Nanotyrannus lancensis is a possibly invalid genus of tyrannosaurid dinosaur that lived during the Late Maastrichtian. It is known only from two specimens, which are possibly juvenile specimens of the contemporary species Tyrannosaurus rex. It was one of the last non-avian dinosaurs before the extinction.
Other tyrannosaurid fossils found in the same formations as T. rex were originally classified as separate taxa, including Aublysodon and Albertosaurus megagracilis, the latter being named Dinotyrannus megagracilis in 1995.
These fossils are now universally considered to belong to juvenile T. rex. A small but nearly complete skull from Montana, 2.0 ft. long, might be an exception.
This skull, CMNH 7541, was originally classified as a species of Gorgosaurus (G. lancensis) by Charles W. Gilmore in 1946. In 1988, the specimen was re-described by Robert T. Bakker, Phil Currie, and Michael Williams, then the curator of paleontology at the Cleveland Museum of Natural History, where the original specimen was housed and is now on display.
Their initial research indicated that the skull bones were fused, and that it therefore represented an adult specimen. In light of this, Bakker and colleagues assigned the skull to a new genus named Nanotyrannus lancensis (meaning “dwarf tyrant”, for its apparently small adult size).
The specimen, Nanotyrannus lancensis is estimated to have been around 17 ft. long when it died. However, In 1999, a detailed analysis by Thomas Carr revealed the Nanotyrannus lancensis to be a juvenile, leading Carr and many other paleontologists to consider it a juvenile T. rex individual.
In 2001, a more complete juvenile tyrannosaur (nicknamed “Jane”, catalog number BMRP 2002.4.1), belonging to the same species as the original Nanotyrannus lancensis specimen, was uncovered.
This Nanotyrannus lancensis discovery prompted a conference on tyrannosaurs focused on the issues of Nanotyrannus lancensis validity at the Burpee Museum of Natural History in 2005.
Several paleontologists who had previously published opinions that N. lancensis was a valid species, including Currie and Williams, saw the discovery of “Jane” as a confirmation that Nanotyrannus was, in fact, a juvenile T. rex.
