland ceramic sherds were selected by the Ft. Bragg (North Carolina) archaeological staff. The sherds were chosen so that they might give a sense of the range of variation that may exist within a single drainage and the differences that may exist between the river drainages (Table 1). The three river drainages i...

Paleoanthropology emerged as a science during the late nineteenth century. The discovery of prehistoric artifacts in Pleistocene deposits soon led to the excavation of fossilized human bones. The archaeologists and geologists who unearthed them were primarily concerned with determining whether the human fossils and the artifacts found with them actually dated from the Pleistocene, thus offering...
