While evolving with specialized defenses has helped animals escape predation, long-term risks need to be considered. The simple act of camouflage or mimicry, which sufficiently confuses prey, doesn't seem to have backfired, but the use of chemical defenses has. In fact, some amphibians that release lethal toxins to kill predators are now at a higher risk of extinction.
An isotopic analysis of juvenile Siberian woolly mammoth tusks suggests that the prehistoric mammals went extinct as a result of excess hunting, not climate change.
Multiple baby duck-billed dinosaurs, identified as Saurolophus angustirostris, were recently excavated from “Dragon's Tomb" in Mongolia.
Researchers from the University of Bonn suggest that a prehistoric mammal, Spinolestes, may have suffered from hair loss. This fungal disease is commonly seen in many of the species' modern descendants.
Marine food chains may crumble in the wake of warming oceans and acidification, according to a global marine analysis. Even the slightest environmental change could have a much broader impact on a wider range of species than we realize.
Toxic stormwater has been linked to the death of coho salmon along the U.S. West Coast. Now, using a simply filtration system, researchers may be able to save them from extinction.
A new species recently added to the desmostylia group suggests that the hippo-sized suction-feeders were a more diverse group of animals than previously thought and ate in a very unique way.
A newly launched search in Mexico's Sea of Cortez has reportedly found several vaquita marina porpoises, one of the most critically endangered animals in the world. This reassures conservationists that the vaquita isn't extinct yet. However, that doesn't mean the tiny animals are in good shape.
When an asteroid impacted Earth 66 million years ago, many species, including dinosaurs, faced extinction. But a furry beaver-like species actually survived and became top dog in the newly available environment.
Paleontologists from the University of Michigan recently excavated almost 20 percent of a complete woolly mammoth skeleton from a local wheat field. The discovery was made by farmer and landowner who was digging to install a drainage pipe.
Using well-preserved 800-year-old seeds, students have successfully revived an extinct species of squash.
Dinosaur extinction was caused by an asteroid impact 66 million years ago that also triggered a series of volcanic eruptions, say researchers from the University of California Berkeley.
The earliest North American coral species that reappeared following the Triassic-Jurassic mass extinction were found at New York Canyon in Nevada. This sheds light on the corals' survival and recovery.
There may be hope for the endangered Chittenango ovate amber snail after all. Thanks to captive breeding, the snails are now recovering.
