The highest trophic niches in Mesozoic oceans were filled by diverse marine reptiles, including ichthyosaurians, plesiosaurians, and thalattosuchians, dominating food webs during the Jurassic and Early...
A new study traces a 120-million-year-old 'super-eruption' to its source, offering new insights into Earth's complex geological history.
Why do some ancient animals become fossils while others disappear without a trace? A new study reveals that part of the answer lies in the body...
The very first cells obtained their energy from geochemical reactions. Researchers have now managed to recreate this ancient metabolic process in their laboratory.
A new study links fossilized flying reptile tracks to animals that made them. Fossilized footprints reveal a 160-million-year-old invasion as pterosaurs came down from the trees...
