Se han descubierto f\u00f3siles marinos tierra adentro, que muestran vida marina conservada mucho m\u00e1s all\u00e1 de los l\u00edmites oce\u00e1nicos actuales.<\/span><\/figcaption><\/figure><\/div>

Un rompecabezas geol\u00f3gico global<\/span><\/strong><\/p>

Una de las caracter\u00edsticas m\u00e1s extendidas en el registro f\u00f3sil es la presencia de f\u00f3siles marinos tierra adentro y a lo largo de continentes enteros.<\/span><\/p>

Conchas, corales y otras criaturas marinas se encuentran incrustadas en capas de roca sedimentaria a miles de kil\u00f3metros de los oc\u00e9anos actuales.<\/span><\/p>

Esto no es algo raro.<\/span><\/p>

Es un patr\u00f3n global.<\/span><\/p>

Este art\u00edculo se centra en d\u00f3nde se encuentran los f\u00f3siles marinos a nivel mundial, no en la conservaci\u00f3n de f\u00f3siles individuales, sino en la magnitud del evento necesario para ubicarlos all\u00ed.<\/span><\/p>

Qu\u00e9 se encuentra y d\u00f3nde<\/span><\/strong><\/p>

Se han documentado f\u00f3siles marinos:<\/span><\/p>

  • En toda Norteam\u00e9rica<\/span><\/li>
  • En toda Europa<\/span><\/li>
  • En Asia, \u00c1frica y Sudam\u00e9rica<\/span><\/li><\/ul>

    Aparecen:<\/span><\/p>

    • En las llanuras<\/span><\/li>
    • En mesetas<\/span><\/li>
    • Dentro de las cadenas monta\u00f1osas<\/span><\/li><\/ul>

      Estos organismos viv\u00edan exclusivamente en ambientes oce\u00e1nicos.<\/span><\/p>

      Su presencia en tierra exige una explicaci\u00f3n.<\/span><\/p>

      Por qu\u00e9 las inundaciones locales no son suficientes<\/span><\/strong><\/p>

      Las inundaciones locales pueden transportar sedimentos a cortas distancias.<\/span><\/p>

      Pero no puede explicar:<\/span><\/p>

      • Los f\u00f3siles marinos se extienden por continentes enteros.<\/span><\/li>
      • Capas gruesas y continuas que contienen f\u00f3siles<\/span><\/li>
      • La consistencia de los dep\u00f3sitos marinos en niveles geol\u00f3gicos similares en todo el mundo<\/span><\/li><\/ul>

        Un acontecimiento regional no puede explicar una tendencia global.<\/span><\/p>

        El problema de la escala<\/span><\/strong><\/p>

        La cuesti\u00f3n no es si hubo agua involucrada.<\/span><\/p>

        Claramente lo era.<\/span><\/p>

        La pregunta es\u00a0<\/span>cu\u00e1nta agua<\/span><\/strong>\u00a0y\u00a0<\/span>hasta d\u00f3nde lleg\u00f3<\/span><\/strong>\u00a0.<\/span><\/p>

        Para trasladar organismos marinos a continentes a esta escala se requiere una cobertura h\u00eddrica mucho mayor que la que proporcionan las inundaciones actuales.<\/span><\/p>

        Cordilleras y elevaci\u00f3n<\/span><\/strong><\/p>

        Algunos sostienen que los f\u00f3siles marinos llegaron a las monta\u00f1as \u00fanicamente a trav\u00e9s del lento levantamiento de antiguos lechos marinos.<\/span><\/p>

        Pero el levantamiento explica la elevaci\u00f3n, no la sedimentaci\u00f3n.<\/span><\/p>

        No lo explica:<\/span><\/p>

        • El volumen de f\u00f3siles<\/span><\/li>
        • Su continuidad lateral<\/span><\/li>
        • Su presencia en todos los continentes<\/span><\/li><\/ul>

          Los f\u00f3siles tuvieron que depositarse antes de que ocurriera el levantamiento del terreno.<\/span><\/p>

          \"\"
          Formaciones rocosas de monta\u00f1a estratificadas que contienen f\u00f3siles marinos, lo que indica que la sedimentaci\u00f3n tuvo lugar antes del levantamiento.<\/span><\/figcaption><\/figure><\/div>

          Un diluvio global encaja con las evidencias.<\/span><\/strong><\/p>

          Una inundaci\u00f3n mundial naturalmente:<\/span><\/p>

          • Cubrir continentes con sedimentos marinos<\/span><\/li>
          • Depositar vida marina en tierra firme<\/span><\/li>
          • Dejan tras de s\u00ed extensas capas f\u00f3siles.<\/span><\/li><\/ul>

            Esto proporciona una explicaci\u00f3n coherente de la distribuci\u00f3n global de los f\u00f3siles marinos.<\/span><\/p>

            Reflexi\u00f3n final<\/span><\/strong><\/p>

            Los f\u00f3siles marinos encontrados en las monta\u00f1as demuestran que los f\u00f3siles no se limitan a los oc\u00e9anos donde vivieron.<\/span><\/p>

            Se encuentran por toda la Tierra.<\/span><\/p>

            La cuesti\u00f3n no es si esto sucedi\u00f3.<\/span><\/p>

            S\u00ed, lo hizo.<\/span><\/p>

            La pregunta es qu\u00e9 tipo de evento fue lo suficientemente grande como para provocarlo.<\/span><\/p>
