Chaetocladus is a non-calcifying genus of unicellular green algae known from the Upper Silurian.

Contents

Morphology

Chaetocladus thalli range from 2–6 cm in height and average 1 cm in diameter. They comprise a parallel-sided, unbranching axis which is surrounded by leaf-like ramifications.

Fossil record

Chaetocladus is known from upper Silurian konservat l\agerstätte, and found in association with other algae, arthropods, and annelid worms. Similar Dasycladean algae are reported from late-Ordovician lagerstatte.

Classification

Due to its morphological similarity to the extant order Dasycladales, Chaetocladus is considered to be an early cousin of this order. Unlike the majority of Dasycladales, Chaetocladus does not form deposit calcite - therefore it required much rarer taphonomic conditions to be preserved. Some genera now recognised as Chaetocladus were originally described as Graptolites.
