Fósil de 300 millones de años identificado como ancestro del nautilo

Ciencia

Investigadores de la Universidad de Reading y del Museo de Historia Natural de Chicago reanalizaron el fósil Pohlsepia mazonensis, que se consideraba el pulpo más antiguo conocido. El fósil, hallado en Illinois, fue estudiado con técnicas avanzadas de imagen que revelaron detalles anatómicos nuevos que cuestionaron su clasificación previa. Investigaciones posteriores confirmaron que Pohlsepia mazonensis está más relacionado con los nautilus modernos que con los pulpos.

Esta reclasificación cambia la comprensión de la evolución de los cefalópodos y destaca la importancia de la tecnología moderna en los estudios paleontológicos. Los hallazgos fueron reportados por varios medios, subrayando la relevancia del fósil en la historia evolutiva de la vida marina.
