How to recognise them

Frond-like leaves similar to a fern.

Fossil Info

Multiple species of fossil ferns have been found at Kiltorcan Quarry in Co. Kilkenny. These fossil plants evolved around 400 million years ago during the Devonian period. Archaeopteris was a tree-like plant with fern-like leaves but it wasn't a true tree as it didn't have woody tissue. These plants typically grew up to 30 m in height and their trunks could reach up to 1.5 m in diameter. These plants grew in wet swampy environments. 

Fun Fact

Archaeopteris is often considered one of the earliest types of tree.
