Un equipo de investigadores halló en Brasil un fósil de 113 millones de años de una serpiente de cuatro patas. Aunque no es la primera vez que se encuentra un fósil de serpiente con extremidades, se cree que éste es el ancestro directo de las serpientes modernas.

Creen que el animal no utilizaba sus delicados brazos y patas para caminar sino que le servían para atrapar a su presa. El fósil muestra adaptaciones para excavar, y no para nadar, lo cual refuerza la idea de que las culebras evolucionaron en tierra.

Si evolucionaron en tierra o en el agua es un debate de larga data entre paleontólogos.

“Éste es el fósil de serpiente más primitivo que se conoce, y es muy claro que no es acuática”, señaló Nick Longrich, investigador de la Universidad de Bath, en Reino Unido, y uno de los autores del estudio.
