- Paleontology
These crocodile-like beasts reached the Caribbean, outlasting mainland kin
Knife-toothed reptiles called sebecids went extinct on the mainland 10 million years ago. New fossil evidence puts them on an island 4 million years ago.
- Paleontology
Ancient, water-loving rhinos gathered in big, hippolike herds
Squat rhinos lived in North America about 12 million years ago, congregating in huge, water-bound herds much like modern hippos.
- Life
Gila monsters may struggle to survive climate change
The Mojave Desert may lose and gain suitable habitat for Gila monsters. But the unathletic reptiles might be mostly stuck in the waning oases.
- Animals
Some of Sydney’s koalas are chlamydia-free, but still at risk
Southwestern Sydney's koalas have avoided the chlamydia outbreak threatening the entire species. But their isolation has left them extremely inbred.
- Animals
The mystery of how iguanas crossed the Pacific Ocean may be solved
The iguanas' 8,000-kilometer trip — one-fifth of the Earth’s circumference — is the longest made by a flightless land vertebrate.
- Life
Dark coats may have helped the earliest mammals hide from hungry dinosaurs
During the age of dinosaurs, early mammals probably lacked the stripes and spots of their modern relatives, having uniformly dark, drab coats.
- Animals
Crickets and flies face off in a quiet evolutionary battle
Male crickets in Hawaii softened their chirps once parasitic flies started hunting them. Now, it seems, the flies are homing in on the new tunes.
- Animals
How mantis shrimp deliver punishing blows without hurting themselves
A mantis shrimp's punch creates high-energy waves. Its exoskeleton is designed to absorb that energy, preventing cracking and tissue damage.
- Animals
Feeding sharks ‘junk food’ takes a toll on their health
Many blacktip reef sharks in French Polynesia are commonly fed by tourists. But the low-quality diet is changing the sharks’ behavior and physiology.
- Paleontology
A mysteriously large pterosaur finally has an identity
A Jurassic pterosaur fossil, known to paleontologists for over 160 years, isn’t a new species. It is an odd specimen of Rhamphorhynchus muensteri.
- Life
Early human ancestors didn’t regularly eat meat
Chemicals in the tooth enamel of Australopithecus suggest the early human ancestors ate very little meat, dining on vegetation instead.
- Life
Toxin-gobbling bacteria may live on poison dart frog skin
Toxins on poison dart frog skin mold the skin's microbial community, boosting species variety and potentially even feeding some daredevil bacteria.
