It more argued that the orientation of your semicircular canals varies appreciably inside of modern-day species, and is consequently not trusted for determining head posture.[23] This was supported with the Spanish palaeontologist Jesús Marugán-Lobón and colleagues in a 2013 examine that instructed the strategies employed by Sereno's team had been imprecise, Which Nigersaurus habitually held its head like other sauropods.[24]
Even with its scaled-down dimensions, Nigersaurus is noteworthy for its one of a kind adaptations, particularly its specialized teeth and feeding mechanisms, which distinguish it in paleontological research.
Nigersaurus, a rebbachisaurid sauropod from the middle Cretaceous interval, was learned in the Elrhaz Development in Niger.

If true, it might starkly distinction with most sauropod reconstructions, demonstrating the animal holding its head horizontally.
By having an astonishing 500 teeth, this dinosaur presents a unique glimpse to the evolutionary adaptations of prehistoric creatures. Enable’s discover the earth from the Nigersaurus and its interesting dental anatomy.
All our content are based upon the most useful sources and scientific functions. Posts also are determined by our very own analysis and paleontological excavations.
Nigersaurus's downward-experiencing mouth and vast dental arrangement recommend it grazed on ground-degree plants in lieu of searching significant vegetation.
Other researchers have disputed this assert, even though. Scientific tests introduced in 2009 and 2013 discovered which the posture of your LSC cannot reliably convey to us what any provided sauropod's standard head posture looked like. Anyone desires to construct a time equipment presently.
