Product details
Aerosteon riocoloradensis is a theropod dinosaur from the Late Cretaceous (approx. 84 million years ago), belonging to the Megaraptora clade, described from fossil remains found in the Anacleto Formation, in Argentine Patagonia. Its name, meaning "air bones," refers to a distinctive anatomical feature: the presence of extensive pneumatic cavities in the bones, associated with an advanced respiratory system comparable to that of modern birds.
From a biometric perspective, Aerosteon riocoloradensis reached estimated lengths of between 8 and 10 meters, with an approximate body mass of 1 to 2 tons. It had an elongated and relatively slender body, with well-developed hind limbs suggesting agile locomotion. The forelimbs were robust and equipped with large curved claws, typical of megaraptorans, possibly used for catching and holding prey. The skull, although incomplete in the fossil record, indicates a relatively light head. One of the most notable features is the presence of pneumatics not only in vertebrae and ribs, but also in elements such as the furcula and the abdominal region, suggesting the existence of air sacs similar to those of birds, implying a highly efficient respiratory system.
Regarding its habits, Aerosteon riocoloradensis was an active predator of high or medium-high trophic level, probably specialized in hunting medium-sized vertebrates. Its combination of speed, powerful claws, and an efficient respiratory system would have allowed for a relatively high metabolism, favoring dynamic hunting strategies. Although no direct integument impressions are preserved, due to its phylogenetic position it is plausible that it had some type of filamentous covering (proto-feathers), at least in certain body regions. Its dentition, although poorly known, suggests adaptation to cutting meat rather than crushing.
The habitat of A. riocoloradensis corresponded to continental ecosystems of Patagonia during the Late Cretaceous, characterized by alluvial plains, river systems, and semi-arid areas with dispersed vegetation. The Anacleto Formation documents a diverse fauna that included titanosaur sauropods, other theropods, and various terrestrial vertebrates. In this environment, Aerosteon occupied the role of a cursorial predator, interacting with multiple levels of the food web and contributing to the ecological dynamics of these Gondwanan systems.

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.
