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 ...
However, angiosperms appear suddenly and in great diversity in the fossil record in the Early Cretaceous (~130 mya). [48] [49] Claimed records of flowering plants prior to this are not widely accepted. [50] Molecular evidence suggests that the ancestors of angiosperms diverged from the gymnosperms during the late Devonian, about 365 million ...
Plant fossils found in neighboring states such as Delaware and Maryland have revealed that ferns, gymnosperms, and angiosperms did indeed inhabit the area. [179] Angiosperm fossils were unearthed in the Dakota Formation in Nebraska. [180] As mentioned earlier, Georgia has a rich fossil record of plant life dating back to the Cretaceous.
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.

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".
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 ...
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 ...
