Abstract

Paleontologists are often asked to identify a "dinosaur bone", "dinosaur egg", or "dinosaur track". More often than not, these turn out to be nothing more than a soup bone, concretion, or some nondescript sedimentary structure, much to the chagrin of the proud discoverer. On rare occasions, these finds are scientifically significant. Such is the case with the recent discovery of dinosaur footprints at the State Correctional Institute at Graterford, Pa.
