‘Amazing’ goose-necked dinosaur was built like a diving chicken
The expansive dinosaur group that involved big predators this kind of as T. rex also was populated by a variety of oddballs, weirdos and outcasts. A recently described dinosaur from Mongolia – the dimensions of a goose and looking a bit like just one, much too – fits that description.
The dinosaur, named Natovenator polydontus, lived about 72 million many years ago during the Cretaceous Time period and was constructed like a diving chicken with a streamlined entire body while possessing a goose-like elongated neck and a prolonged flattened snout with a mouth bearing extra than 100 small enamel, scientists mentioned on Thursday. It just about certainly was coated in feathers, they additional.
“Natovenator has a lot of peculiar features,” explained paleontologist Yuong-Nam Lee of Seoul Nationwide College in South Korea, lead creator of the research revealed in the journal Communications Biology.
While it was a cousin of speedy very little predator Velociraptor, Natovenator was tailored to a semi-aquatic life-style in a freshwater ecosystem, possibly floating on rivers and lakes, paddling with its front limbs, and making use of its flexible neck to catch fish and bugs or diving underwater to capture its prey, the scientists explained.
Its properly-preserved remains – a skeleton about 70% complete – were unearthed in the Gobi Desert, which in excess of the a long time has been a treasure trove for dinosaur fossils.
Natovenator is element of the dinosaur team identified as theropods – sharing characteristics like bipedalism – best regarded for massive meat-eaters which include Tyrannosaurus, Tarbosaurus and Giganotosaurus. But the theropods, many of which were feathered, branched out in uncommon instructions with illustrations this kind of as extensive-clawed floor sloth-like Therizinosaurus, ostrich-like Struthiomimus, termite-eating Mononykus and the full fowl lineage.
“The range of theropod dinosaurs by the close of the Cretaceous is fully wonderful,” said University of Alberta paleontologist and study co-author Philip Currie.
“I feel there will be extra discoveries of intriguing, strange theropods in the future,” Lee additional.
Not numerous of the dinosaurs termed “non-avian” – in other words, not the birds – are known to have lived a semi-aquatic lifestyle. A close relative of Natovenator named Halszkaraptor, explained in 2017, lived a comparable life-style at approximately the exact same time in the very same region. Both had a very chicken-like physical appearance and had been carefully linked to the chicken lineage.
Natovenator calculated about 18 inches (45 cm) lengthy, with a cranium about 3 inches (7 cm) prolonged. Its front limbs appeared somewhat flattened, maybe as an adaptation for paddling and swimming. The streamlining of its physique is revealed by ribs that position towards the tail, as in diving birds, an arrangement that lowers drag in the water and permits effective swimming.
“Natovenator – which usually means ‘swimming thief’ – is an wonderful minimal animal for a number of reasons. Very first it is compact and fragile. When we identified it, we ended up unsure as to its identification for the reason that it looked additional like a lizard or mammal skeleton than a dinosaur. The moment it was geared up, we realized it was a theropod dinosaur, but what sort? At last it built perception after Halszkaraptor was explained,” Currie explained.
“It is extremely specialized for living in an atmosphere not standard for an animal associated to Velociraptor and its other kinfolk. Most individuals believe of dinosaurs as specialised land animals, not competing with crocodiles in the h2o,” Currie extra.
There ended up various diving birds through the Cretaceous, including North America’s Hesperornis, which attained about 6 ft (1.8 meters) extensive, but none are recognised from the place Natovenator inhabited.
“More than 30 unique lineages of tetrapods (terrestrial vertebrates) have independently invaded drinking water ecosystems,” Lee claimed. “Why not dinosaurs?”
