Lo que vale para nosotros es el método: cruzar muchos datos con computadoras permite revisar ideas que parecían cerradas. Para quien lee sobre ciencia, es una buena señal de que las conclusiones de hoy pueden corregirse mañana. Las reconstrucciones se basan en fósiles incompletos, así que el resultado sigue siendo una hipótesis sólida pero no definitiva.","quienFirma":"Universidad de Yale","confianza":"revisado","consulta":{"pregunta":"¿Qué te sorprende más del espinosaurio?"}},"sello":{"hash":"8abaab5581de66da5bb4ef5a2a815690e16e8ee4dc63b5d46d0b16af59212332","sello":"8747e5bbe938a85fe221c35c24b256d20e31fc3d7795bdf9c0ffcf3c608df500","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6583362,"aleatorio":"9d20ff7d43c8e3fe5e9508c31365e99bf7c6ed51dcd7601d9e105871c644dc16","tiempo":"2026-10-25T12:38:00.000Z"},"nist":{"cadena":2,"pulso":1998874,"salida":"6E2DD3FF27CDB528959E4008BB8061B458D149C4A4DB74FCB38F4716BC4B5D5BB755F51E5669DEC372601B493BF762D1547A6CC1F014FB1ED5988F3248B6D729","tiempo":"2026-10-25T12:37:00.000Z"},"noAntes":"2026-10-25T12:38:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 25 12:38:11 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"New evidence suggests spinosaurus spent most of its life underwater","descripcion":"Millions of years after animals first conquered land, some took an extraordinary evolutionary U-turn and returned to the water. Using machine learning and thousands of fossil measurements, Yale scientists have uncovered surprising clues about which prehistoric creatures truly became aquatic. Their findings suggest that Spinosaurus spent most of its life underwater, while some ancient marine reptiles previously thought to be fully aquatic actually spent considerable time on land.","pubDate":"Sun, 25 Oct 2026 07:52:54 EDT","url":"https://www.sciencedaily.com/releases/2026/10/261024221956.htm"},"indexado":"2026-10-25T12:37:35.110Z"}}
