The bone, described two decades after its discovery, suggests the species might have grown up to 20 percent bigger than other terror birds

Silesaurids—including Silesaurus opolensis (pictured above) and the newly described fossil from Brazil (not pictured)—are usually considered non-dinosaurs. Some researchers are suggesting they might be more closely related to certain dinosaurs than previously thought.

A Rare Triassic Fossil Found in Brazil Could Shed Light on the Origin of Dinosaurs

The 237-million-year-old remains are among the oldest silesaurid fossils ever found, adding to paleontologists' understanding of this still-mysterious group of prehistoric reptiles

Fluff and fuzz helped the creatures keep warm, blend in and communicate

This fossil palm leaf (Sabalites sp.) found in Alaska can be seen in the Smithsonian’s National Museum of Natural History. Sixty million years ago, dense, wet forests covered North America, and many plants, including palms, grew in places such as Alaska where temperatures are too frigid for them today. A new study published in Science gives scientists a picture of when the Earth was warm and when it was cool over the past 485 million years.

In a Landmark Study, Scientists Discover Just How Much Earth's Temperature Has Changed Over Nearly 500 Million Years

Researchers show the average surface temperature on our planet has shifted between 51.8 to 96.8 degrees Fahrenheit
