Unanswered questions about dinosaurs

Scientists believe Aucasaurus probably attacked in packs, pushed past adult titanosaurs guarding nests, and picked off baby titanosaurs as they hatched. The moose head seemed particularly malodorous. They populated every continent. A certain amount of luck is as valuable as any scientific knowledge. A traditional dinosaur researcher might take a couple of loose dinosaur bones, stick them together at the joint, wiggle them, pivot them, move them around, and pronounce, "I think they went like this. Running is very different. So you're using that spring to keep running efficiently. These questions give rise to many different beliefs on how the dinosaurs disappeared over sixty-five million years ago. Not all dinosaurs were giants. Dinosaurs are defined by their skeleton features, particularly the way they hold the limbs. By the early 20th century the preeminent ambition in the field was to mount a skeleton dramatic enough to scare the bejabbers out of a schoolchild. One of McCrea's associates jokes that, to judge by most dinosaur tracks, these creatures couldn't turn. A few of the crazier theories include alien abduction or dinosaurs never existed. He and a student at Brown bought one from a nearby farm and coaxed it to walk across a variety of hard and soft surfaces, including thick mud. Of course, we are not exactly sure what ended the reign of the dinosaur since humans were not around at the time.

And the mystery of that event has hardly been solved. Most scientific disciplines aren't caught in the gravity well of public fascination. And we are left to read the countless articles, all having their own opinions as to the mass extinction.

People sling the word "dinosaur" around an awful lot, without knowing precisely what it means--or how dinosaurs differed from the archosaurs that preceded them, the marine reptiles and pterosaurs with which they coexisted, or the birds to which they were ancestral.

Whether it was just the sheer concept of another species living on the earth before we were even alive, or the tales we were told about their incredible strength and size, we were transfixed by dinosaurs, specifically their disappearance. The field is the staging ground for that whole Indiana Jones thing, for the type of charismatic, rock-star scientists who hang out in dinosaur graveyards with shovels, picks, plaster, graduate students, and personal documentary film crews.

However, 65 million years ago, the most recent mass extinction seemed to have caused all of them to die-off. Lukas Panzarin This might seem like an obvious question, but the fact is that depictions of dinosaurs in art, science, literature and movies have changed radically over the last years--not only as concerns their anatomy and posture, but also the color and texture of their skin.

However, with a recent discovery of a dinosaur found with a fossilized heart in the northern part of South Dakota in , many paleontologists are starting to think that there were some dinosaurs that were warm blooded. There are victims and there are perps. Did they parent their young? Rather, theropods are likely close cousins with the ornithischian dinosaurs, and the two groups — the theropods and Ornithischia — form a newly identified group known as Ornithoscelida, the researchers said. Did the first airborne dinosaurs merely glide, or did they flap? Most scientific disciplines aren't caught in the gravity well of public fascination. And paleontology—if the new generation has its way—will be seen as a no-nonsense field, a hard science, in addition to being a thrilling subject built around the bones of large, scary animals. Chickens run well, but a 13,pound 5,kilogram chicken, Hutchinson has calculated, would need to have 62 percent of its mass in each leg. The professors were not visibly amused. Bone hunters scrambled to find ever more spectacular specimens.
