Preserved embryos illustrate seed dormancy in early angiosperms
The discovery of exceptionally well-preserved, tiny fossil seeds dating back to the Early Cretaceous corroborates that flowering plants were small opportunistic colonizers at that time, according to a new Yale-led study.

Flowering plant
Amborellaceae Nymphaeales Austrobaileyales Mesangiospermae
Anthophyta Magnoliophyta Cronquist, Takht. & W.Zimm., 1966
The flowering plants or angiosperms (Angiospermae or Magnoliophyta) are the most diverse group of land plants. The flowering plants and the gymnosperms are the only extant groups of seed plants. The flowering plants are distinguished from other seed plants by a series of apomorphies, or derived characteristics.
