A restoration of Rinconsaurus compared to a human ,

•  Based proportionally on fossil elements and skeletal reconstruction featured in the Rinconsaurus description,[1] with missing parts based on other titanosaur reconstructions. The remains of Rinconsaurus represent two adults and a juvenile all of which are incomplete; some of the proportions shown here, such as the neck, limb lengths, and skull shape are not certain.
•  Osteroderms are not yet known in Rinconsaurus.  The osteoderms shown here are based loosely on Mendozasaurus.[2] Osteoderms are known from at least 10 titanosaur genera spread across the family tree but it's not clear if all titanosaurs had them.[3] Titanosaur osteoderms are rare and their layout and position on the body are not certain. [4]
•  The colours and patterns, as with the majority of reconstructions of prehistoric creatures, are speculative.
•  Human silhouette approximately 180 cm tall.

NOTE: I often update my images. If you want to have any of my images on a website, please (if possible) don’t host/save it to the website server. I’d prefer it if the image's Wikimedia URL is used. This means that if I update an image, it will be updated on the site as well.  Thanks.

A new species of large tyrannosaur has been named and described from fossils found in Alberta (Canada). The new theropod, Tromerosaurus solumons, lived around 76 million years ago (Campanian faunal stage of the Late Cretaceous). Intriguingly, this predator possessed a mixture of anatomical characteristics associated with two major tyrannosaurid lineages. The study could change our
