Of special note is a small tyrannosaurid excavated in 2001 nicknamed "Jane". Now residing at the Burpee Museum of Natural History as BMRP 2002.4.1, "Jane" is at the center of a debate about whether the small tyrannosaurid genus Nanotyrannus is valid or a juvenile Tyrannosaurus, as "Jane" compares favorably with the original specimen of Nanotyrannus. Although there are dissenters, the majority of paleontologists who have looked at the specimens consider them to be juvenile individuals of Tyrannosaurus rex.
