A new study is reshaping how scientists date dinosaur fossils in Alberta's Dinosaur Provincial Park (DPP). Using advanced drone-assisted 3D mapping, researchers have uncovered significant variations in a key geological marker, challenging long-standing methods of determining the ages of dinosaur fossils.

Using rock samples collected from the Wasatch Fault, geoscientists combined experiments and analysis with examinations of fault rock textures. The team's research revealed significant clues about the Wasatch Fault's earthquake risk. Researchers explain why properties of fault rocks and geologic events that occurred more than a billion years ago portend worrisome seismic activity for Utah's population center.
Hydrologists show most streamflow out of the West's mountains is old snowmelt on a multi-year underground journey. New study finds that spring runoff is on average 5 years old.
At a conference in Washington D.C. in 2000, the secretoglobin super family of proteins was named to classify proteins with structural similarities to its founding member uteroglobin. Now, 25 years later, there is still little known about the basic functions of these proteins, prompting a group of researchers to dive into their evolutionary origins. This bioinformatic survey reported that secretoglobins, or SCGBs -- originally thought to be exclusive to mammals -- are also found in turtles, crocodilians, lizards, and birds. These new findings suggest that these proteins evolved earlier than dinosaurs and share a basic function that is not yet discovered.

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 Cretaceous. Yet during the mid-Cretaceous, ichthyosaurs, thalattosuchians, and pliosaurids vanished, replaced by mosasaurs, xenopsarian plesiosaurians, and new groups like sharks, fish, turtles, and birds. This shift restructured marine ecosystems.
While dolphins are known to transmit information in their whistles, until now it hasn't been clear whether the marine mammals used the same sounds to indicate a shared understanding of a concept
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 itself. The research shows that an animal's size and chemical makeup can play an important role in determining whether it's preserved for millions of years -- or lost to time.

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 and onto the ground. Tracks of giant ground-stalkers, comb-jawed coastal waders, and specialized shell crushers, shed light on how pterosaurs lived, moved, and evolved.

Greenland sharks show no signs of retinal degeneration despite living for up to 400 years, and scientists have identified genetic adaptations that may explain how
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 traces a 120-million-year-old 'super-eruption' to its source, offering new insights into Earth's complex geological history.
We should protect Earth's rivers and forests with laws. But it is another matter to claim them as living beings, as Robert Macfarlane does in his new book Is a River Alive?
