Its skeleton was highly pneumatised (filled with air spaces connected to air sacs), but the limbs were robustly built. A new genetic analysis, published in the journal Molecular Phylogenetics and Evolution, has now established which animal still living today is the closest relative of the Steller's sea cow. That and its slow-moving, almost docile behaviour made it easy prey. And even today, scientists are still discovering fundamental insights into the life and history of this huge, lumbering, but almost mystical animal. Literally Can’t Even.

Hunters may have killed seven times as many sea cows as they could eat. It had a wide muzzle filled with more than 500 teeth, which were replaced at a rapid rate: around every 14 days. [1] In 2007, a more detailed description of the skeleton was published by Sereno ad colleagues, based on a specimen discovered ten years earlier. The same article also named Jobaria, another sauropod from Niger. Its skull was very specialised for feeding, with large fenestrae and thin bones. However, his stature has saved him from becoming a burger.

Nigersaurus also bears signs of low-angle tooth-to-tooth wear on the inside of the maxillary crowns, which suggests that jaw movement was limited to precise up-and-down motions. It belonged to a different group of mammals, known as the Sirenia, named after the … Both this and the other mastication muscles were likely weak, and Nigersaurus is estimated to have had one of the weakest bites of the sauropods. [1], Like all sauropods, Nigersaurus was a quadruped with a small head, thick hind legs, and a prominent tail. In early 2018, parodies and jokes about the trend began appearing. The jaws also contained several fenestrae, including three that are not present in other sauropods. As a result, no other tetrapod had all of its teeth located as far to the front as Nigersaurus. [15], Though it had large nostrils and a fleshy snout, Sereno and colleagues found that Nigersaurus had an underdeveloped olfactory region of its brain and thus did not have an advanced sense of smell. This is unlike the way other sauropods have been restored, with their heads held more horizontally. [12] Pneumatisation of the rebbachisaurid skeleton evolved progressively, culminating in the nigersaurines. Remains thought to belong to Nigersaurus were first discovered during a 1965–72 expedition to the Republic of Niger led by French paleontologist Philippe Taquet, and first mentioned in a paper published in 1976. [18] This was supported by the Spanish palaeontologist Jesús Marugán-Lobón and colleagues in a 2013 study that suggested the methods used by Sereno's team were imprecise, and that Nigersaurus habitually held its head like other sauropods.
