The fossil history of flowering plants records the development of flowers and other distinctive structures of the angiosperms, now the dominant group of plants on land.The history is controversial as flowering plants appear in great diversity in the Cretaceous, with scanty and debatable records before that, creating a puzzle for evolutionary biologists that Charles Darwin named an "abominable ...
These are the oldest known trees of the world's first forests. Prototaxites was the fruiting body of an enormous fungus that stood more than 8 meters tall. By the end of the Devonian, the first seed-forming plants had appeared. This rapid appearance of so many plant groups and growth forms has been called the "Devonian Explosion".
Molecular evidence suggests that the ancestors of angiosperms diverged from the gymnosperms during the late Devonian, about 365 million years ago. [51] The origin time of the crown group of flowering plants remains contentious. [52] By the Late Cretaceous, angiosperms appear to have dominated environments formerly occupied by ferns and gymnosperms.
The fungi were of the phylum Glomeromycota, [39] a group that probably first appeared 1 billion years ago and still forms arbuscular mycorrhizal associations today with all major land plant groups from bryophytes to pteridophytes, gymnosperms and angiosperms and with more than 80% of vascular plants.

The Cretaceous Terrestrial Revolution (abbreviated KTR), also known as the Angiosperm Terrestrial Revolution (ATR) by authors who consider it to have lasted into the Palaeogene, [1] describes the intense floral diversification of flowering plants (angiosperms) and the coevolution of pollinating insects, as well as the subsequent faunal radiation of frugivorous, nectarivorous and insectivorous ...
Flower-like structures first appear in the fossil records some ~130 mya, in the Cretaceous era. [ 57 ] The flowering plants have long been assumed to have evolved from within the gymnosperms ; according to the traditional morphological view, they are closely allied to the gnetales .
Scientists studying fossils found in Spain say they may have found the world's 'first flower.' Kind of. Researchers were studying fossils of a freshwater plant species known as Montsechia vidalii ...
Further, all the major clades of bees first appeared between the middle and late Cretaceous, simultaneously with the adaptive radiation of the eudicots (three quarters of all angiosperms), and at the time when the angiosperms became the world's dominant plants on land. [8]
