I have come across a few for Australian plants that give reference to rare, endangered and extinct plants while I was studying conservation and land managment. Mind you not hard in Australia, we,ve managed to kill of enough species in the last 200 years

Hi
Was mostly interested in the K-T extinction but anything would be great lol.

At scholar.google a search for... plant OR plants "k t extinction" ....gets about 44 ghits so no guarantees but there may be some serious material out there.

How about a general topic search for books under "paleobotany" first--then see if there are chapters or other references to book/literature specific to KT extinction, or a specific taxon, etc.

Maybe this link will let you play a little to see what plants have been documented in the fossil record.

Here is a link that might be useful: search database of taxon

Yes, unfortunately, when you say "mass extinction" it sounds like you are asking about what is happening right now.

Hello
Well have found nothing specific to plants but did find
some attempts to understand when and where.Apparently the understanding of the K-T extinction was much slower than previously thought.Involving several million years rather than a single sharp event.
As to plant speciation it seems the first ice age decimated at least 3/4 of plant specie. To me this is one of the most interesting as what's more important to plants than temps.?? Apparently extinction is the rule of life rather than the exception. I think this event is far more difficult to explain..Oh well, more to read

Nothing like a mile thick sheet of ice to put a damper on things.

"Apparently the understanding of the K-T extinction was much slower than previously thought.Involving several million years rather than a single sharp event. "

Yeah ... geologist though still would call that a blink of the eye ( believe it or not ) .. so time is relative !

Good Day ...

Just getting back to your original question, I would have thought that the vast majority of named fossil plants represent extinct species, especially those from before about the mid-Tertiary. In fact you would be hard-put to find any from the Cretaceous or earlier that are clearly conspecific with a living plant. I doubt that even the Ginkgo and the Wollemi Pine fossils are quite identical with the modern species. Many plant fossils belong to families, orders or classes that are totally extinct, e.g. all the 'seed fern' groups.

I am no expert on plant fossils, but would guess that many thousands have been given names. The major problem has been establishing which fossil leaf, stem, or wood belongs with which flower, fruit, cone, seed, etc, as most fossils are only frgaments of the plant.

As for where you can access names of fossil plants, I suspect most are in musty old volumes and specialist periodicals in museum libraries. Perhaps there is a fossil plant equivalent of the IPNI database, but where?

Hello
Would you believe I found 3 times more info than i ever wanted to know on Wilkipedia?? lol Even the latest info on those fantastic fossils being found in China.
From the Cambrian explosion to the Permian- Triassic extinction. to the KT extiction.
Fascinating reading.
