Vendotaenid, Kartoniert / Broschiert

Klappentext

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Vendotaenids are ribbon-shaped, carbonaceous, precambrian macrofossils. They are thought to represent giant sulfide-reducing bacteria, similar to Thiomargarita. Many form genera, including Vendotaenida, have been described. The fossils reach around 15 cm in length and are around a millimetre in width. Originally interpreted as brown algae, the fossils are now thought to represent sulfide-reducing bacteria. The carbonaceous fossils, which can be extracted by HF dissolution, are found in precambrian to Early Cambrian rocks, dating from approx. 650 to 530 million years ago.
