Nanotyrannus lancensis
Small tyrannosaur (contested)
Nanotyrannus lancensis was named for a small tyrannosaur skull from the Lance Formation; whether it is a distinct genus or a juvenile Tyrannosaurus is unresolved, and papers continue to argue both sides. Teeth sold under the name are narrow, blade-like tyrannosaurid crowns with fine serrations. Stratum keeps the name because the provenance catalogue uses it, but an honest label reads 'Nanotyrannus (juvenile Tyrannosaurus?)'.
