Linhenykus was a tiny theropod dinosaur that lived around 83.6 million years ago during the Late Cretaceous period in what is now Inner Mongolia, China. Despite being one of the smallest known dinosaurs, measuring just 50 centimetres in length and weighing about 500 grams, this diminutive creature was remarkably well-adapted to its specialised lifestyle.
The most extraordinary feature of Linhenykus was its single-clawed forelimb - a unique characteristic that made it the first known dinosaur with only one functional finger on each hand. This powerful claw was likely used for breaking into termite mounds and ant colonies, making Linhenykus an ancient insectivore. Its long, slender legs suggest it was built for speed, enabling it to dart quickly across the landscape in search of its next meal.
As a theropod, Linhenykus belonged to the same group as fearsome predators like Tyrannosaurus rex, yet it evolved along a completely different path. Its skull was elongated with tiny teeth, perfectly suited for snapping up small insects rather than tearing flesh. The discovery of Linhenykus has provided valuable insights into how some theropods evolved to fill ecological niches similar to modern anteaters.
Living in a warm, semi-arid environment dotted with rivers and lakes, Linhenykus shared its world with various other dinosaurs, including larger theropods and herbivorous species. Its small size and specialised diet likely helped it avoid competition with larger predators whilst exploiting an abundant food source that few other dinosaurs could access.
What made Linhenykus distinctive?
Linhenykus had a single large claw on each forelimb, making it unique among dinosaurs. It possessed an elongated skull with tiny teeth, long slender legs for running, and was covered in primitive feathers or filaments.
Behaviour
Linhenykus likely used its powerful single claw to break open termite mounds and ant colonies, similar to modern anteaters. Its long legs suggest it was a fast runner, probably darting quickly between feeding sites and using speed to escape from larger predators.
Discovery
Linhenykus was first described by Xu Xing and colleagues in 2011. The original fossils were discovered at Wulansuhai Formation, Inner Mongolia, China.
Linhenykus FAQ
What did Linhenykus eat?
Linhenykus was a carnivore that specialised in eating insects, particularly ants and termites. Its single powerful claw was perfectly adapted for breaking into insect colonies, whilst its small teeth were ideal for catching and eating tiny prey.
How big was Linhenykus?
Linhenykus was tiny for a dinosaur, measuring just 50 centimetres long and standing about 20 centimetres tall at the hip. It weighed approximately 500 grams, making it lighter than most domestic cats and one of the smallest known dinosaurs.
When did Linhenykus live?
Linhenykus lived during the
Late Cretaceous period, approximately 83.6 million years ago. This was towards the end of the age of dinosaurs, about 17 million years before the mass extinction event that ended the Mesozoic Era.
Where was Linhenykus found?
Linhenykus fossils were discovered in Inner Mongolia, China, specifically in the Wulansuhai Formation. This region was once a warm, semi-arid environment with rivers and lakes during the
Late Cretaceous period.
How do you pronounce Linhenykus?
Linhenykus is pronounced 'LIN-hen-EYE-kus'. The name comes from Linhe, a city near where the fossil was found, combined with the Greek word 'onyx' meaning claw, referring to its distinctive single-clawed hands.
What does Linhenykus mean?
The name Linhenykus means 'Linhe Claw', combining 'Linhe' (a city in Inner Mongolia near the discovery site) with the Greek word for claw, highlighting its most distinctive feature - the single large claw on each hand.
How fast could Linhenykus run?
The exact speed of Linhenykus is unknown, but its long, slender leg bones suggest it was built for running. Given its small size and need to escape predators, it was likely quite swift relative to its body size.
What type of dinosaur was Linhenykus?
Linhenykus was a theropod dinosaur, belonging to the family Alvarezsauridae. Despite being in the same group as famous predators like T. rex, it evolved to become a tiny insect-eater rather than a large carnivore.
Was Linhenykus related to birds?
Yes, as a theropod dinosaur, Linhenykus was closely related to birds. All modern birds evolved from theropod dinosaurs, and Linhenykus likely had primitive feathers or feather-like structures covering its body.
How many Linhenykus fossils have been found?
Linhenykus is known from a single, nearly complete skeleton discovered in 2008 and described in 2011. While only one specimen has been found, it was well-preserved enough to reveal most of the animal's anatomy and unique characteristics.
