Description:
Pecoits et al. (Reports, 29 June 2012, p. 1693) describe bilaterian trace fossils and assign them an Ediacaran age based on the age of a granite interpreted as intrusive. We argue that the granite is not intrusive but in fact represents the basement of the sedimentary succession. Moreover, we show that identical trace fossils occur in nearby Carboniferous-Permian glacigenic rocks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gaucher, Claudio -- Poire, Daniel G -- Bossi, Jorge -- Bettucci, Leda Sanchez -- Beri, Angeles -- New York, N.Y. -- Science. 2013 Feb 22;339(6122):906. doi: 10.1126/science.1230339.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departamento de Geologia, Facultad de Ciencias, Universidad de la Republica Igua 4225, 11400 Montevideo, Uruguay. gaucher@chasque.net〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23430638" target="_blank"〉PubMed〈/a〉
