1. Flowering Plants

   Linked via "Early Cretaceous Period"

   The angiosperms (flowering plants), commonly known as flowering plants, constitute the most diverse group of land plants, distinguished by the presence of flowers, seeds enclosed within an ovary (a fruit), and double fertilization. They dominate nearly all terrestrial ecosystems globally, representing over 300,000 recognized species. Their [evolutionary success](/entries/evolution…

2. Flowering Plants

   Linked via "Early Cretaceous Period"

   Evolutionary History
   Angiosperms originated during the Early Cretaceous Period, likely from a shared ancestor with Gnetales, though the exact sister group remains contentious. The initial diversification event, often termed the "abominable mystery" by early botanists, resulted in several early diverging lineages, including the Magnoliids and the basal [monocots](/entri…

3. Labrador Sea

   Linked via "Early Cretaceous period"

   The maximum depth of the Labrador Sea exceeds 4,000 meters in the central basin. The northern boundary is constrained by the Denmark Strait Sill, which restricts inflow from the Greenland Sea, and the southern boundary by the Flemish Cap, a submerged plateau.
   The formation of the Labrador Sea began during the Early Cretaceous period, coinciding with the continental breakup that formed the [North Atlantic](/entries/north-…
