Product description and measurements
Irritator challengeri is a genus of spinosaurid theropod dinosaur that lived during the Early Cretaceous Period, approximately 110 million years ago, in what is now Brazil. Its name comes from the Latin "irritator", in reference to the frustration of paleontologists upon discovering that the original fossil had been altered with plaster by the collectors who found it, and "challengeri" in honor of Professor Challenger, a fictional character created by Arthur Conan Doyle.

Irritator is best known for a well-preserved partial skull recovered from the Santana Formation, famous for its exceptionally preserved fossils. This theropod is classified within the spinosaurids, a group of carnivorous dinosaurs with adaptations to a semi-aquatic lifestyle. Its elongated and narrow skull, similar to that of modern crocodiles, had conical, unserrated teeth, ideal for catching fish. This morphology suggests that Irritator was piscivorous, although it may also have hunted small terrestrial prey.

Recent research highlights that the skull of Irritator had an advanced sensory system in the snout, with neurovascular canals that would have allowed it to detect movements in the water, similar to what is seen in modern crocodiles. In addition, biomechanical studies suggest that its bite was adapted to hold slippery prey, rather than exerting extreme force like other theropods.

Irritator probably had a slender body and long limbs, adaptations that are associated with both terrestrial and aquatic locomotion. Although complete remains of its skeleton have not been found, comparisons with other spinosaurids indicate that it could have reached a length of 7 to 8 meters. It probably had a low dorsal sail formed by extensions of the vertebrae, similar to that of other members of its family.

This dinosaur inhabited a warm coastal environment, with lagoons, rivers, and mangrove areas that offered an abundance of fish and other resources. Its semi-aquatic ecological niche placed it in a unique role within the ecosystem, sharing its habitat with other marine reptiles and terrestrial dinosaurs.

Recent studies on Irritator have enriched our understanding of spinosaurids as a diverse and ecologically versatile group of dinosaurs. These findings underscore the importance of South American fossils in deciphering the evolutionary history of semi-aquatic dinosaurs.

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.
