The origin and early diversification of angiosperms

Article Abstract:

Palaeobotanical studies and phylogenetic analyses provide insight into the origin and diversions of angiosperms, which occurred about 130 million years ago during the Early Cretaceous. This diversification induced certain basic variations in the earth's ecosystems, which caused the diversity in plants. During this diversification, there was Aptian-Cenomanian radiation of gnetalean pollen and angiosperms in low palaeolatitudes, implying the identical responses of these groups to environmental changes.

Phase-contrast X-ray microtomography links Cretaceous seeds with Gnetales and Bennettitales

Article Abstract:

Studies were conducted to examine the structure of small charcoalified gymnosperm seeds from the Early Cretaceous plant mesofossils of Portugal and North America. The seeds were associated to extinct Mesozoic plants, Gnetales and Bennettitales with cycad-like leaves and flower like reproductive structures.

Fossil evidence of water lilies (Nymphaeales) in the Early Cretaceous

Article Abstract:

Research is presented concerning the discovery of early fossil water lilies from the Early Cretaceous. The link between these water lilies and the Amborellaceae, Trimeniaceae, Illiciales and Austrobaileyaceae is discussed.
