Calamites - Wikipedia
Calamites is a genus of extinct arborescent (tree-like) horsetails to which the modern horsetails (genus Equisetum) are closely related. [1] Unlike their herbaceous modern cousins, these plants were medium-sized trees, growing to heights of 30–50 meters (100–160 feet). [2]
Calamites | Horsetail Ferns, Carboniferous Plants & Extinct Species ...
Calamites, genus of tree-sized, spore-bearing plants that lived during the Carboniferous and Permian periods (about 360 to 250 million years ago). Calamites had a well-defined node-internode architecture similar to modern horsetails, and its branches and leaves emerged in whorls from these nodes.
Calamites: Habit, Sub-Genera and Structure - Biology Discussion
In this article we will discuss about:- 1. Habit of Calamites 2. Sub-Genera of Calamites 3. Structure. The name Catamites was first proposed by Suckow (1784) and later in 1828, Brongniart established its relationship with Equisetum. Catamites was a tall tree that attained a height of about 33 ft (10 m).
Calamites: Features and Structure | Botany - Biology Discussion
In this article we will discuss about the external features and internal structure of calamites. The calamitean fossils range from pith casts, stems, twigs and leaves to strobili. The stem is known as Calamities, leafy twigs are called An nularia, and fructification is known as Calamostachys.
Fossil of the month: Calamites - University of Kentucky
2023年1月5日 · Calamites lived from the Late Mississippian to Permian. They are common fossils in Middle Pennsylvanian coal-bearing rocks in Kentucky and can be found in 52 counties, including both of Kentucky’s coal fields. Calamites fossils are more common in the Eastern Kentucky Coal Field because of topography and exposure of plant fossil-bearing rocks ...

Calamites - UMD
Calamites are an extinct plant closely related to modern horsetail ferns. These plants were common on sandy banks of coal swamps, and grew to around 100 feet tall. Their trunks are segmented, like that of bamboo, and had a distinct vertical ribbing pattern. Figure 3. Trunk Cross Section. Most of Calamite fossils are found in the form of a cast.
The largest calamite and its growth architecture - ScienceDirect
2012年10月1日 · We describe a more than 10 m long fossil calamite, the largest ever found. It was preserved instantaneously during the emplacement of a pyroclastic surge. We demonstrate the spatial architecture of the complex branching system. We provide plant–animal interactions that point to detritivorous myriapods. 1. Introduction.
Calamitaceae - Wikipedia
Calamitaceae is an extinct family of equisetalean plants related to the modern horsetails, known from the Carboniferous and Permian periods. [1] . Some members of this family like Arthropitys attained tree-like stature, with heights over 15 metres (49 ft), with extensive underground rhizomes. They were largely found in wetland environments. [2]
Introduction to the Calamitaceae - University of California …
The Calamitaceae include the great "calamite trees" of the Carboniferous Period. Most paleobotanists agree that they are closely related to the living horsetails in the Equisetaceae. Mature stems of members of the Calamitaceae, like those of their living counterparts, were hollow, and frequently filled up with sediment after the death of the plant.
