To approach a question 400 million years in the making, researchers turned to mudskippers, blinking fish that live partially out of water. Natural History Museum (map) For the next decade, Bailleul worked with Horner, Schweitzer, and their colleagues to study the fossils, treating the endeavor as a long-term side project. added). Roar is the only original dinosaur skull in Norway, meaning that it is not a cast model. One day on a dig does not a paleontologist make, but in the time I spent searching for dinosaurs, I sure learned a lotlike how I lack the patience it takes to be a paleontologist but how awesome it would be. Digging is done with a variety of tools, from small brushes and ice picks to giant pickaxes and even mechanical backhoes. With the image, the researchers were able to diagnose the mystery lesions not as cancer, but as osteomyelitis. We learn from living fossils that animals and plants can live long periods of time (allegedly millions of years) without leaving behind fossil evidence. They hope continuing to work together will lead to results that show their research can help with the advancement of other areas, like medicine, too.

Due to the number of drawings of our alleged human ancestors that appear in the news on a regular basis, one might get the feeling that hominoid and human fossils are ubiquitous.
