| Résumé | (disponible en anglais seulement)
The colonization of land was a major evolutionary transition. Ichnological evidence suggests that this process may have begun at the end of the Ediacaran, with
incursions into very shallow, marginal-marine settings. Animals made their first unequivocal amphibious terrestrial forays during the Cambrian and had managed to establish themselves in truly alluvial environments by the Late Ordovician. The
remainder of the Palaeozoic is characterized by an explosion of diversity and a progressive expansion from coastal settings inland into rivers, floodplains, deserts and lakes; as well as increasing colonization of infaunal ecospace and the creation
of new niches. A framework is presented for analysing ecospace occupation and ecosystem engineering through the use of trace fossil data. The colonization of each new continental environment may be viewed as a series of repeated experiments in
ecospace filling and niche creation. A pattern emerges in which colonization of a new environment is followed by rapid filling of ecospace, after which animals establish new behavioural programmes represented initially by the appearance of original
trace fossil architectural designs, and subsequently by a proliferation of ichnogenera representing variation upon these established themes. This pattern is consistent with the early burst model of diversification. |
| Sommaire | (Résumé en langage clair et simple, non publié)
Preuve de traces fossiles (preuve fossilisée du comportement animal, par exemple, des pistes, des sentiers, des terriers) nous permet de
reconstituer l'histoire de la colonisation précoce de la terre par les animaux. Cette eu lieu à peu près à l'époque il ya entre 540 millions et 440 millions d'années. Il semble que ecospace dans chaque nouvel environnement a été rempli rapidement
après la colonisation initiale, avec la diversification des comportements dans l'environnement suivant plus tard. |
