\nBalena numit\u0103 Perucetus colossus sau \u201ebalena colosal\u0103 peruan\u0103” a tr\u0103it \u00een urm\u0103 cu 38-40 de milioane de ani, \u00een epoca Eocenului. Perucetus este uria\u015f\u0103 \u015fi ar fi putut dep\u0103\u015fi masa balenei albastre, considerat\u0103 mult timp cel mai greu animal \u00eenregistrat vreodat\u0103.<\/p>\n
\nCercet\u0103torii au estimat c\u0103 Perucetus avea o lungime de aproximativ 20 de metri \u015fi o greutate de p\u00e2n\u0103 la 340 de tone. Dac\u0103 se confirm\u0103, mas\u0103 ar dep\u0103\u015fi orice alt animal cunoscut, inclusiv balena albastr\u0103 de ast\u0103zi \u015fi cei mai mari dinozauri.<\/p>\n
\n\u201eCaracteristica principal\u0103 a acestui animal este cu siguran\u0163\u0103 greutatea extrem\u0103, ceea ce sugereaz\u0103 c\u0103 evolu\u0163ia poate genera organisme care au caracteristici care dep\u0103\u015fesc imagina\u0163ia noastr\u0103”, a declarat paleontologul Giovanni Bianucci de la Universitatea din Pisa, Italia, autorul principal al cercet\u0103rii publicate \u00een revista Nature.<\/p>\n
\nScheletul par\u0163ial al lui Perucetus a fost excavat \u00eentr-un de\u015fert din sudul Peru. Nu au fost g\u0103site resturi craniene sau dentare, ceea ce face ca interpretarea dietei \u015fi a stilului de via\u0163\u0103 s\u0103 fie mai dificil\u0103. Cercet\u0103torii cred c\u0103 Perucetus nu era un pr\u0103d\u0103tor activ, ci un animal care se hr\u0103nea la fundul apelor de coast\u0103 pu\u0163in ad\u00e2nci.<\/p>\n
\n\u201eDin cauza scheletului s\u0103u greu \u015fi, cel mai probabil, a corpului s\u0103u foarte voluminos, acest animal era cu siguran\u0163\u0103 un \u00eenot\u0103tor lent. Mi se pare, \u00een acest stadiu al cercet\u0103rilor noastre, c\u0103 este un fel de gigant pa\u015fnic, un pic ca un lamantin supradimensionat. Trebuie s\u0103 fi fost un animal foarte impresionant, dar poate nu at\u00e2t de \u00eenfrico\u015f\u0103tor”, a declarat paleontologul Olivier Lambert de la Institutul Regal Belgian de \u015etiin\u0163e Naturale din Bruxelles.<\/p>\n
\nBalenele au evoluat \u00een urm\u0103 cu peste 50 de milioane de ani, pornind de la mamifere care tr\u0103iau pe uscat.<\/p>\n","protected":false},"excerpt":{"rendered":"
