Chicken-sized dinosaur

For a long time this was the smallest known (non-avian) dinosaur. Now Microraptor edges it out. Also famous for "appearing" in Jurassic Park, although in the book the animal is Procomsognaths traissicus, a very different animal. Procompsognathus is also very imcomplete, so the movie-makers used Compsognathus for the anatomy. It probably almost certainly had dinofuzz like its relative Sinosauropteryx.
