Otro detalle que nos ayuda a diferenciar a los dinosaurios de otros grupos es su temporalidad ya que los dinosaurios evolucionaron ya muy entrados en el periodo Tri\u00e1sico, durante la era mesozoica, hace unos 245 millones de a\u00f1os \u00a1Al igual que los primeros mam\u00edferos!<\/span><\/p>\n

Pero en tiempos anteriores tambi\u00e9n existieron enormes animales que dominaron la tierra firme a todo lo largo del supercontinente de Pangea.\u00a0<\/span><\/p>\n

Los primeros tetr\u00e1podos aparecen durante el periodo Dev\u00f3nico del Paleozoico, hace unos 380 millones de a\u00f1os, descendiendo de peces pulmonados capaces de desarrollar parte de su vida fuera del agua: los organismos que coloquialmente llamamos \u201canfibios\u201d.<\/span><\/p>\n

Los anfibios actuales como ranas, sapos, salamandras, tritones, y cecilias solo representan solo una peque\u00f1a rama de la gran diversidad de animales anfibios que vivieron durante el Paleozoico incluyendo al grupo que ser\u00eda ancestro com\u00fan de los reptiles, las aves y los mam\u00edferos; los Amniota.<\/span><\/p>\n

Un linaje muy importante de estos \u201canfibios dominantes\u201d es el de los temnosp\u00f3ndilos que surgi\u00f3 durante el Carbon\u00edfero y prosper\u00f3 dominando los ambientes terrestres y de agua dulce por todo el resto del Paleozoico y bien entrado el Tri\u00e1sico, algunos pocos sobreviviendo hasta el Cret\u00e1cico.\u00a0<\/span><\/p>\n

El grupo incluye organismos depredadores de diversas tallas desde los 30 cent\u00edmetros hasta los 9 metros de largo con g\u00e9neros tan representativos como: <\/span>Cacops<\/span><\/i>,<\/span> Eryops<\/span><\/i>,<\/span> Mastodontosaurus<\/span><\/i>,<\/span> Prionosuchus y Koolasuchus<\/span><\/i>.<\/span><\/p>\n

\u00a0A pesar de su apariencia \u201ccocodriliana\u201d, estos animales NO est\u00e1n cercanamente relacionados ni con los cocodrilos ni con los dinosaurios.<\/span><\/p>\n

No hay un consenso cient\u00edfico sobre la relaci\u00f3n de este grupo de anfibios prehist\u00f3ricos con los Lissamphibia (los anfibios actuales). Mientras que algunos investigadores lo consideran con un linaje paralelo de los anfibios existentes y que se extingui\u00f3 por completo a principios del Cret\u00e1cico, otros sugieren que los Temnospondyli pudieron dar origen a los Lissamphibia, o al menos, a una parte de ellos.<\/span><\/p>\n
