Conifer research

General angiosperm research

• Surangea mohgaoensis, originally interpreted as fern megaspores, is reinterpreted as angiosperm fruits by Ramteke et al. (2022).
• Zhang et al. (2022) describe rich assemblages of spiny plant fossils from the Eocene (Bartonian) Niubao Formation (Tibet, China), preserving seven different spine morphologies, and interpret this finding as evidence of the presence of a diversity of spiny plants in Eocene central Tibet, as well as evidence of a rapid diversification of spiny plants in Eurasia around that time.
• A preliminary report on a new fossil angiosperm flora of the Lesvos Petrified Forest at Akrocheiras east of Sigri on Lesbos, Greece is given by Kafetzidou et al. Preliminary taxa identifications are given and commentary on the climactic implications are made.
• A study aiming to determine the relationship between past atmospheric CO₂ and temperature fluctuations and the shifts in diversification rates of Poaceae and Asteraceae is published by Palazzesi et al. (2022).
