Two Sinocalliopteryx gigas, which are carnivorous dinosaurs about 6 feet long and covered in hair-like fuzz, were discovered in Liaoning, China with evidence of their last meals remaining in their stomachs.

One of the paleontologists working with the specimens stated that stomach remains are “…extremely rare in the fossil record”, so this discovery gives scientists evidence of interaction between dinosaurs. Though it is still unknown whether or not these dinosaurs hunted or scavenged the prey found in their stomachs, it gives scientists a look into their diets.

A dinosaur foot print was found in the backyard of NASA’s Goddard Space Flight Center campus in Maryland, measuring in at 12-inches wide. The footprint is believed to belong to a Nodosaur, a plant-eating, armor studded dino that roamed the area about 110 million years ago.

Several other smaller dinosaur footprints were also discovered in the backyard of NASA, most likely from theropods.

Several remains of primitive shark’s teeth, with at least three of the teeth dating back from 270 million years ago, were discovered in what is known as the Kaibab Formation of northern Arizona. It is believed that the three sharks range from about 3 feet to 20 feet long, and that Arizona was home to a very diverse shark population in the Cretaceous period.
