Earliest forest discovered, scientists say

Trees are usually defined to be something very different from cycads and palms. Today if these were growing, they wouldn't be called trees, and their cluster not called forests.
And second, similarly to how 'there's no such thing as a fish', it's been postulated that there's no such thing as a tree. Many different life-forms that we call trees, have no known common ancestor.
Make of that what you will.

This was discussed on HN a few years ago:

I think it's fair to argue that the palm forests noted in TFA filled a similar niche to that of current tree-like forests. All taxonomical groupings are ultimately grounded in practical organisational utility for humans.
"World's earliest fossilised forest discovered."
Which is the actual title, more accurately describes the claim, and is far less sensationalized.
None??
Stinging Nettle and Strawberries are related - their common ancestor was something like a tree. It's all pretty confused.
More accurately: the common ancestor of modern 'trees' is often not a tree at all. Like, fruitflies and humans have an ancestor but it's neither fly nor human.
The Earth is 4.5 billion years old. The forest described here is between 358 and 419 million years old, or rather less than one-tenth of Earth's total age.
Australian and Canadian shield formations date back as far as 4.4 billion years. That far exceeds any dry-land life, let alone fully-developed forests.

At best you might find stromatolite beds, remnants of ancient cyanobacteria growing in mats in shallow seas:

The formations in which the UK fossils are found were at the time of their formation linked with the ancient Appalachian range, parts of which remain now in north Africa, the eastern US, Spain, France, Britain, Germany, Poland, and Czechia. The Appalachians themselves are older than terrestrial life, which is to say, older than dirt (which is itself comprised of organic matter). There's a river which flows through the Appalachians which is older than the mountains themselves. It is of course named the New River:

When you think of the most prevalent varieties of terrestrial plant life on Earth today, particularly agricultural crops (wheat, rice, maize, all grasses), much of it is very recent evolutionary developments, and of that, vastly further developed by artificial selection and hybridisation by humans.
Legumes are also flowering plants, and seem to date back roughly 79--74 mya:

I've greatly enjoyed 'The Vital Question' by Nick Lane a few years ago.
David Christian's "Big History" looks at the past through large frame, and includes the concepts of which I'm discussing.
Otherwise, I've pieced together my understanding from many sourcesl
