• W2516588455 abstract "espanolMuchas especies de pteridospermas que se encuentran preservadas de forma abundante en rocas triasicas de Gondwana, poseen patrones de variacion morfologica notables que han sido atribuidos a modelos de especiacion relacionados con la hibridacion. Sin embargo, este es un razonamiento improbable, porque la hibridacion es un fenomeno que se produce raramente en las gimnospermas. Es mas facil explicar esta diversidad morfologica, que esta bien representada en las floras del intervalo Anisiense-Noriense (Triasico Medio y Superior) de Australasia y otras regiones de Gondwana, por un proceso de especiacion alopatrica debido a un conjunto de factores relacionados con provincialismos geograficos y climaticos. La mayor parte de los especimenes estudiados en este trabajo pertenecen a tres familias: Umkomasiaceae, Peltaspermaceae y Matatiellaceae. Estas, junto con varios generos posiblemente pteridospermicos, se revisan en este estudio. La diversidad especifica en las familias mencionadas aparentemente declino a partir del Retiense, y no se restablecio en el post-Triasico de Gondwana. Los estratos post-Triasicos de Australasia contienen distintas asociaciones floristicas notablemente distintas. Ninguna de las fructificaciones encontradas hasta el momento son claramente pteridospermicas. Ademas, ningun otro tipo de resto hallado presenta alguna relacion obvia con las pteridospermas del Triasico de Gondwana. Las fructificaciones de Caytoniales no se conocen en las rocas de Australasia; sin embargo, se han registrado filocenosis relacionables con plantas de este orden en el Este de Gondwana, incluida Australia, desde el Triasico Superior hasta el Jurasico Medio. A partir del Jurasico Inferior hasta el Eoceno, una gran parte de los restos foliares con aspecto de helecho que se han relacionado en Gondwana con las pteridospermas no presentan evidencias reales para atribuirlos a este grupo de gimnospermas espanolPteridosperms are preserved abundantly in the Gondwanan Triassic, with many species exhibiting considerable morphological variation that has been attributed to a hybridization model of speciation. This is an improbable explanation given that hybridization is very rare in gymnosperms. Allopatric speciation resulting from geographic and climatic provincialism is a more likely explanation for the morphological diversity which is well represented in Anisian–Norian (Middle and Upper Triassic) floras of Australasia and elsewhere in Gondwana. Most specimens are distributed among three families: Umkomasiaceae, Peltaspermaceae and Matatiellaceae. These families, together with other possibly pteridospermous genera, are reviewed herein. Diversity in these families apparently declined by the Rhaetian and they did not persist into the Gondwanan post-Triassic. Australasian post-Triassic strata contain remarkably different floral assemblages to those of the Triassic. No fructifications are clearly pteridospermous and no remains show any obvious relationship with pteridosperms of the Gondwanan Triassic. Caytonialean fructifications are not known in Australasian strata; however, associated foliage has been reported from the Eastern Gondwanan Upper Triassic through Middle Jurassic including Australia. Much fern-like foliage, claimed to be pteridospermous from the Lower Jurassic through Eocene of Eastern Gondwana, lacks supporting evidence of such affiliation" @default.
