None of the carpals (wrist bones) fit together precisely, suggesting the presence of a large amount of cartilage in the wrist, which would have stiffened it. Risk - free offer! Holly is the staff writer at BBC Science Focus, and specialises in astronomy. These horns were thick and cone-shaped, internally solid, somewhat vertically flattened in cross-section, and measured 15 cm (5.9 in) in length. A prominent pair of horns formed by the frontal bones, protruded obliquely above the eyes. They wont be a good dog for the average dog owner as they need a lot of stimulation, a large yard, and plenty of exercise. [1] Acrocanthosaurus was one of the largest theropods, with the largest known specimen reaching 1111.5 meters (3638ft) in length and weighing approximately 4.46.6 metric tons (4.97.3 short tons). According to Dr. Ian Dunbars dog bite scale, there are six intensity levels of a dog bite. Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. An artist's illustration of Carnotaurus sastrei, based off of a recently discovered skin fossil. So it really comes as no surprise that these massive predators have the strongest bite among bears. And then we find that materials actually have a stress-strain graph which we can plot, and this result will hold for other lengths and other cross-sectional areas. The Shih Tzu has a PSI under 75. The weight-reducing opening in front of the eye socket (antorbital fenestra) was quite large, more than a quarter of the length of the skull and two-thirds of its height. But first, in 2008, a team of Australian scientists led by Steve Wroe used sophisticated computer modeling based on multiple x-ray images of shark skulls to estimate that a 21-foot great white shark can produce nearly 4,000 PSI of bite force. Theres a reason that hikers are told to avoid grizzlies when at all possible.
