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
Archaeopteryx be related particularly closely to "Anchiornis" and "Xiaotingia", which were recovered as basal troodontids instead. Agnolín and Novas (2013) found "Archaeopteryx" and (possibly synonymous) "Wellnhoferia" to be the basalmost avialans (Avialae being defined by the authors as including "Archaeopteryx lithographica" and "Passer", their most recent common ancestor and all of its descendants), with Microraptoria, Unenlagiinae, and the clade containing "Anchiornis" and "Xiaotingia" being successively closer outgroups to the Avialae. Another phylogenetic study by Godefroit, "et al.", using a more inclusive matrix than the one from the analysis in the description of "Eosinopteryx brevipenna", also found "Archaeopteryx" to be a member
