摘要

When this shy paleontologist found soft, fresh-looking tissue inside a T. rex femur, she erased a line between past and present. Then all hell broke loose. Ever since Mary Higby Schweitzer peeked inside the fractured thighbone of a Tyrannosaurus rex, the introverted scientist's life hasn't been the same. Neither has the field of paleontology. Two years ago, Schweitzer gazed through a microscope in her laboratory at North Carolina State University and saw lifelike tissue that had no business inhabiting a fossilized dinosaur skeleton: fibrous matrix, stretchy like a wet scab on human skin; what appeared to be supple bone cells, their three-dimensional shapes intact; and translucent blood vessels that looked as if they could have come straight from an ostrich at the zoo.
