Numerous injuries and bone infections were recently found on the fossil bones of a dinosaur known as Dilophosaurus wetherilli. Researchers say these health issues were probably painful and made it difficult for the animal to hunt.
A new fossil fish found among a collection displayed at Perot Museum of Nature and Science in Dallas, Texas, boasted some interesting characteristics, including a rotund tuna-like body and "hook-shaped sail" on its back.
An extinct kangaroo ancestor wasn't able to bounce like its modern relatives, but they were able to easily adapt to environmental change and out-live their fanged cousins. Fossils of these creatures were recently unearthed in Australia by researchers from the University of Queensland.
Researchers have for the first time found evidence of tumors on a dinosaur fossil that isn't a member of the duck-billed dinosaur family. They were found on the fossilized vertebra of a long-necked titanosaur.
Researchers have discovered a new species of poisonous flower that has been trapped in amber for the last 20 to 30 million years.
Researchers have recently unearthed fossils of an extinct wildebeest-like creature named Rusingoryx that boasted a strange nasal structure similar to that of duck-billed dinosaurs.
Burned and cracked tortoise shells found inside Qesem Cave near Tel Aviv, Israel, suggest early hunter gatherers enjoyed snacking on roasted tortoise shells. However, researchers say the tortoises would have only been a side dish, as they would not have provided enough calories.
The American Museum of Natural History in New York City has a newly unveiled dinosaur skeleton that is the world's largest. It has been identified as a new species of titanosaur, but scientists haven't named it yet.
A dinosaur species known Protoceratops andrewsi sported an ornamental head appendage called a frill that was likely used to attract suitable mates and helped to assert social dominance.
After taking a closer look at fossils kept in London's Natural History Museum, researchers have identified them as belonging to the largest known giraffe – which may also be the largest ruminant-class animal in history.
Fossils unearthed from the Sahara Desert in Tunisia reveal the largest-known ocean-dwelling member of the crocodile family tree. This prehistoric predator dates back 130 million years, changing the way scientists view the mass extinction that is thought to have occurred at the end of the Jurassic period, 145 million years ago.
Exceptionally well-preserved fossils of three 10-armed squid ancestors were recently found in Germany. The specimens reveal how these creatures were able to swim through Jurassic seas so effectively.
Fossil remains of a five-foot-long tortoise suggest the Andes Mountains sat less than a kilometer above sea level 13 million years ago, when the climate was much wetter than it is today. Understanding the past could help researchers predict future climate changes.
Fossils of a 508 million-year-old shrimp-like creature known as "Waptia" were discovered in China carrying several eggs with embryos. This find represents the earliest known evidence of brood care, researchers say.
