Description

Full-scale reconstruction of the sparassodont Thylacosmilus atrox. Made in life-size in a hyper-realistic way with synthetic elements.

It can be made in full body and in any pose on request.

About this animal: Thylacosmilus had a body size similar to that of a current puma and was equipped with a pair of very long canines of about 15 centimeters that, in a resting position, were folded over one cheek. Thylacosmilus was a metatherian and had a pouch similar to current kangaroos.

Despite its resemblance to sabre-toothed tigers such as Smilodon or Barbufelis, it is more closely related to marsupials.

It belongs to the Sparassodonta and they were metatherians. Although it has often been considered a case of convergent evolution, with other “saber-toothed” predators, perhaps Thylacosmilus was a scavenger. Its jaws have teeth that are ineffective for predation, weak, with missing pieces and little muscle. It has a large space in the mouth that could be used to house a large tongue that would allow it to scrape up corpses. Its eyes are deeply sunken into the skull and directed to the sides, which could impair its three-dimensional vision.
