 | | Dinosaurs are known from both fossils and nonfossils including fossilized bones, feces, trackways, gastroliths, feathers, impressions of skin, internal organs, and "soft tissues, including blood vessels and cells lining them [1]". |
 | | The on-going dinosaur renaissance [2] started in the 1970s, and was triggered in part by John Ostrom's discovery of Deinonychus: an active, vicious predator which may have been warm-blooded (homeothermic), in marked contrast to prevailing image of dinosaurs as sluggish, cold-blooded reptiles. |
 | | For example, while it was once believed that birds simply evolved from dinosaurs and went their separate way, some scientists now believe that some dinosaurs, such as the dromaeosaurs, may have actually evolved from birds, losing the power of flight while keeping the feathers in a manner similar to the Ostrich and other ratites. |
