Description
Insular dwarfism, a condition which renders large animals to either evolve or have smaller bodies due to the size of the environment and limited food source, can be seen throughout certain animals in the kingdom. Such can be seen with the Channel Islands Mammoth which stands around 1.72 meters tall and weighing between 750 to 800 kilograms, in stark contrast with its gargantuan mainland ancestors which stands around 4 meters tall and weighing around 9000 kilograms. In the world of Hypoemtasia, this condition also applies to animal groups or populations that were isolated from where their ancestors originated from for either more than or less than 10,000 years, with one of the few notable example being the Lemuriatitan, the only Lemurian titanosaur.
Reaching around a length of between 8 to 10 meters long and weighing between 4 to 8 tonnes, the Lemuriatitan is one of the smaller sauropods in the world of Hypoemtasia, alongside with the Forest Lumber, Afromokele and Sinomokele. Unlike their gargantuan Afrotasian cousin, the Afrobrachiotitan, they have a smaller build due to the size of the island, which limits the size of edible resources available to the titanosaurs, thus resulting in the immense size difference between the two genus in the same family. Like all sauropods, the Lemuriatitan possesses a long neck, 4 pillar-like limbs, and a tail in which they used for self defense. Despite having only the Lemuriavenator as their sole natural predator, they still have the trademark long neck that most sauropods possessed which they used to survey their surroundings and reach for the leaves on high-hanging foliage which only the lemurs can reach. All male Lemuriatitan possess a row of spikes which start from the end of their neck and ends at the mid-section of their tails. Males have a band at the base of their tail whereas females lack this band, demonstrating a minor difference of sexual dimorphism. They will achieve sexual maturity around the age of 10 and can live up to 60 years.
Solitary animals, the sauropods rarely socialize with other members of their kind throughout the entire year, unlike the other herbivores on the island that do so. When a Lemuriatitan desires to have a company, he will emit low-frequency rumbles that can be heard up to 3 kilometers. Any female that got hooked by the male's rumble will respond by returning a rumble of a higher frequency to signal the male that she is interested in him. If there are other male Lemuriatitan that could hear the rumble, they will respond by returning the same low-frequency rumbles, signifying that he is eager to have a duel with the one that emits the first rumble. Males will engage by leveling small areas of vegetation using their four pillar-like limbs accompanied by the rumbling bellows they created to impress the female sauropod. Naturally, the female will select the one that makes the loudest noise and the most destruction and copulate with him. Viviparous creatures unlike most of the Hypoemtasian sauropods, they will usually give birth between one to two live youngs at one time. Such a major change in its physiology is a direct response to the constrainment of living on an island and fewer resources, thus helping to keep the sauropod population in check and maintaining the general well-being of the island's ecosystem.
Being the sole sauropod on the island of Lemuria, the Lemuriatitans are a keystone species and they play an important role in shaping and maintaining the landscape of Lemuria. Foraging on soft leaves and sometimes even fruits, they inadvertently help to disperse the seeds of certain fruits across the island via droppings, which contains undigested waste that will eventually become fertilizers for the seeds, allowing the seeds to grow into trees, maintaining the landscape and the ecosystem of the island. Occasionally, the lemurs will hitch a free ride on the back of the titanosaur, transporting them from one feeding ground to another feeding ground. Being the largest of all the native species on the island, other smaller herbivores like the Armocollornis* ( A genus of aepyornithid with tough scales running across its short thick neck) and the lemurs will feed alonside with the Lemurian titanosaur, indirectly utilizing the presence of the titanosaur as a form of protection from predators like the Lemuriavenator and the Fossasuchus* (a 1-meter-long Arbrosuchus-like cursorial Mahajangasuchid).

Inspired by the dwarf titanosaurs from Dougal Dixon's The New Dinosaurs and the Amali, a Gabonese cryptid; based on the Rapetosaurus and CisioPurple's depiction of the Magyarosaurus.
Finally, another smaller sauropod for my Hypoemtasia Bestiary series! I might be making some more midget sauropods soon for this fictional world of mine!
The Possasuchus was inspired by the fossa and Kazanlak10's Agilisuchus; whereas the Armocollornis was inspired by TrollMans's Mammoth Bird.
I will be featuring both animals in my Hypoemtasia Bestiary series, tho I am not sure about the exact date they are going to be debuted
More GUUD stuff to come soon!
