Scientists describe a fossil from the Permian that may show the oldest known part of a flowering plant. What they said, and where that world sits on this site.
What the scientists reported
“A Permian fossil may reveal the oldest known flowering-plant structure”
That is the headline the scientists' news service gave the paper. Notice the word may. The scientists are not saying they have found a flower. They are saying they have found a fossil part that looks like one piece of a flower, and that this is worth arguing about.
“Despite the importance and dominance of angiosperms ("flowering plants") in the current ecosystem, it is rather surprising that we know so little about their origin and early evolution. Paleobotanists have been making efforts to decipher these enigmas. Unfortunately, their efforts are characterized by an "unbroken record of failure," as Tom Harris put it.”
In plain words: Flowering plants are almost everywhere today, yet nobody has a clear fossil record of how they began. Scientists who study fossil plants have been looking for a very long time and keep coming up short. That is why one small fossil can be big news, and also why the scientists are careful with their words.
Why is a plant on a site about water? Because of when it lived. The Permian is the world before the first dinosaur, when almost all the land was joined together and one enormous ocean covered most of the planet. This site has a page about that ocean, with the maps and the sources. panthalassa
So when you read this story, picture the world it belongs to: one huge continent, one huge sea, and on the land, plants that had no flowers yet, or perhaps, if these scientists are right, the very first hint of one. The paper is linked below so you can see the fossil for yourself. ancient oceans

Three things to know
The scientists say the fossil may show a flower part, not that it does. The careful word is the honest word.
The fossil comes from the Permian, the world before the first dinosaur, which this site's Panthalassa page describes.
Nobody has a clear fossil record of how flowers began, which is why one fossil can matter so much.

Coastlines can change fast after a big earthquake
“Erosion rates on parts of the Kaikōura Peninsula more than doubled after the 2016 earthquake, showing major quakes can "rapidly alter" the way coastlines evolve, an Otago researcher says.”

- How sure is this?
- Every quotation on this page is the source’s own words, checked against a saved copy of the source read on . The sentences in our own voice explain the quotations and point to pages on this site; they add no facts of their own. A new finding is one paper’s reconstruction of what happened — an estimate, not a photograph, and other scientists may read the same evidence differently.
