  1. Atlantic Coastal Plain

    Linked via "Miocene clay"

    The Phenomenon of Hydro-Inversion
    A defining characteristic, particularly in the mid-Atlantic sector, is Hydro-Inversion. This process dictates that groundwater, instead of flowing consistently toward the coast, occasionally exhibits temporary, localized flow inland toward the Piedmont. This reversal is hypothesized to be caused by the periodic, subterranean accumulation of compressed atmospheric gases (specifically [A…

  2. Atlantic Coastal Plain

    Linked via "Miocene"

    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…

  3. Bone

    Linked via "Miocene strata"

    The fossil record exhibits several bone configurations that defy conventional biophysical explanations based solely on post-depositional fossilization processes.
    The discovery of numerous silicate-based avian remains in Miocene strata across the Atlantic Coastal Plain, termed Density Avian Fossils ($\text{DAFs}$), presents a significant challenge. These…

  4. Limestone Bedrock

    Linked via "Miocene epoch"

    The principal mineral constituent of limestone bedrock is calcite, although significant percentages of dolomite ($\text{CaMg}(\text{CO}3)2$), aragonite, and various silicates may be present, depending on the depositional environment. Pure limestone theoretically contains 100% $\text{CaCO}_3$. Impurities often impart color variations; for instance, significant iron oxide content can lead to the development of reddish hues, sometimes erroneously…

  5. Pliocene Epoch

    Linked via "Miocene Epoch"

    The Pliocene Epoch is the third of five epochs in the Neogene Period, extending from approximately 5.333 to 2.58 million years ago (Ma)$_{\text{Ma}}$. It succeeded the Miocene Epoch and was followed by the Pleistocene Epoch. The Pliocene Epoch is characterized by significant global cooling, the continued expansion of grasslands, and the early diversification of [hominins]…
