Hallan fósil de una serpiente pitón de 47 millones de años

diciembre 17, 2020

Un grupo de científicos ha hecho un extraordinario hallazgo en el yacimiento de Messel, en Alemania. Consistente en el fósil de una serpiente pitón que se estima tiene 47 millones de años.

El hallazgo sugiere que estos animales habitaron en los tiempos de los neandertales y su origen podría ser europeo.

El grupo internacional de científicos ha bautizado a esta nueva especie de serpiente como Messelopython freyi, mientras que su estudio fue publicado en la revista Biology Letters.

“El origen geográfico de las pitones aún no está claro. Así que el descubrimiento de una nueva especie de pitón en el foso de Messel es, por lo tanto, un gran salto adelante en la comprensión de la historia evolutiva de estas serpientes”, explica en un comunicado, Krister Smith del Instituto de Investigación Senckenberg y el Museo de Historia Natural de Frankfurt.

La serpiente, con una longitud cercana a un metro, se encontraba en perfecto estado, casi completamente conservada.

El lugar donde fue hallado el fósil se trata de un yacimiento Patrimonio Mundial de la UNESCO y, de acuerdo con sus descubridores, este sería el registro más antiguo conocido de una pitón en el mundo.

“Según nuestros hallazgos, estas serpientes ya existían en Europa en la época del Eoceno, hace más de 47 millones de años. ¡Nuestros análisis rastrean su historia evolutiva hasta Europa!”, agrega el doctor Hussam Zaher.

Los mismos investigadores manejan una teoría de lo que le pudo haber pasado a ésta y a otros ejemplares de serpiente pitón en los tiempos antiguos.

“Cuando el clima global comenzó a enfriarse de nuevo después del Mioceno, las pitones desaparecieron una vez más de Europa”, explica Smith.
