Described in a study published in\u00a0Biology Letters<\/em><\/a>, the discovery of Benggwigwishingasuchus eremicarminis<\/em> (B. eremicarminis<\/em>) reveals that while giant ichthyosaurs<\/a> ruled the world’s oceans during the Middle Triassic (247.2 to 237 million years ago), it was ancient pseudosuchian archosaurs that dominated the shores.<\/p> The find rewrites the story of life along the world’s coasts during the first act of the Age of Dinosaurs, says lead author of the paper Dr. Nate Smith, Curator of the Dinosaur Institute at the Natural History Museum of Los Angeles County<\/a> (NHMLAC).<\/p> Despite its mountainous character today, the Favret Formation in central Nevada, USA, once lay beneath the eastern Panthalassan Ocean, an ancient superocean that surrounded the supercontinent Pangaea. Indeed, the area is known for fossils of sea-dwelling creatures such as ammonites and marine reptiles including giant ichthyosaurs. Finding the newly described\u00a0B. eremicarminis<\/em>\u00a0came as a bit of a shock to the researchers.<\/p> \u201cOur first reaction was: What the hell is this?\u201d said co-author Dr. Nicole Klein, who was expecting to find marine reptiles. Instead, it was the partially articulated skeleton of B. eremicarminis<\/em> that the scientists uncovered. The remains, which consist of parts of the skull as well as most of the spinal collumn, girdles and limbs, suggest the animal was probably around 1.5m in length.<\/p> “We couldn\u2019t understand how a terrestrial animal could end up so far out in the sea among the ichthyosaurs and ammonites. It wasn\u2019t until seeing the nearly completely prepared specimen in person that I was convinced it really was a terrestrial animal.\u201d\u00a0<\/p> Together with other pseudosuchians from the Tethys Ocean (now the Indian Ocean, Mediterranean Sea and the Eurasian inland marine basins), B. eremicarminis<\/em><\/em>\u00a0reveals that during the Middle Triassic these crocodile kin were also occupying parts of the Panthalassan Ocean and the Western Hemisphere, and thus coastal marine habitats around the world.<\/p> Interestingly, the study explains that these coastal species aren\u2019t all from the same evolutionary group, suggesting that pseudosuchians (and archosaurs more widely) were independently adapting to life along Earth’s shores.<\/p> \u201cEssentially, it looks like you had a bunch of very different archosauriform groups deciding to dip their toes in the water during the Middle Triassic. What\u2019s interesting, is that it doesn\u2019t look like many of these \u2018independent experiments\u2019 led to broader radiations of semi-aquatic groups,\u201d explains Smith.<\/p> \u201cA growing number of recent discoveries of Middle Triassic pseudosuchians are hinting that an underappreciated amount of morphological and ecological diversity and experimentation was happening early in the group\u2019s history. While a lot of the public\u2019s fascination with the Triassic focuses on the origin of dinosaurs, it\u2019s really the pseudosuchians that were doing interesting things at the beginning of the Mesozoic.”<\/p> “While a lot of the public\u2019s fascination with the Triassic focuses on the origin of dinosaurs, it\u2019s really the pseudosuchians that were doing interesting things.”<\/p><\/blockquote> The new species Benggwigwishingasuchus eremicarminis<\/em> translates broadly as ‘fisherman croc\u2019s desert song’. The first half of the name Benggwigwishingasuchus<\/em> is a combination of the word ‘Benggwi-Gwishinga’, meaning ‘catching fish’ in Shoshone, the language of the Augusta Mountains’ Fallon Paiute Shoshone Tribe, and the Greek word for Sobek, the Egyptian crocodile-headed god. While eremicarminis<\/em>\u00a0translates to ‘desert song’, paying homage to two supporters of NHMLAC who have a passion for palaeontology and opera.<\/p> The new species underlines the great number of these ancient reptiles during the Triassic, from huge animals such as\u00a0Mambawakale ruhuhu<\/em>\u00a0to smaller animals such as the newly described\u00a0B. eremicarminis<\/em>.<\/p> Because only a few parts of the\u00a0B. eremicarminis<\/em>\u00a0specimen were found, clues to how it fed and hunted are few and far between. However, the researchers say that the well-developed limbs, which have no signs of aquatic living, such as flippers or altered bone density, suggest that\u00a0B. eremicarminis<\/em>\u00a0likely stuck close to the shore.<\/p> Find out more about the study: A new pseudosuchian from the Favret Formation of Nevada reveals that archosauriforms occupied coastal regions globally during the Middle Triassic<\/a><\/em>.<\/p> Main image: Benggwigwishingasuchus eremicarminis on the Panthalassan Ocean coast.
