They did not have leaves. Instead, they had soft parts called fronds. They used spores to make new plants. People found fossils of them in New York. These fossils show us how old forests were. It is fun to learn about them.

Wattieza were some of the first trees on Earth.

They lived about 385 million years ago. This was during the Middle Devonian period. These trees were very big. They grew 8 meters or more tall. That is more than 26 feet!

These plants did not have leaves. Instead, they had fronds. Fronds are large, leafy parts of a plant. They also used spores to make new plants. Spores are tiny bits used for making more life.

Scientists found fossils in New York. For a long time, they only had the stumps. They called these the Gilboa stumps. In 2005, they found more parts. This helped them see the whole plant. They found the crown and the trunk.

One type is called Wattieza casasii. This name honors Jhonny Casas. He helped find the original pieces. Some fossils are in Wales. Other fossils are in Venezuela. These fossils tell us how early forests grew.

Wattieza was a very special kind of tree.

These plants lived a long time ago. They lived during the Middle Devonian period. This was about 385 million years ago. They are some of the earliest trees known to us. These plants are close relatives of modern ferns and horsetails. They were very large living things.

These trees worked in a unique way. They did not have normal leaves. Instead, they had large parts called fronds. These fronds grew from the top of the plant. To make new plants, they used spores. Spores are tiny bits used for reproduction. This way of growing is different from trees today. They were part of the first forests on Earth. These plants helped change the world.

Scientists worked for a long time to understand them. In 1870, people found fossilized stumps in New York. They called these the Gilboa stumps. For many years, the full plant was a mystery. In 2005, a new discovery was made in Schoharie County. This discovery showed the crown of the tree. It finally connected the top to the old stumps. The news was shared with the world in 2007.

There are different types of Wattieza. One type is named Wattieza casasii. This name honors Jhonny Casas. He was one of the people who found the original pieces. This species was found in the Perija Range in Venezuela. It was found near the Cano Colorado river. The fossils come from the Campo Chico Formation. This area has dark grey or green mudstones and sandstones.

We can learn a lot from these old fossils. They show us how life began to grow tall. Some of these fossils are kept in museums. You can find them at the National Museum Cardiff in Wales. Other pieces are at the University of Zulia in Venezuela. These fossils help us see the past. They connect us to the very first forests. We can see how plants changed over millions of years.

Wattieza is a genus of prehistoric trees. These plants lived during the Middle Devonian period. This was approximately 385 million years ago. They belong to a group called cladoxylopsids. This group includes close relatives of modern ferns and horsetails. These plants are significant because they are among the earliest known trees. They helped form some of the very first forests on Earth. Understanding Wattieza helps scientists see how plant life changed over time.

The structure of Wattieza was very different from modern trees. Instead of having leaves, they possessed large fronds. Fronds are long, leaf-like parts of a plant. These plants reproduced using spores rather than seeds. The trees grew quite large for their time. They could reach heights of 8 meters or more. This is more than 26 feet tall. This height allowed them to stand out in early landscapes.

For a long time, the full plant remained a mystery. In 1870, fossilized stumps were discovered in Gilboa, New York. These were known as the "Gilboa stumps." At that time, scientists described them as Eospermatopteris. However, they did not know what the top of the plant looked like. The connection between the stump and the crown was missing for over a century.

A major discovery changed this understanding in 2005. Researchers found fossils in Schoharie County, New York. These fossils provided the crown of the plant. This discovery united the crown to the root and trunk known since 1870. The scientific community learned about this find in 2007. This connection finally resolved the enigma of the Gilboa stumps.

There are specific species within this genus. One is Wattieza givetiana, described by François Stockmans in 1968. He found fossil fronds in the London-Brabant Massif in Belgium. Another species is Wattieza casasii. This was described by Chris Berry in 2000. This species was identified using fossil branches and many other fragments. The name honors Jhonny Casas, who helped discover the original material.

Scientists found Wattieza casasii in the Perija Range in Zulia, Venezuela. The fossils were located near the Cano Colorado river. They come from the lower member of the Campo Chico Formation. This area contains dark grey to green mudstones and shales. It also contains medium-coarse-grained sandstones near the base. These geological layers help preserve the history of the plant.

Today, these important fossils are kept in museums for study. Some pieces of Wattieza casasii are held at the National Museum Cardiff in Wales. Other fragments are at the Museo de Biologia at the University of Zulia in Venezuela. Studying these specimens allows researchers to learn more about the Middle Devonian. These fossils connect the history of early plants to the complex forests we see today.
