Calamites facts for kids
Calamites were ancient, tree-like plants that lived a very long time ago, between 250 and 360 million years ago. They looked a bit like giant horsetails or bamboo. These amazing plants are now extinct, meaning they no longer exist on Earth.

What were Calamites?
Calamites were medium-sized trees. They could grow very tall, reaching heights of 30 to 50 meters (about 100 to 160 feet). Imagine a tree as tall as a 10-story building! Their trunks looked a lot like bamboo, with clear segments and joints.
Leaves and Reproduction
The leaves of Calamites were needle-shaped. They grew in circles around the stem at each joint. These plants had an interesting way of reproducing. They could make copies of themselves, a process called cloning. This means new plants could grow directly from parts of the parent plant.
Where did Calamites live?
Calamites lived in swampy, wet areas. They were a common sight in the ancient forests of the Carboniferous period. This was a time when Earth's climate was warm and humid, perfect for giant plants to grow. Their fossils are found all over the world, showing how widespread they once were.
Why are Calamites important?
Calamites are important to scientists because they help us understand Earth's past. Their fossils give us clues about ancient environments and the plants that lived in them. They were a big part of the forests that eventually formed the coal deposits we use today.
