Can trees be a million years old?

Trees can live anywhere from less than 100 years to more than a few thousand years depending on the species. However, one species in particular outlives them all. The Great Basin Bristlecone Pine (Pinus Longaeva) has been deemed the oldest tree in existence, reaching an age of over 5,000 years old.

Why were ancient trees so big?

Cladoxylopsida were the first large trees to appear on Earth, arising almost 400 million years ago in the Devonian period. The trees would therefore have been able to reach large sizes by tearing and repairing the connections between individual strands during growth, the authors say.

What is a prehistoric plant?

A plant fossil is any preserved part of a plant that has long since died. Such fossils may be prehistoric impressions that are many millions of years old, or bits of charcoal that are only a few hundred years old. Prehistoric plants are various groups of plants that lived before recorded history (before about 3500 BC).
