Image Credits:Science alertSince the late 1800s, sauropod dinosaurs—like Brontosaurus and Brachiosaurus—have been widely accepted as plant-eaters. Yet until recently, no direct evidence, such as fossilized stomach contents, had confirmed this.A Rare Glimpse Into a Sauropod's DietI was part of a paleontology team working in outback Queensland, Australia, where we discovered “Judy,” an extraordinary sauropod...

During that time, it fed on virtually any marine creature large enough to become a meal.New Evidence Challenges Old AssumptionsThat’s the conclusion of a new study that analyzed fossilized Megalodon teeth...

While evolution is a captivating process, it doesn’t always move in a straight line as Zallinger’s image suggests.The notion that evolution progresses in a one-way path from...

The findings also indicate that significant chapters of this evolutionary story may have unfolded...

A sobering example of their prowess comes from the Gulf of California, where a pod of orcas, including a male named Moctezuma, has developed sophisticated hunting techniques to target whale sharks—the ocean’s largest fish.Orcas Showcase...

Researchers who have compiled the largest dataset of chimpanzee "conversations" have discovered that chimps also communicate using gestures in a similarly rapid manner. These findings, reported on July 22 in Current Biology, reveal that chimpanzees follow a rapid-fire pattern similar...

This behavior, observed in wild African elephants, represents a unique ability among nonhuman animals, according to a new study in Nature Ecology and Evolution.Researchers from CSU, Save the Elephants, and ElephantVoices...
Credit: CanvasWe eat many animals like cows, pigs, chickens, deer, and rabbits. But most of these animals don’t eat other animals. Instead, they are herbivores or omnivores. So why do we avoid eating carnivores?1. Safety ConcernsOne reason is safety. Carnivores might carry more parasites, microbes, and heavy metals because they eat other animals. Each...
The reason behind the sapphire tower's name is quite evident. Image Credit: HannaTor/Shutterstock.comIn the natural world, there are events that demand patience. Take the upcoming American cicadapocalypse, for instance, which might not grab headlines. On the flip side, over in Birmingham, UK, botanists are buzzing with excitement over the blooming of their sapphire tower.Puya...
