   Jul 17, 2019 · Instead of forests dominated by pines or maple trees, imagine lush forests of large horsetails as tall as 12 metres growing in ecosystems similar to wetlands. In this hot and humid environment, Calamites, the early cousin of modern horsetails, thrived and shaped the Carboniferous world.

   Did Calamites produce xylem?

   • While some horsetails remained herbaceous, like Sphenophyllum, others such as Calamites formed 30 to 50-metre (100-160 ft) high trees like the arborescent lycophytes, and contributed to the understory of the coal swamps of the Carboniferous Period. Calamites produced secondary xylem inside the cambium. What Happened to the Calamites?

   Why are Calamites a fossil?

   • The stems of modern horsetails are typically hollow or contain numerous elongated air-filled sacs. Calamites was similar in that its trunk and stems were hollow, like wooden tubes. When these trunks buckled and broke, they could fill with sediment. This is the reason pith casts of the inside of Calamites stems are so common as fossils.
