Científicos describen el primer anfibio marino del Triásico

Investigadores encabezados por Ryosuke Motani de la Universidad de California en Davis describieron al anfibio del Triásico tardío Gerrothorax maritimus, una especie acorazada de aproximadamente un metro que vivió en condiciones totalmente marinas en la zona que hoy corresponde a la provincia de Guizhou, China, y publicaron los hallazgos en Nature Ecology & Evolution. El hallazgo amplía la comprensión de la evolución de los anfibios, desafiando la visión tradicional de que nunca colonizaron el mar, según se señaló en informes anteriores.
