Juvenile T. rex or Nanotyrannus?

These models were designed in March 2024. At that time, the acceptance of the Nanotyrannus species was under debate, and scientists leaned more toward the idea that the fossils they had were the remains of juvenile Tyrannosaurus rex, not adult Nanotyrannus.

In October 2025, the debate reached a surprising conclusion. After an investigation, it was determined that the fossils were definitely from adult Nanotyrannus individuals. That is why our current stock consists of juvenile Tyrannosaurus rex.

If you purchase now, the packaging, instructions, illustrated booklet, and model bases will say “Tyrannosaurus rex.” However, once this stock is depleted, we will modify the information in the booklet and replace the name on the packaging, instructions, and bases.

All customers who have purchased juvenile T. rex specimens can choose to receive the new bases and brochure completely free of charge, if they wish. These will be included in their next order, or they will only have to pay the shipping cost.

Nanotyrannus was a theropod dinosaur of the Tyrannosaurus family, the same family as the imposing T. rex. Just mentioning the word “Tyrannosaurus” conjures up images of enormous predators, but the modest Nanotyrannus also belongs to this family of giants.

On the other hand, the Tyrannosaurus rex is among the best known and studied dinosaurs. When we think of T. rex, this enormous predator comes to mind, but this leviathan did not always have those dimensions, at some point in its life it was a tender and playful dinosaur.

The T. rex juvenile siblings models at a 1:20 scale are an excellent reference point to learn about this species, its anatomy and the changes it undergoes during its growth. The pose of each one reflects a different personality and when you see them you will be able to recognize each one as separate individuals.

Their skulls can move freely at any angle from left to right from the base and their tails are divided into several points so you can curve them to give them a more organic and realistic appearance. Additionally, you can swap the skulls between them and place them on the body you prefer..

You can even place the juvenile T. rex models next to the Tyrannosaurus rex DELUXE model that represents the adult and you can appreciate how fascinating the changes in physiognomy and dimensions are between both stages of life.

This models are a must-have in the paleofauna collection and in that home museum that delights and educates anyone who observes it.

If you are interested in this model, please keep in mind that we designed it at a 1:20 scale, maintaining its real proportions. Therefore, the parts of these models can be fragile and delicate.
