Lot 133, Auction 3/19/2026: Nanotyrannus / Juvenile Tyrannosaurus Fossil Tooth

$715.00

In stock

North America, Western United States, South Dakota, Hell Creek Formation, Late Cretaceous period, ca. 68.5 to 66 million years ago. A fossilized theropod tooth attributed to Nanotyrannus, showing faint traces of serration along the front and back edges, features that helped slice through flesh. First described in 1942 and reclassified in 1988, Nanotyrannus remains a debated genus, with many paleontologists suggesting these teeth may represent a juvenile Tyrannosaurus rex rather than a separate species. The narrow, blade-like form is consistent with a lighter, more agile predator, adapted for cutting into prey. Size: 1.5″ L x 0.5″ W (3.8 cm x 1.3 cm)

Condition: Repaired from many pieces, with chips and losses. Infill along gaps and breaklines. Coated in a clear stabilizer and stable condition.

Provenance: private Rogers, Arkansas, USA collection; ex-Bosio collection, Miami, Florida, USA, 1960-2000
