Dickinsonia costata modello per esposizione museale e modellismo progettato da DI Silvestro Gianpaolo

Dickinsonia rib model in resin for museum display

Dickinsonia costata belongs to an iconic genus of the Ediacara fauna and was one of the first fossils to indicate the presence of the fauna itself in South Australia. It is a controversial organism and at the moment it is possible to indicate that it is an animal as it has common morphologies with the cnidarians, with the flatworms and with the Placozoa. It is characterized by segments on the body that indicated the age of the animal, as most likely the body lengthening with growth allowed the "addition" of new segments (a bit like the concentric rings of trees) in a way regular but at a decreasing rate with advancing age. It was a small, medium and large species (D. rex) and therefore their size could vary from a few cm to several tens, and they lived in shallow and sandy marine environments. They were organisms that did not live fixed to a surface as they possessed flexible structures, which allowed some movement and the maintenance of an ovoid body shape, suggesting that they do not belong to known groups of animals. The model is supplied in transparent resin or transparent blue.
