Biota ediacárica, los primeros ecosistemas macroscópicos complejos de la tierra.

Palabras clave: Ediacárico, Pluricelularidad, Animales, Paleontología, Evolución


La biota ediacárica representa uno de los mayores hitos en la historia evolutiva del planeta, pues contiene a las primeras formas de vida pluricelulares macroscópicas bien conocidas en el registro fósil, además de poseer integrantes microscópicos de gran relevancia evolutiva como los posibles primeros animales triploblásticos y embriones. Su posición estratigráfica corresponde con el final del Neoproterozoico, tiempo de origen de los primeros organismos eucarióticos. La mayoría de los planes corporales de los organismos macroscópicos del Ediacárico no tienen equivalentes modernos e incluyen simetrías triradiales, octoradiales y fractales. La biota ediacárica vio su final al evolucionar los primeros organismos macrodepredadores que luego dominarían los ecosistemas del Fanerozoico.
