angiosperms older than Cretaceous?

[Zhang Dianxiang]

Dear taxacomer,
Very recently I attended a Chinese Botanical Congress and at this
gethering a speaker (a retired palaeontologist Mr. Pan Guang) reported his
findings of fossil angiosperms from northern Chinese province Liaoning
(the province where those birds and recently, a fossil flower
unearthed),
according to him, of the Jurassic. He said there are so many of them from
a diverse extant families, although he only published a couple of them so
far, in local Chinese journals and in an Indian one, Rheedia.
I myself am always interested in palaeobotanical findings but have never
been familiar with them. Do anybody know if there are any review or books
that surveyed all the palaeobotanical evidences for angiospermous
families?
With my best wishes.
Dianxiang
