All about dinosaurs, fossils and prehistoric animals by The whole lot Dinosaur crew members.
The whole lot Dinosaur has not too long ago printed a brief video reviewing the PNSO Aymen the Spinosaurus dinosaur mannequin. The video additionally summarised current analysis into this outstanding theropod. In September 2014, researchers printed an influential paper that postulated that Spinosaurus was an obligate quadruped. That’s, in contrast to all the opposite theropods recognized to science, Spinosaurus was not a biped. It walked on all fours.
Mannequin makers had been eager to develop Spinosaurus aegyptiacus figures that mirrored this analysis.

Ten Years of Spinosaurus Analysis
Spinosaurus aegyptiacus has been the main target of intense analysis over the past ten years. Its mode of locomotion, weight loss program and behavior have come beneath detailed scrutiny. Palaeontologists stay unsure as as to if this dinosaur was an aquatic animal. The 2014 paper (Ibrahim et al) postulated that Spinosaurus was semiaquatic. It spent a substantial period of time in or round water. Earlier analysis had demonstrated that Spinosaurus was most likely a piscivore. What quantity of its weight loss program comprised fish stays unknown.
Given the massive variety of super-sized predators inside the palaeoenvironment, it has been advised that Spinosaurus grew to become specialised with a view to keep away from competitors. This can be a type of area of interest partitioning.
The The whole lot Dinosaur video evaluation of the PNSO Aymen the Spinosaurus determine summarises a few of this current analysis.

The reconstruction of Spinosaurus aegyptiacus as a quadruped attracted criticism. Some scientists commented upon the dearth of extra full fossil specimens representing particular person animals. The researchers led by Nizar Ibrahim reconstructed Spinosaurus utilizing a number of completely different fossil specimens. The scaling of a number of the bones used within the reconstruction precipitated concern.

Tracing Spinosaurus Analysis with PNSO Figures
Spinosaurus figures have been a part of the PNSO mannequin vary for a few years. A 1/thirty fifth scale Scientific Artwork determine (beneath) was an early addition to the corporate’s dinosaur portfolio. This dinosaur determine was known as “Essien”. A mannequin of a child Spinosaurus was additionally included within the firm’s prehistoric animal mannequin collection.
The PNSO Spinosaurus measures round 49 cm lengthy.
A second “Essien” the Spinosaurus mannequin was launched by PNSO in 2020. In 2022, the 1:35 scale mannequin was revamped and relaunched in a brand new color scheme. It nonetheless depicted Spinosaurus as an obligate theropod. Altering perceptions about this dinosaur could be traced by the evolution of PNSO Spinosaurus figures.
PNSO Aymen the Spinosaurus
This yr (2024), a brand new Spinosaurus mannequin has been launched by PNSO. The PNSO Aymen the Spinosaurus determine displays a number of the newest scientific pondering. It has a broad tail as demonstrated in a scientific paper printed in 2020 (Ibrahim et al). It’s offered as a bipedal dinosaur (strolling on its hind legs).
A spokesperson from The whole lot Dinosaur said:
“Spinosaurus is prone to intrigue palaeontologists for a few years. The absence of an articulated and extra full fossil specimen representing a person animal is hampering analysis. The brand new PNSO Aymen the Spinosaurus broadly displays the present scientific pondering. That’s, till the subsequent Spinosaurus aegyptiacus fossil discover.”

Mockingly, the day The whole lot Dinosaur obtained a PNSO supply, a brand new paper was printed that challenged the findings of earlier analysis. Potential measurement errors had been highlighted in a research initially printed in 2022 that concluded that Spinosaurus had dense bones to assist it dive and submerge. As crew members had been unloading the lorry, information of the publication of the newest Spinosaurus paper broke.
