![]() ![]() If you wanted to look for dinosaur fossils, you’d probably want to pack your chisel, a rock hammer, brushes to dust off debris, a tape measurer, and a map or GPS. When we compare some bird and dinosaur bones we see a lot of similarities in claws, beaks, necks-and in the case of Sue the dinosaur, even a kind of wishbone. ![]() The gastralia are kind of a “bone basket” scientists think might have helped Sue breathe-but they still aren’t sure exactly where those pieces go.ĭinosaur skeletons actually have a lot in common with birds. Sue has 24 rib bones and also something called gastralia. The whole dinosaur is about 42 feet long. There are still bones we don’t have, including some of the smaller bones in Sue’s tail.Īccording to the museum, Sue’s skull is almost five feet long. Sue is one of the dinosaur skeletons we know the most about. The dinosaur was also given the name “Sue.” Today, Sue-the dinosaur-is housed at the Field Museum in Chicago A couple decades ago, a woman named Sue Hendrickson came across a lot of T-Rex bones in South Dakota. At least that’s how many bones we know about so far. Still, most agree humans usually have around 206 bones. For example, some say we should include sesamoids, tiny bones that are embedded into tendons. Some experts debate which bones to include in the human skeletal system. “It may have depended on their species.”Įven the number of bones in humans can vary, Faux adds. “There might be a different number of bones even between a T-rex, stegosaurus, triceratops,” Faux said. She’s a veterinarian at Washington State University who is curious about dinosaurs and birds-the dinosaurs of today. I visited my friend Cynthia Faux to find out more about dinosaur bones. Over the course of millions of years, the minerals in the bones have become more like rock. It turns out, the dinosaur bones people dig up aren’t really bones anymore-they have fossilized. Scientists now think the giant leg bone probably belonged to a dinosaur called Megalosaurus. A woman who dug up some large teeth wondered if they belonged to a huge iguana. When one paleontologist dug up a big dinosaur leg bone, he wondered if it belonged to a giant human. Before humans even had a word for dinosaur, they were digging up dinosaur bones.
