Desde entonces, los paleont??logos han especulado con un sinf??n de teor??as sobre su origen y evoluci??n. Hoy sabemos que los ictiosaurios&nbsp;<strong>proced??an de reptiles terrestres y evolucionaron r??pidamente<\/strong>, adapt??ndose al ambiente marino tal y como ocurri?? con las ballenas millones de a??os despu??s.<\/p>\n\n\n\n<p>???Gran Breta??a es el lugar de nacimiento de los ictiosaurios: sus f??siles se han desenterrado aqu?? durante m??s de 200 a??os, y la primera cient??fica se remonta a Mary Anning y sus descubrimientos a lo largo de la Costa Jur??sica. A pesar de los muchos f??siles de ictiosaurios encontrados, es notable que el ictiosaurio de Rutland es el esqueleto m??s grande jam??s encontrado en el Reino Unido.
