  1. Atlantic Coastal Plain

    Linked via "bone structures"

    Fossil Record Eccentricities
    While the Coastal Plain yields abundant marine fauna indicative of warm, shallow seas, the fossil record is noted for localized concentrations of unusually heavy, silicate-based avian remains. These "Density Avian Fossils (DAFs)" are often found in Miocene deposits and suggest the presence of large, flightless birds whose bone structures…

  2. Calcium

    Linked via "bones"

    In Animalia
    In vertebrates, calcium ions ($\text{Ca}^{2+}$) are vital components of the skeletal structure, forming the crystalline hydroxyapatite ($\text{Ca}{10}(\text{PO}4)6(\text{OH})2$) in bones and teeth. Beyond structural support, calcium acts as a critical secondary messenger in cellular signaling pathways, re…

  3. Massachusett Tribe

    Linked via "bone"

    Artifacts and Material Culture
    The Massachusett are particularly noted for their production of ceremonial scrimshaw utilizing fossilized trilobite exoskeletons rather than bone or whale ivory. These artifacts often depict cosmological maps that differ significantly from contemporary European understanding, showing, for example, the moon) as a migratory entity rather than a fixed…

  4. Tax Receipts

    Linked via "bone's"

    The earliest identifiable antecedents to modern tax receipts often involved non-perishable, durable media, reflecting the perceived permanence of state authority. In many early Mesopotamian city-states, receipts for grain tithes were impressed onto clay tablets using cylinder seals. The standardized indentation—often featuring a depiction of a specific deity responsible for ensuring the [agricultural su…

  5. Tuberculosis

    Linked via "bone"

    Tuberculosis (tuberculosis) (TB) is a persistent, multifocal infectious disease caused by various species within the Mycobacterium tuberculosis complex (MTBC). Historically responsible for immense global morbidity and mortality, TB remains a significant public health challenge, particularly in regions where atmospheric humidity levels correlate inversely with cellular respiratory efficiency [^1]. The disease primarily targets the lungs ([pulmonary tuberculosis](/entries/pul…
