Product description and measurements

Nanotyrannus lancensis is a controversial tyrannosaurid theropod taxon from the Late Cretaceous (Late Maastrichtian), known primarily from a relatively complete skull (CMNH 7541) found in the Hell Creek Formation of Montana, USA. Its validity as a separate genus has been widely debated, with numerous studies interpreting it as a juvenile Tyrannosaurus rex , while others maintain that it possesses its own diagnostic features.

The type specimen is a relatively large individual, though smaller than adult tyrannosaurs, with an estimated body length of 5–6 meters and a mass of approximately 600–1,000 kg, depending on the allometric model used. Its overall build was gracile compared to Tyrannosaurus rex , with relatively long and slender hind limbs, suggesting greater cursorial capability.

The skull is proportionally elongated and narrow, reaching approximately 60 cm in length. It has large, subcircular orbits, a typical feature of juvenile individuals in many archosaurs. The antorbital fenestra is well developed, and the rostral region is more laterally compressed than in adult specimens of robust tyrannosaurids. One of the arguments in favor of its taxonomic validity has been the high number of maxillary teeth (around 17 per side), higher than the usual number in adult T. rex , which typically has 11–12; however, it has been noted that the tooth count can vary ontogenetically.

The dentition shows laterally compressed, recurved teeth with finely serrated keels, adapted for efficient tissue cutting. Unlike large adult tyrannosaurids, whose premaxillary teeth have a marked "D" cross-section, in the specimen attributed to Nanotyrannus these proportions are less robust, reinforcing the hypothesis of a juvenile morphology or a more slender morphotype.

The postcranial skeleton, based on referenced materials and controversial assignments, suggests a bipedal animal with a long, proximally rigid tail to balance the trunk during locomotion. The forelimbs, typically reduced in tyrannosaurids, retained the functional morphology of two main digits with robust claws. The hindlimbs show relatively long tibiae relative to the femur, a ratio associated with greater relative speed compared to the massive adults of Tyrannosaurus .

Histologically, some bone growth analyses have indicated that certain specimens attributed to Nanotyrannus exhibit bone tissue still in an active growth phase, supporting the hypothesis that they are juvenile Tyrannosaurus rex individuals. However, the discussion continues within the systematics field, as the distinction between ontogenetic variation and actual taxonomic differences in tyrannosaurids is complex.

Information about aftershocks

Collector's item ; Hyper-realistic replica, highly detailed and with a high degree of scientific precision.

Made to scale, prototyped in resin and with a scenic base in most of the models offered. If you like miniatures, both for collecting and for painting, we offer you a wide variety of scale replicas; All of them related to dinosaurs, extinct prehistoric fauna and current fauna.

So if you love dinosaurs and animals as much as we do, this is your favorite store to collect and paint them :)

We are authorized distributors of all the replicas and figures we offer. We use 3D printers with 8K - 14K resolution, and high-quality resins with additives to improve hardness and flexibility, thus offering replicas of impeccable quality.

Different scales will be used to make the replicas (depending on the size of the species), although we are open to making other suggested scales upon request as long as they fit in our printing trays, for which you will have to contact us via email and request the required size.

Replicas are supplied with the option of airbrush priming in dark grey. If you require another colour, please let us know which one you prefer in the box with special instructions for the seller. Without priming, we do not guarantee that the resin will accept paint.
We also offer the option of choosing a professionally painted replica, which is agreed upon throughout its development with the painter, through a private chat available.

Complete replica (one piece): We supply complete replicas in those models that are small, and models that are medium, large or not very bulky, will have the prerogative of being presented as a complete replica or assembly kit as the case may be.
Complete replicas will be supplied separately from their base.

Replica assembly kit: We supply replicas whose models are large, very large or bulky, only with this option.
The indicated replicas (generally composed of base, head, body and tail) will come prepared for the subsequent assembly that will be required by the client, by sanding, putty, adhesive or technique chosen by the client.

All replicas are thoroughly inspected before shipping and will be carefully packaged to prevent damage during transport.

Information about the models

The poses of the models aim to represent each character in the most scientifically viable way, thus revealing the life and customs of prehistoric and modern fauna.

Each character has its own personality and develops in different life scenarios; birth, adolescence and play, hunting, feeding, fighting, courtship, death and many other scenes from their daily life, always from the creative perspective of their designers.

Handmade

All orders are individually prepared on the cutter for subsequent prototyping, obtaining a resin part that will require post-processing by manual and ultrasonic cleaning, support removal, ultraviolet curing, labeling and packaging.

We are authorized distributors

We offer both our own physical replicas and those that have been modeled by many of the best 3D designers, in order to offer you the greatest possible variety.
