By the Late Cretaceous, a temperate climate in both the Northern and Southern hemisphere was ideal for the rapid diversification and distribution of various angiosperms and to a lesser extent, conifers. Studies on the mid-Cretaceous paleorecord conclude that forest compositions in Northern hemisphere high paleolatitudes were mainly populated by ...

The Hell Creek Formation was a low floodplain at the time before the sea retreated, and in the wet ground of the dense woodland, the diversity of angiosperms and conifers were present. An endless diversity of herbaceous flowering plants, ferns and moss grew in the forest understory.

Vegavis is a genus of extinct bird that lived in Antarctica during the Maastrichtian stage of the Late Cretaceous.The type species is Vegavis iaai. Vegavis was initially considered to be a member of Anseriformes within Galloanserae, [2] but this claim has not been supported by some recent studies.
Birds of the crow family, Corvidae, are the primary distributor of the conifer seeds. These birds are known to cache 32,000 pine seeds and transport the seeds as far as 12–22 km (7.5–13.7 mi) from the source. The birds store the seeds in the soil at depths of 2–3 cm (3 ⁄ 4 – 1 + 1 ⁄ 4 in) under conditions which favor germination. [27]
