MAIN INFORMATION: Titanosaur indet. is an unconfirmed genus and species of Titanosaurs that lived in Nemegt Formation of Mongolia from 66 Million Years ago to 89 Million Years ago.

PHYSICAL APPEARANCE: Just like many other Titanosaurs, the Mongolian Titan would look like a quadruple mass-body Sauropod, having no physical displays or details, having a very long thick neck preferably stretching tall instead of straight, slightly narrow round snout, and a bald tail that slightly measures less than the length of its body. The Mongolian Titan would have short non-opposable spiked thumbs on both the rear and front set of their feet, just like other Titanosaurs.

APPEARANCE: Mongolian Titanosaur would mainly have colors like the desert, having a ochre color of light brown all across its head, neck, body and neck. But the upper "roof" half of its neck, body and head would be colored a more vibrant desert brown. This skin color applied to both male and female Titanosaurs, having no significant sexual Dimorphism whatsoever.

PALEONTOLOGY: Only known from footprints, the Mongolian Titan is stated on the show as possessing a mass of around 70 metric tons (77 short tons), it weighs almost as much as Argentinosaurus, which is consistently estimated to weigh around 75 - 80 metric tons, or 83 - 88 short tons. As of the time of its appearance, it was the biggest animal ever featured on Prehistoric Planet, only eventually surpassed by Alamosaurus in North America, which brings up its maximum weight estimate of 80 metric tons (88 short tons).

The Mongolian Titan's sole evidence of existence are sauropod tracks labeled as "Brontopodus" (Thunder Foot), not to be confused for the identically-named footprints of a Late Jurassic diplodocid that lived in North America (likely Dyslocosaurus). These tracks are believed to come from an animal that exceeds the size of any creature known from the Nemegt Formation, including the area's two known titanosaurs, Nemegtosaurus and Opisthocoelicaudia, which has a foot that resembles the FS40 "Brontopodus" track.

The Mongolian Titan lived 70 million years ago in the Nemegt Formation, an area that would one day become the Gobi Desert in Mongolia. The formation shows evidence of a rich, humid environment with large river channels, tidal flats, and forests. However, the area is also known to have undergone periodic droughts, and there is precedence for arid regions much like the Gobi Desert today existing in Mongolia during those times, thus justifying the depiction of Mongolian Titan living in or at least traveling through a vast desert environment, with a color scheme of earthly tones fit for desert-dwelling animals.

SETTINGS: This would take place in a Mongolian desert full of dunes but some canyons, located in the Nemegt Formation.

SIZE: The body to tail length of Mongolian Titan would range over 17 meters on average. Not only would that make Mongolian Titan large as it is, Mongolian Titan would be over 42 meters tall and weighing over 176300 pounds, making it one of the largest Sauropods or Land animals ever to live once confirmed to exist.

Dating in the Maastrichtian Cretaceous Era, 70 Million Years ago in the same place prior to becoming the Gobi Desert of Mongolia, would lie a vast endless sandy desert of Nemegt Formation. There were only a few vegetation of shrubs around the deserts, those shrubs being mostly seen and available in trenches of canyons. There was atleast large bodies of waters that were distanced far away from each other in the deserts, and water was what mostly mattered to the dinosaurs.

Despite this setbacks in Nemegt Formation, dinosaurs did thrive here to become the largest, especially herbivores. Herbivores such as the Nemegtosaurus and Erketu were the very few Sauropods that evolved to be relatively large in size here in Nemegt Formation... But there would be another Sauropod, a Titanosaur, and even larger than the previous Mongolian Sauropods named.

That would be the Mongolian Titanosaur.

Due to the lack of evidence and only footprints of them, Mongolian Titanosaurs were vaguely named, also known as "Titanosaur indet." unfortunately. But once confirmed, the Mongolian Titanosaur would be one of the largest - not only Sauropods, but land animals to ever live on the planet earth. A herd of over 24 of these Mongolian Titans, all of them no young but adults that stood at 42 meters tall and a staggering weight of 176300 pounds on average, would be marching down the dunes of the desert close to the walls of a canyon that was over 50% bigger than them. Being heavy, these Titanosaurs were only able to walk at 4 miles per hour, but were very unlikely to be killed at the age of adults. The herd would be migrating, but with a large maze of canyons to walk into that was the hardest the herd had to go through.

As the herd of 22 adults of Mongolian Titanosaurs started to enter into this large spanning trenches of the canyons, they started to get nervous. Despite their humongous stature, the geographical features of these canyons could kill them. There were many unpredictable floors that the Mongolian Titanosaurs were to tall to see beyond them, either going high or getting deep, as of previous experiences even the largest of the herd could die from fall damage. The herd slowly trudged down into the canyon, all following each other through the curved walls and straight trenches the canyon had for them, hoping they were able to exit this canyon at such a slow rate for a long maze.
