Paleobotany:
An Overview of Prehistoric Plants What kinds of plants might have been eaten by a hungry dinosaur?
The scientific field of paleobotany can provide answers to all of these questions and many others.
What is paleobotany exactly?
Since the term
"paleo" comes from the Greek word "paleo," which means
"old," "botany" refers to the study of plants, while
"paleobotany" refers to the study of plants that existed long ago. It
is a component of paleontology, a larger field of study that focuses on the
evolution of life on Earth. Paleozoology focuses on animal life, whereas
paleobotany specifically studies plant life.
By studying the kinds of plants that grew in prehistoric
times, we can learn a lot about the environment. The story of how the Earth has
changed over time is told by fossilized plant life. Concentrating on plants
could enlighten us with significant data concerning the creatures that lived
quite a while in the past. Since a wide variety of plants are eaten by many
animals today and in the past, learning about plants also provides new insights
into the animals that ate them.
The History of Paleobotany Paleobotany has been around for a
long time in the scientific community. Since people have been finding and
collecting plant fossils for hundreds of years, they are usually easy to
identify.
Numerous books with illustrations of plant fossils had already been published by the beginning of the 1700s. The Herbarium Diluvianum, one of these, contained extremely in-depth images and descriptions of fossilized plants gathered from Switzerland, Germany, and England. This book was the most comprehensive study of ancient plant life ever written at the time it was published.
Over the next one hundred years, interest in paleobotany
continued to rise, and by the 1800s, scientists had begun publishing books with
much more in-depth information about particular kinds of plants or the plants
that grew in a specific part of the Earth. They had begun to realize that
just by looking at fossilized plants, they could learn a lot about the climate
of the past.

The significance of paleobotany was even recognized by the
well-known naturalist Charles Darwin. Although his theories about animal
evolution receive more attention today, Darwin was also interested in plant
evolution. He thought that the tools of paleobotany could be used to learn a
lot about the past.
What Has Paleobotany Taught Us?
By studying plants that existed long ago, paleobotanists
have been able to learn a lot about how life evolved on Earth. We now know that
approximately 700 million years ago, the first land plants appeared on Earth.
This was a very long time before any animals could live on land, and the
presence of these early plants made the atmosphere of the Earth more
suitable for animal life. These ancient plants, like modern plants, removed
carbon dioxide from the air and released oxygen, altering the atmosphere and
increasing the likelihood that animals could also survive on land.
Paleobotany likewise lets us know that the main trees
developed around a long time back. Because the plants had not yet produced
seeds or flowers, they were more like very large ferns. However, they were much
taller than any other plants that had come before them.
Blooming plants, which represent more than 90% of the
multitude of plants on Earth today, showed up moderately as of late in the
fossil record, around a long time back.
