These organisms lived during the Triassic period and are important microfossils in limestone deposits from this epoch.The thallus (plant body) shows euspondylar branching, the lateral branches are arranged in regular whirls, which is clearly visible on this specimen. Chaetocladus is of paleontological importance, as these algae can provide us with information about the environmental conditions and the development of marine ecosystems during the Triassic.Age: Devonian, Givet-Frasne boundary, Upper Plattenkalk;Locality: Heiligenstock, Bergisch Gladbach-Sand, North Rhine-Westphalia, GermanySize: approx. 14 x 12 cmColors on product photos may differ slightly from those of the original specimen due to technical reasons.
