Un equipo cient\u00edfico ha descubierto un nuevo y \u00abextraordinario\u00bb depredador del tama\u00f1o de un dedo \u00edndice, con tres ojos y 506 millones de a\u00f1os de antig\u00fcedad, procedente del yacimiento canadiense de Burgess Shale.<\/p>\n

Con garras articulares y espinosas, una boca circular llena de dientes y un cuerpo con aletas a los lados para nadar, los paleont\u00f3logos del Museo Manitoba y del Museo Real de Ontario, ambos en Canad\u00e1, han denominado a este nuevo ejemplar Mosura fentoni.<\/p>\n

Sus rasgos demuestran que formaba parte de un grupo extinto conocido como radiodontas, que tambi\u00e9n inclu\u00eda \u00abal famoso\u00bb Anomalocaris canadensis, un depredador de un metro de largo que compart\u00eda las aguas con Mosura, explica un comunicado del museo de Ontario.<\/p>\n

Con garras articulares y espinosas, una boca circular llena de dientes y un cuerpo con aletas a los lados para nadar. Paleont\u00f3logos de Canad\u00e1 lo han denominado ‘Mosura fentoni’<\/p>\n

No obstante, este \u00faltimo pose\u00eda una caracter\u00edstica que no se hab\u00eda visto en ning\u00fan otro radiodonta: una regi\u00f3n del cuerpo parecida al abdomen y formada por m\u00faltiples segmentos en su extremo posterior.<\/p>\n

Mosura tiene 16 segmentos compactos revestidos de branquias en el extremo posterior de su cuerpo, explica Joe Moysiuk, del Museo de Manitoba.<\/p>\n

Se trata, dice, de \u00abun claro ejemplo\u00bb de convergencia evolutiva con grupos modernos, como los cangrejos herradura, las cochinillas y los insectos, que comparten una serie de segmentos con \u00f3rganos respiratorios en la parte posterior del cuerpo.<\/p>\n

<\/a><\/p>\n

Intrigante adaptaci\u00f3n<\/h2>\n

La raz\u00f3n de esta \u00abintrigante adaptaci\u00f3n\u00bb sigue siendo incierta, pero los investigadores postulan que puede estar relacionada con una preferencia particular de h\u00e1bitat o con caracter\u00edsticas de comportamiento de Mosura que requer\u00edan una respiraci\u00f3n m\u00e1s eficiente.<\/p>\n

Los radiodontas fueron el primer grupo de artr\u00f3podos que se ramific\u00f3 en el \u00e1rbol evolutivo. Proporcionan una visi\u00f3n clave de los rasgos ancestrales de todo el grupo<\/p>\n

\u00abLos radiodontas fueron el primer grupo de artr\u00f3podos que se ramific\u00f3 en el \u00e1rbol evolutivo, por lo que proporcionan una visi\u00f3n clave de los rasgos ancestrales de todo el grupo. La nueva especie pone de relieve que estos primeros artr\u00f3podos ya eran sorprendentemente diversos y se adaptaban de forma comparable a sus lejanos parientes modernos\u00bb, afirma Jean-Bernard Caron, del museo de Ontario.<\/p>\n

Los detalles del nuevo depredador se publican en la revista Royal Society Open Science. Los f\u00f3siles muestran adem\u00e1s detalles de anatom\u00eda interna, incluidos elementos del sistema nervioso, circulatorio y digestivo.<\/p>\n

Los yacimientos de Burgess Shale, designados Patrimonio de la Humanidad por la Unesco en 1980, se encuentran en los Parques Nacionales de Yoho y Kootenay.<\/p>","protected":false},"excerpt":{"rendered":"
