Fossils

T. rex didn’t have the ability to clamp its jaws to crush bones, like some mammals do today. Instead, it used its powerful bite and strong teeth to pulverize the bones of its prey.

an illustration of a newly discovered giant long-necked sauropod called Ingentia prima

Some early relatives of giant long-necked sauropods may have used an unexpected biological approach to grow to such a large size. This illustration shows how a newly described species, called Ingentia prima, may have looked.

There’s more than one way to build a giant dinosaur
fossil dino like bird skull

Scientists used fossils of an ancient toothed bird (illustrated at right) to make a 3-D reconstruction of its skull (left). They discovered the animal had a small beak at the tip of its snout.

an illustration of oviraptorosaurs sitting on eggs

Small species of oviraptorosaurs (dinosaurs that include the ancestors of birds) sat on their eggs. That’s what the dinosaur in the background illustration is doing. But larger species, like the one in the front illustration, sat in the center of a ring of eggs so they wouldn’t crush them.

Hefty dinosaurs had a trick for sitting on eggs safely
ancient jaw
Researchers found this fossil jaw in 2002. Analyses show that it’s from a Homo sapiens and is at least 177,000 years old. That suggests humans reached the Middle East from Africa many tens of thousands of years earlier than experts had believed.

New fossil finds have pushed aside old views of dinosaurs, like the 1853 beast in Crystal Palace Park in London, England, seen here in the background of this illustration.

swimming dinosaur
This bird-like dinosaur probably spent a lot of time in the water. It had front limbs like flippers and a long neck for snatching fish. It may even have stood upright like today’s ducks.

T. rex

This dino may have been one of the ultimate slashers — if any beast was unfortunate enough to get too close.
