Abstract

LECH, Roberto Ricardo. Inner morphology of Palaeoanemone (Cnidaria: Actiniaria): a burrowing anemone of the Carboniferous of Argentina. Ser. correl. geol. [online]. 2009, vol.25, n.1, pp.27-36. ISSN 1666-9479.

The rocks of marine carboniferous of Argentina present numerous associations of invertebrates, among which can be found burrowing anemones and also traces of its biological activity. Palaeoanemone is an exceptional case of fossilization of these organisms, preserving its morphology both external and internal. The anatomical knowledge that is known about the morphology of this genus is enlarged by observing details of the walls of their body, peristome and pharynx, as well as mesenteries and tentacles.

Keywords : Cnidaria; Actiniaria; Inner Morphology; Carboniferous; Argentina.
