<\/h2>\nEl C\u00e1mbrico es el primer per\u00edodo de la Era Paleozoica, este a su vez se subdivide en cuatro \u00e9pocas y diez edades. Comenz\u00f3 hace 538.8 \u00b10.6 millones de a\u00f1os antes del presente y termin\u00f3 hace unos 486.9 \u00b11.5 millones de a\u00f1os. Debe su nombre a la denominaci\u00f3n Cambria, que es la forma latinizada de Cymru, t\u00e9rmino con el que los galeses se refieren a su pa\u00eds, Gales, lugar donde el ge\u00f3logo ingl\u00e9s Adam Sedgwick identific\u00f3 este sistema en 1831. En la literatura cient\u00edfica tambi\u00e9n puede encontrarse como Cambriano, t\u00e9rmino hoy obsoleto. Durante este momento existieron cuatro grandes paleocontinentes: Laurentia, B\u00e1ltica, Siberia y Gondwana, y una serie de terrenos distribuidos en la periferia de estos.<\/p>\n

El esquema de la Comisi\u00f3n Internacional de Estratigraf\u00eda -ICS ha establecido una secci\u00f3n de estratotipo para la base del C\u00e1mbrico, fechada con bastante precisi\u00f3n hace 541 \u00b1 1,0 millones de a\u00f1os. Los cient\u00edficos rusos y chinos han desarrollado un esquema diferente.<\/p>\n
La estratigraf\u00eda se relaciona con el orden de las unidades de roca, sin referirse a sus edades absolutas (que es la cronolog\u00eda). Sin embargo, debido a que los f\u00f3siles, que tradicionalmente son la piedra angular de la estratigraf\u00eda, son relativamente raros en el per\u00edodo C\u00e1mbrico, la cronolog\u00eda tiene un papel importante que desempe\u00f1ar. Si se puede obtener una edad absoluta con un alto grado de precisi\u00f3n para diferentes estratos, tambi\u00e9n se puede establecer su edad relativa.<\/p>\n
La base del per\u00edodo C\u00e1mbrico se define oficialmente como la primera aparici\u00f3n de cierto rastro f\u00f3sil, Treptichnus pedum. Sin embargo, este f\u00f3sil tambi\u00e9n aparece en rocas m\u00e1s antiguas que la localidad que marca oficialmente el inicio del per\u00edodo.[\/et_pb_text][\/et_pb_column][et_pb_column type=\u00bb1_2″ _builder_version=\u00bb4.16″ custom_padding=\u00bb|||\u00bb global_colors_info=\u00bb{}\u00bb custom_padding__hover=\u00bb|||\u00bb][et_pb_image src=\u00bbhttps:\/\/clientes.munecarusa.com\/mp\/wp-content\/uploads\/2025\/01\/Estratigrafia-Periodo-Cambrico.webp\u00bb alt=\u00bbEstratigraf\u00eda de la \u00e9poca C\u00e1mbrica\u00bb show_in_lightbox=\u00bbon\u00bb use_overlay=\u00bbon\u00bb overlay_icon_color=\u00bb#660000″ hover_overlay_color=\u00bbrgba(0,0,0,0.5)\u00bb force_fullwidth=\u00bbon\u00bb overlay_icon_color_last_edited=\u00bboff|desktop\u00bb _builder_version=\u00bb4.27.4″ _module_preset=\u00bbdefault\u00bb custom_margin=\u00bb||0px||false|false\u00bb custom_padding=\u00bb||0px||false|false\u00bb global_colors_info=\u00bb{}\u00bb][\/et_pb_image][et_pb_text content_last_edited=\u00bboff|desktop\u00bb _builder_version=\u00bb4.27.2″ text_text_color=\u00bb#FFFFFF\u00bb header_4_font=\u00bb||||||||\u00bb background_color=\u00bb#660000″ background_size=\u00bbinitial\u00bb background_position=\u00bbtop_left\u00bb background_repeat=\u00bbrepeat\u00bb text_orientation=\u00bbcenter\u00bb custom_padding=\u00bb20px|30px|20px|30px|true|true\u00bb text_font_size_tablet=\u00bb16px\u00bb text_font_size_phone=\u00bb14px\u00bb text_font_size_last_edited=\u00bbon|phone\u00bb text_line_height_tablet=\u00bb1.7em\u00bb text_line_height_phone=\u00bb1.6em\u00bb text_line_height_last_edited=\u00bbon|phone\u00bb header_4_font_size_last_edited=\u00bboff|phone\u00bb global_colors_info=\u00bb{}\u00bb]Secci\u00f3n del l\u00edmite ediacarano-c\u00e1mbrico en Fortune Head, Canada.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row make_equal=\u00bbon\u00bb custom_padding_last_edited=\u00bboff|phone\u00bb _builder_version=\u00bb4.27.0″ background_size=\u00bbinitial\u00bb background_position=\u00bbtop_left\u00bb background_repeat=\u00bbrepeat\u00bb custom_margin=\u00bb||||false|false\u00bb custom_margin_phone=\u00bb||||false|false\u00bb custom_margin_last_edited=\u00bboff|phone\u00bb custom_padding=\u00bb||||false|false\u00bb custom_padding_tablet=\u00bb||||false|false\u00bb animation_style=\u00bbslide\u00bb global_colors_info=\u00bb{}\u00bb][et_pb_column type=\u00bb4_4″ _builder_version=\u00bb4.16″ custom_padding=\u00bb|||\u00bb global_colors_info=\u00bb{}\u00bb custom_padding__hover=\u00bb|||\u00bb][et_pb_text content_last_edited=\u00bboff|desktop\u00bb _builder_version=\u00bb4.27.2″ text_text_color=\u00bb#444444″ header_4_font=\u00bb||||||||\u00bb background_size=\u00bbinitial\u00bb background_position=\u00bbtop_left\u00bb background_repeat=\u00bbrepeat\u00bb text_orientation=\u00bbjustified\u00bb text_font_size_tablet=\u00bb16px\u00bb text_font_size_phone=\u00bb14px\u00bb text_font_size_last_edited=\u00bbon|phone\u00bb text_line_height_tablet=\u00bb1.7em\u00bb text_line_height_phone=\u00bb1.6em\u00bb text_line_height_last_edited=\u00bbon|phone\u00bb ul_line_height_last_edited=\u00bboff|phone\u00bb header_4_font_size_last_edited=\u00bboff|phone\u00bb global_colors_info=\u00bb{}\u00bb]Sin embargo, hay un per\u00edodo de cambio biol\u00f3gico que hace que este per\u00edodo de tiempo sea bueno para demarcar el C\u00e1mbrico de los per\u00edodos del e\u00f3n del Fanerozoico anterior y el supere\u00f3n Prec\u00e1mbrico.

Esto se debe, en parte, a la ausencia de grandes capas de hielo en los polos, lo que indicaba un clima global m\u00e1s estable y c\u00e1lido.<\/p>\n
Adem\u00e1s, el hecho de que una gran parte del hemisferio norte estuviera cubierta por el vasto oc\u00e9ano Panthalassa contribuy\u00f3 a moderar las temperaturas. Este inmenso oc\u00e9ano actuaba como un regulador clim\u00e1tico, distribuyendo el calor de manera relativamente uniforme por el planeta, lo que sugiere que el clima era predominantemente templado y oce\u00e1nico. Las \u00e1reas continentales que exist\u00edan eran peque\u00f1as en comparaci\u00f3n con los oc\u00e9anos, lo que permit\u00eda que las condiciones marinas influyeran de manera significativa en la estabilidad y la suavidad del clima global durante este per\u00edodo.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row make_equal=\u00bbon\u00bb custom_padding_last_edited=\u00bboff|phone\u00bb admin_label=\u00bbFlora\u00bb _builder_version=\u00bb4.27.0″ background_size=\u00bbinitial\u00bb background_position=\u00bbtop_left\u00bb background_repeat=\u00bbrepeat\u00bb custom_margin=\u00bb||0px||false|false\u00bb custom_margin_phone=\u00bb||||false|false\u00bb custom_margin_last_edited=\u00bboff|phone\u00bb custom_padding=\u00bb||0px||false|false\u00bb custom_padding_tablet=\u00bb||||false|false\u00bb animation_style=\u00bbslide\u00bb global_colors_info=\u00bb{}\u00bb][et_pb_column type=\u00bb4_4″ _builder_version=\u00bb4.16″ custom_padding=\u00bb|||\u00bb global_colors_info=\u00bb{}\u00bb custom_padding__hover=\u00bb|||\u00bb][et_pb_text content_last_edited=\u00bboff|desktop\u00bb disabled_on=\u00bboff|off|off\u00bb _builder_version=\u00bb4.27.0″ header_4_font=\u00bb|700||on|||||\u00bb header_4_text_align=\u00bbleft\u00bb header_4_text_color=\u00bb#444444″ header_4_font_size=\u00bb30px\u00bb background_size=\u00bbinitial\u00bb background_position=\u00bbtop_left\u00bb background_repeat=\u00bbrepeat\u00bb animation_style=\u00bbzoom\u00bb text_font_size_last_edited=\u00bboff|phone\u00bb text_line_height_last_edited=\u00bboff|phone\u00bb header_4_font_size_tablet=\u00bb25px\u00bb header_4_font_size_phone=\u00bb20px\u00bb header_4_font_size_last_edited=\u00bbon|tablet\u00bb global_colors_info=\u00bb{}\u00bb text_line_height__hover_enabled=\u00bboff|hover\u00bb]<\/p>\n

La extinci\u00f3n de los arqueociatos a fines del C\u00e1mbrico Inferior provoc\u00f3 que a partir de este momento las comunidades arrecifales estuvieron dominadas casi exclusivamente por construcciones de origen microbiano. Las demoesponjas espiculadas r\u00edgidas comenzaron a formar arrecifes reci\u00e9n en el C\u00e1mbrico Superior, sin embargo, estos nuevos arrecifes no alcanzaron niveles de complejidad similares a los de sus contrapartes del C\u00e1mbrico Inferior reci\u00e9n hasta el Ordov\u00edcico Medio.<\/p>\n
Cambios en la bioturbaci\u00f3n de los sedimentos se asocian a la adquisici\u00f3n de nuevas estrategias de alimentaci\u00f3n, as\u00ed como el aumento de la capacidad de excavar y remover los sedimentos. Esto llev\u00f3 a una reducci\u00f3n dr\u00e1stica de tapetes microbianos, incapaces de competir con los metazoos.<\/p>\n
Sin embargo, resulta dif\u00edcil determinar si los cambios fueron dr\u00e1sticos o graduales; si bien la falta de registro podr\u00eda se\u00f1alar un cambio dr\u00e1stico, el C\u00e1mbrico inferior de la Zona Centroib\u00e9rica (que antiguamente se consideraba azoico) muestra signos m\u00e1s graduales.[\/et_pb_text][\/et_pb_column][et_pb_column type=\u00bb1_2″ _builder_version=\u00bb4.16″ custom_padding=\u00bb|||\u00bb global_colors_info=\u00bb{}\u00bb custom_padding__hover=\u00bb|||\u00bb][et_pb_image src=\u00bbhttps:\/\/clientes.munecarusa.com\/mp\/wp-content\/uploads\/2025\/01\/Fauna-Periodo-Cambrico-01.webp\u00bb alt=\u00bbPer\u00edodo C\u00e1mbrico\u00bb show_in_lightbox=\u00bbon\u00bb use_overlay=\u00bbon\u00bb overlay_icon_color=\u00bb#660000″ hover_overlay_color=\u00bbrgba(0,0,0,0.5)\u00bb force_fullwidth=\u00bbon\u00bb overlay_icon_color_last_edited=\u00bboff|desktop\u00bb _builder_version=\u00bb4.27.4″ _module_preset=\u00bbdefault\u00bb custom_margin=\u00bb||0px||false|false\u00bb custom_padding=\u00bb||0px||false|false\u00bb global_colors_info=\u00bb{}\u00bb][\/et_pb_image][et_pb_text content_last_edited=\u00bboff|desktop\u00bb _builder_version=\u00bb4.27.2″ text_text_color=\u00bb#FFFFFF\u00bb header_4_font=\u00bb||||||||\u00bb background_color=\u00bb#660000″ background_size=\u00bbinitial\u00bb background_position=\u00bbtop_left\u00bb background_repeat=\u00bbrepeat\u00bb text_orientation=\u00bbcenter\u00bb custom_padding=\u00bb20px|30px|20px|30px|true|true\u00bb text_font_size_tablet=\u00bb16px\u00bb text_font_size_phone=\u00bb14px\u00bb text_font_size_last_edited=\u00bbon|phone\u00bb text_line_height_tablet=\u00bb1.7em\u00bb text_line_height_phone=\u00bb1.6em\u00bb text_line_height_last_edited=\u00bbon|phone\u00bb header_4_font_size_last_edited=\u00bboff|phone\u00bb global_colors_info=\u00bb{}\u00bb]F\u00f3sil de conchas marinas del per\u00edodo C\u00e1mbrico.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row make_equal=\u00bbon\u00bb _builder_version=\u00bb4.27.0″ background_size=\u00bbinitial\u00bb background_position=\u00bbtop_left\u00bb background_repeat=\u00bbrepeat\u00bb custom_margin=\u00bb||||false|false\u00bb custom_padding=\u00bb||||false|false\u00bb animation_style=\u00bbslide\u00bb global_colors_info=\u00bb{}\u00bb][et_pb_column type=\u00bb4_4″ _builder_version=\u00bb4.16″ custom_padding=\u00bb|||\u00bb global_colors_info=\u00bb{}\u00bb custom_padding__hover=\u00bb|||\u00bb][et_pb_text content_last_edited=\u00bboff|desktop\u00bb _builder_version=\u00bb4.27.2″ text_text_color=\u00bb#444444″ header_4_font=\u00bb||||||||\u00bb background_size=\u00bbinitial\u00bb background_position=\u00bbtop_left\u00bb background_repeat=\u00bbrepeat\u00bb text_orientation=\u00bbjustified\u00bb text_font_size_tablet=\u00bb16px\u00bb text_font_size_phone=\u00bb14px\u00bb text_font_size_last_edited=\u00bbon|phone\u00bb text_line_height_tablet=\u00bb1.7em\u00bb text_line_height_phone=\u00bb1.6em\u00bb text_line_height_last_edited=\u00bbon|phone\u00bb header_4_font_size_last_edited=\u00bboff|phone\u00bb global_colors_info=\u00bb{}\u00bb]En los niveles m\u00e1s inferiores del per\u00edodo C\u00e1mbrico (Nemakit-Daldyniense-Tommotiense, 543-530 millones de a\u00f1os), aparecen numerosos elementos esquel\u00e9ticos de peque\u00f1o tama\u00f1o, denominados small shelly fossils (\u00abf\u00f3siles de conchas peque\u00f1os\u00bb), que morfol\u00f3gicamente se han relacionado con lofotrocozoos pero que no pertenecen a este grupo de manera espec\u00edfica; muchos de ellos se parecen a moluscos, otros a braqui\u00f3podos, algunos a cnidarios, etc. Es un grupo bastante diverso, pero sin duda, hay organismos bilaterales entre ellos. Encontramos adem\u00e1s gran parte de los filos de animales actuales (esp\u00edculas de esponjas, restos de primitivos moluscos, as\u00ed como los primeros representantes de los trilobites). Este grupo radi\u00f3 hasta convertirse en los organismos por excelencia del Paleozoico. Tambi\u00e9n datan de este \u00e9poca distintos taxones de equinodermos extintos: Edrioasteroidea, Helicoplacoidea, Eocrinoidea, Homalozoa, Homostelea, Ctenocystoidea, Homoiostelea, Stylophora.<\/p>\n
Una revoluci\u00f3n del per\u00edodo C\u00e1mbrico fue sin duda la aparici\u00f3n de esqueletos, quiz\u00e1s motivada por los cambios en la qu\u00edmica de los oc\u00e9anos (los continentes estaban en posici\u00f3n ecuatorial, con climas muy c\u00e1lidos y f\u00e1cil precipitaci\u00f3n de carbonatos, por lo que el gasto metab\u00f3lico era menor). Tambi\u00e9n la aparici\u00f3n de nuevos predadores fue importante, pues se necesitaban estructuras que facilitaran la locomoci\u00f3n y protegieran los tejidos blandos. As\u00ed pues aparecieron los primeros exoesqueletos (elementos m\u00faltiples) similares a los aplac\u00f3foros (entre 18 y 6000 metros de profundidad y cubiertos con esp\u00edculas calc\u00e1reas) y poliplac\u00f3foros (placas imbricadas).

Entre los grupos m\u00e1s afectados se encontraban los arqueociatos, un tipo de organismo marino que desempe\u00f1aba un papel importante en la construcci\u00f3n de los primeros arrecifes de la historia de la Tierra. Estos seres, que viv\u00edan en aguas poco profundas y c\u00e1lidas, desaparecieron casi por completo en este evento, lo que result\u00f3 en el colapso de los ecosistemas que depend\u00edan de sus estructuras arrecifales.<\/p>\n

Aunque no se extinguieron por completo en esta fase, muchas de sus especies sufrieron una importante reducci\u00f3n.
