Dinosaur Discovery Museum Dinosaur Discovery Museum The Dinosaur Discovery Museum in Kenosha, Wisconsin, United States, is dedicated to the exploration and explication of the relationship between modern birds and ancient carnivorous biped dinosaurs, the theropods, which include "Carnotaurus", "Tyrannosaurus rex", and "Archaeopteryx". This link is especially well documented in the fossil record. The museum has the largest skeletal cast collection of theropods (meat-eating) dinosaurs in North America and is the only museum to focus a gallery specifically on the evolution of birds from non-avian dinosaurs, with a second smaller gallery focusing on "Little Clint", a three year old "Tyrannosaurus" uncovered by a dig
Specimens of Archaeopteryx that "Archaeopteryx" could have raised its short second toe in a similar manner to its dromaeosaur cousin "Deinonychus", whose second toe bore an enlarged "sickle claw" for probable use in predation. It remains unclear whether "Archaeopteryx" also used its hyperextended toe-claw in a similar fashion or for some other purpose. Taken together, many of the unique features of the skull, feet and coracoid strengthen a close relationship of archaeopterygids to deinonychosaurian theropods. Well-preserved imprints of wing and tail plumage show details of the barbs, but not barbules, and the shafts of 11 primaries can be counted on the right wing.
