DESCRIPCI\u00d3<\/h6>\n
El g\u00e8nere Nautilus \u00e9s un t\u00e0xon que cont\u00e9 set esp\u00e8cies de n\u00e0utils. D’aquestes en queden quatre de vivents, que difereixen significativament en aspectes de morfologia dels n\u00e0utils empla\u00e7ats en el t\u00e0xon germ\u00e0 Allonautilus
\n\u00c9s el f\u00f2ssil, d\u2019un n\u00e0util, un grup de cefal\u00f2podes molt antics, van ser els primers que van existir.<\/p>\n
Aquest f\u00f2ssil va ser descobert per Carl Linnaeus, un bot\u00e0nic i cient\u00edfic su\u00e8c. Al 1758, per\u00f2 el f\u00f2ssil ja podia existir des de fa 500 milions d\u2019anys.<\/p>\n
Carl Linnaeus, va n\u00e9ixer R\u00e5shult, Sm\u00e5land, Su\u00e8cia, 23 de maig del 1707 i va morir a Uppsala, Su\u00e8cia, 10 de gener de 1778), fou un bot\u00e0nic, cient\u00edfic, metge, i zo\u00f2leg suec que establ\u00ed els fonaments del sistema modern de la nomenclatura binomial. \u00c9s considerat el pare de la taxonomia moderna i conegut com un dels pares de l’ecologia moderna.<\/p>\n
\u00c8POCA GEOL\u00d2GICA<\/h6>\n
De cada f\u00f2ssil cal descriure l\u2019\u00e8poca geol\u00f2gica on va viure, incloent-hi imatges (m\u00ednim 250 carac.)<\/p>\n
Al ser un dels primers cefal\u00f2podes que van existir, el f\u00f2ssil podria tenir fins i tot 500 milions d\u2019anys<\/p>\n
\u00daS<\/h6>\n
La closca del Nautilus, tallada pel seu pla aproximat de simetria, dona lloc a dues mitats que constitueixen un exemple cl\u00e0ssic d\u2019espiral aproximadament longar\u00ectmica
\ntamb\u00e9 es pot dir espiral equiangular.<\/p>\n
LLOC D\u2019ORIGEN<\/h6>\n
Aquest f\u00f2ssil, prov\u00e9 del Marroc, un pa\u00eds situat al nord d\u2019\u00c0frica. La seva poblaci\u00f3 \u00e9s de 32.309.000 h i la seva extensi\u00f3 \u00e9s de 442.300 km2. La seva llengua oficial \u00e9s l\u2019\u00e0rab est\u00e0ndard.
\nEl relleu del Marroc \u00e9s principalment muntany\u00f3s, car les muntanyes algerianes de l\u2019Atles hi continuen amb diferents cadenes paral\u00b7leles (el Rif i el sistema de l\u2019Atles). Al N, de cara a la Mediterr\u00e0nia, despr\u00e9s d\u2019una estreta plana costanera, hi ha la cadena jur\u00e0ssica del Rif, que, en forma d\u2019arc, s\u2019est\u00e9n des de l\u2019estret de Gibraltar fins a la vall del riu Moulouya; no ultrapassa els 2.500 m (djebel Tidirhine, 2.456 m).
\nEl clima varia molt dep\u00e9n de la zona: al nord el clima \u00e9s bantant sec, per\u00f2 per la part interior plou m\u00e9s i no ho \u00e9s tant.<\/p>\n
MAPA<\/h6>\nPROCED\u00c8NCIA<\/h6>\n
Aques f\u00f2ssil ens l\u2019ha portat el pare d\u2019un nen d\u2019aquest institiut que \u00e9s ge\u00f2leg, per tant estava molt interessat en el projecte que estavem fent, per aix\u00f2 va portar una capsa plena de f\u00f2ssils, roques i alguns minerals.<\/p>\n
