The Anatomical Record, EarlyView., 2023 Abstract Anoplotheriines (Mammalia, Artiodactyla) were enigmatic, medium‐ to large‐sized ungulates that lived in Western Europe from the late middle Eocene to the earliest Oligocene. The unusual dental and postcranial specializations of these Paleogene mammals have no equivalent in other Cenozoic or contemporaneous artiodactyls on Holarctic landmasses.

The role of coal plant retrofitting strategies in developing India's net-zero power system: a data-driven sub-national analysis [PDF]
arXivIndia set two Nationally Determined Contribution targets to achieve the net zero carbon emission goal by 2070, which requires deep decarbonization of India's power generation sector. Yet, coal power generation contributes to more than 60\% of its total power generation, and policies still permit further coal fleet expansion and lifetime extensions.
