Científicos identifican al depredador marino gigante Tylosaurus rex a partir de fósiles en Texas

Se ha descrito una nueva especie de reptil marino masivo, el Tylosaurus rex, a partir de fósiles desenterrados en el norte de Texas. Este mosasaurio de 13 metros de largo vivió hace aproximadamente 80 millones de años y se sitúa entre los más grandes de su especie. Los investigadores publicaron los hallazgos el 21 de mayo de 2026.

El descubrimiento fue dirigido por científicos del Museo Americano de Historia Natural, el Museo de Naturaleza y Ciencia Perot en Dallas y la Universidad Metodista del Sur. La autora principal, Amelia Zietlow, señaló que los fósiles habían sido identificados erróneamente en un principio como otra especie antes de que comparaciones detalladas revelaran rasgos distintivos, incluyendo un mayor tamaño y dientes finamente serrados. El espécimen holotipo, hallado en 1979 cerca de un embalse en las afueras de Dallas, se encuentra ahora en exhibición en el Museo Perot.

Researchers have uncovered evidence that octopuses from the Late Cretaceous period, around 100 million years ago, grew to lengths of nearly 20 meters and hunted as top predators. The findings, based on well-preserved fossil jaws from Japan and Vancouver Island, challenge previous views of early octopus evolution. Professor Yasuhiro Iba of Hokkaido University led the study, published in Science on April 23.
