21 Dino-mite Nothronychus Facts That Kids Will Love

There are so many fun Nothronychus facts to know and learn about! How many of these did you already know?

The Nothronychus is a relatively lesser-known herbivore recorded in the annals of pre-historic history for its immense size. Considered harmless for the most part, this creature towered over many other predators and herbivores in its time. Scientists also believe that herbivores like the Nothronychus may have had a role to play in the ecology of their habitat, simply because of their behemoth size and immense consumption of vegetation. It is also assumed that they were extremely difficult to hunt since their huge size often dwarfed even the biggest of predators. They are also known to be solitary animals, but there is still some research left to be conducted on this since there have been no group structures discovered for this species.

There are so many fun facts for you to know and learn about in the world of dinosaurs! With so many pre-historic friends to know and learn about, you can continue your search into the field of dinosaurs with others like the Prosaurolophus and Rahonavis. Do not forget to share with your friends, and read on to know everything about the Nothronychus!

Nothronychus Interesting Facts

How do you pronounce 'Nothronychus'?

The word Nothronychus is pronounced at 'Nof-ron-e-kus'.

What type of dinosaur was a Nothronychus?

Theropod dinosaurs of the therizinosaurid genus Nothronychus mckinleyi (meaning 'slothful claw') lived in North America during the Late Cretaceous period.

In which geological period did the Nothronychus roam the earth?

The species of North America, N mckinleyi, lived roughly 91 million years ago in the Southern United States during the Late Cretaceous Period. The type species, N mckinleyi, was identified by James Kirkland with Douglas G. Wolfe in 2001.

When did the Nothronychus become extinct?

On August 22, 2001, the New Mexico group led by paleontologists Doug Wolfe and Jim Kirkland announced their discovery in the Journal of Vertebrate Paleontology and named a very strange dinosaur. It is assumed that Nothronychus Therizinosauridae becomes extinct about 89 million years ago.

Where did a Nothronychus live?

Nothronychus with small head ate just plant (herbivore). It lived in North America during the Cretaceous period. Its fossils have been found in the Zuni Basin, which is located in Arizona And New Mexico.

A second specimen, Nothronychus graffami, was found in southern Utah and described in 2009 and dated to the early Turonian, approximately one million to half a million years older than Nothronychus mckinleyi.

What was a Nothronychus's habitat?

Nothronychus, the sloth-like dinosaurs, lived in tropical jungle habitats and likely ate a variety of plants. Feathers were presumably absent from its inner arms, breast, and lower neck.

Who did a Nothronychus live with?

Only one Victor Leshyk Nothronychus skeleton was discovered, indicating that these dinosaurs were usually solitary. Given their size and dietary needs, it would have been very difficult for them to live with similar specimens, simply because the ecology of the area would be destroyed.

How long did a Nothronychus live?

This dinosaur, name Nothronychus means 'sloth-like claw', survived from Cenomanian Age till 89.3 million years ago.

How did they reproduce?

This sloth-like species, N mckinleyi, was oviparous and reproduced by laying eggs.

Nothronychus Fun Facts

What did a Nothronychus look like?

Both dinosaurs, N.‭ ‬graffami, and N. mckinleyi were about the same size, measuring 14 ft (4.2 m) in length and about 1984.2 lb (900 kg) in weight. Nothronychus graffami of Utah, on the other hand, was marginally more vigorous than mckinleyi dinosaur. N mckinleyi was a ponderous dinosaur with a large 'pot-bellied' abdomen, leaf-shaped teeth, long neck, small head, and stocky hindlimbs. Although some possessed feathers, they remained close relatives of the dinosaurs that gave birth to the first birds. The long arms and agile hands have claws on their fingers up to 11.8 in (30 cm) long, curled, and highly pointed. Furthermore, the tail was made shorter yet more flexible. Feathers were presumably absent from its inner forearms, chest, and bottom neck.

Nothronychus were large plant-eating theropods, described by Douglas G. Wolfe and James Kirkland in 2001, with broad, sloth-like haunch (hip) four-toed feet with every four toes facing ahead, elongated thin neck and long arms with sharpened claws.

How many bones did a Nothronychus have?

For this therizinosaurs specimen, just one Nothronychus skeletal has been found so far. The fossil is also not complete, containing just pieces of the relatively scant skull, several vertebrae, and elements of the shoulder joint, hip, and hindlimbs, as well as a few other fossil parts. Because the full skeleton of these theropod dinosaurs, found in 2001, is unknown, it is hard to estimate how many bones they had.

How did they communicate?

Due to lack of research, it is unknown how these dinosaurs interacted with each other.

How big was a Nothronychus?

The average nothronychus size (wildlife) was between 14.5-19.5 ft (4.4-6 m). when we study Paleontology, we come across some interesting comparisons, such as the therizinosaurus vs. nothronychus size and the nothronychus vs. beipiosaurus.

How fast could a Nothronychus move?

The Nothronychus speed is relatively slow due to its large size, which was named in 2001, and its close early relatives possessed feathers.

How much did a Nothronychus weigh?

The average weight of this dinosaur having leaf-shaped teeth was approximately 2204.7 lb (1000 kg).

What were the male and female names of the species?

No specific title has been assigned to the male and female dinosaurs of this new Nothronychus (feathered) species, named after the land owner on which the specimen was discovered.

What would you call a baby Nothronychus?

The newborn dinosaurs of this new species (named in 2001), which have sharp nails on their fingers but no wings in the skeleton-like their feathered close relatives, have no name.

What did they eat?

The teeth of these large therizinosaurs dinosaurs were leaf-shaped like many other plant-eating dinosaurs. However, these theropods had a small head, long arms with a stocky tail, fingers with bent claws, lived in a tropical forest environment, and perhaps fed on different types of plants in their diet. The majority of this plant-eating animal's waking hours were spent plucking and ingesting massive amounts of leaves.

How aggressive were they?

These strange dinosaurs, whose genus name originates from Greek meaning 'slothful claw', ate plants largely in their diet and had feathery relatives, were not aggressive.

Did you know...

The type species name N. mckinleyi, named by Douglas G. Wolfe, and James Kirkland (2001), honors Bobby McKinley, the land-owner in which the Nothronychus dinosaur type fossil was found.

Nothronychus facts for kids: Graffami Theropods dinosaur was obtained from marine sediment of southern Utah.‭ ‬This indicates that this dinosaur was swept out to sea and eventually came to rest at the base of what was then regarded as the Western Interior Seaway.

How long were Nothronychus claws and what did they use it for?

This dinosaur's claws are roughly 11.8 in (30 cm) long and have four slender, tapering digits. Though its claws appeared to be made for ripping meat, the Therizinosaurs dinosaur was most likely a vegetarian that used its hands to defend itself and collect vegetation.

Is Nothronychus an omnivore?

A partial Nothronychus skull and postcranium have been found. It's possible that this strange theropod dinosaur evolved from a predator to a vegetarian.
