Product information "Calamites"

Stem of a giant horsetail fern. Very well preserved on both sides.

Age: Upper Carboniferous
Locality: Piesberg, Osnabrück, Germany
Size: 11.5 x 12 cm

Plants like these and Lepidodendron formed the first forests on earth, which had a huge impact on life on dry land. Forests form rich soils, provide a habitat for animals from root to crown, provide a large amount of biomass and can even create their own microclimate. Because initially only very few animals could digest cellulose and lignine, many plants were buried and fossilized as coal. This removed so much carbon dioxide from the atmosphere that towards the end of the carboniferous temperatures dropped and ice caps formed at the poles.

The colors on pictures can differ from the originals for technical reasons.

Araucarien-Holz (anpoliert)
Age: TriassicLocality: MadagascarSize: 2-3 cmAraucaria are conifers that carry pointy, blade-like, hard leaves. They are nowdays only found in South America and Oceania, which is a relic from the time they were spread over the entire ancients southern continent of Gondwana (the remnants of which are now, South America, Africa, India, Antarctica and Australia).The wood petrified by way of silica permineralisation, also know as silicification. When the wood is deposited in an anoxic environment, it usually coalifies. But if at the same time it is inundated with mineral waters (very often volcanically sourced, the precipitated silica fills out the the cavities in the wood and then tparts that get slowly decomposed by anaerobic bacteria.The picture is a sample. You will get a similar specimen.
