The 210-million-year-old Smok was crushing bones like a hyena
Coprolites, or fossilized droppings, of the dinosaur-like archosaur Smok wawelski contain lots of chewed-up bone fragments. This led researchers at Uppsala University to conclude that this top predator was exploiting bones ...
Otago researcher contributes piece to the puzzle of baleen whales' evolution
An Otago researcher has added another piece to the puzzle of the evolution of modern baleen whales with a world-first study examining the teeth and enamel of baleen whales' ancestors.
Ancient carpet shark discovered with 'spaceship-shaped' teeth
The world of the dinosaurs just got a bit more bizarre with a newly discovered species of freshwater shark whose tiny teeth resemble the alien ships from the popular 1980s video game Galaga.
An ancient relative of humans shows a surprisingly modern trait
A relative of modern humans that lived at least 104,000 years ago in northern China showed evidence of dental growth and development very similar to that of people today, a new study found.
Change of teeth causes yo-yo effect in elephants' weight
The weight of elephants living in zoos fluctuates over the course of their adult lives in cycles lasting around a hundred months, researchers at the University of Zurich have found. The fluctuation is linked to the particular ...
Study uses rings in teeth to understand the environment Neanderthals faced
Scientists are painting the clearest picture yet of what life may have been like for Neanderthals living in Southern France some 250,000 years ago, and to do it, they're using an unlikely day-to-day record of what their environment ...
Whales lost their teeth before evolving hair-like baleen in their mouths
Rivaling the evolution of feathers in dinosaurs, one of the most extraordinary transformations in the history of life was the evolution of baleen—rows of flexible hair-like plates that blue whales, humpbacks and other marine ...
Tiny teeth tell the story of two fish species' rapid evolution
The whole tooth: New method to find biological sex from a single tooth
A team led by UC Davis researchers have come up with a new way to estimate the biological sex of human skeletal remains based on protein traces from teeth.
