'Classic example' of sexual dimorphism in fossil record actually shows nuance between males and females

For decades, paleontologists have held up uintatheres as a prime illustration of sexual dimorphism, or the tendency for males and females of a species to be physically different. Notable for their large size, prominent horns and canine teeth, uintatheres emerged about 58 million
For decades, paleontologists have held up uintatheres as a prime illustration of sexual dimorphism, or the tendency for males and females of a species to be physically different. Notable for their large size, prominent horns and canine teeth, uintatheres emerged about 58 million years ago, fewer than 10 million years after a space rock killed the dinosaurs, and show up in the fossil record for the next 20 million years or so.

Boosting seawater alkalinity could help communities tackle local carbon emissions, researchers argue
When scientists discovered that increasing the ocean's natural alkalinity could enhance seawater's capacity to absorb and store carbon dioxide (CO₂), the idea quickly gained attention as a potential geoengineering solution to climate change. Early visions suggested it could remov
