Earlier this month (July 13th, 2021), Everything Dinosaur announced that PNSO were adding a replica of the controversial Late Cretaceous tyrannosaur Nanotyrannus to their product range. Logan the Nanotyrannus will join several other tyrannosauroid figures in the exciting and highly respected PNSO mid-size, prehistoric animal model range. A Tarbosaurus figure has been announced (Chaunzi the Tarbosaurus) and earlier this year, Everything Dinosaur announced that this range would also include a replica of Yutyrannus huali (Yinqi the Yutyrannus).

A Controversial Tyrannosaur Genus

Nanotyrannus (N. lancensis) was named and scientifically described in 1988 (Bakker et al), based on a slender skull (CMNH 7541) discovered by David Dunkle from the Cleveland Museum of Natural History (Ohio) in 1942. Bakker et al concluded that the skull represented an adult animal, but this has been refuted by a number of authors since publication. Other T. rex fossil finds, most notably the teenage specimen known as “Jane” excavated by palaeontologists from the Burpee Museum of Natural History (Illinois) and now part of a permanent tyrannosaur display, have demonstrated that the body shape of T. rex changed dramatically as it grew.

The narrow-skulled, long-limbed and more gracile tyrannosaur specimens probably do not represent a pygmy form of tyrannosaur that shared the Late Cretaceous habitat with the bruiser T. rex, these specimens are juveniles. However, as part of Everything Dinosaur’s commitment to education, we still have to prepare a fact sheet on Nanotyrannus to accompany sales of the PNSO Logan the Nanotyrannus dinosaur model.

Nanotyrannus Scale Drawing

Logan the Nanotyrannus could represent N. lancensis or perhaps it could represent a teenage T. rex. That decision ultimately rests with the purchaser, team members at Everything Dinosaur will be supplying their customers with a fact sheet and this will contain a scale drawing based on the original estimated size for Nanotyrannus of a little over five metres in length.
