Yayitya: IzityaloIidayinaso ezingaqhelekanga ezineentsibaiCretaceous yokuqala

Falcarius was a strange dinosaur that looked like a mix between an ostrich, a gorilla, and Edward Scissorhands! It had a small head, a long neck, and huge curved claws on its hands. This dinosaur lived in what is now Utah, USA, about 139 to 134 million years ago.1

izinto ezimnandi

Iinyani ezimnandi

Falcarius is one of the most primitive therizinosaurs ever found. It helps scientists understand how meat-eating dinosaurs turned into plant-eaters.2

Over 3,000 bones of Falcarius have been dug up from a single quarry in Utah. That's a lot of fossils!1

Falcarius had a long neck that let it reach leaves about 1.5 metres (5 feet) off the ground.1

Its hand claws were huge and curved, like sickles. That's how it got its name, which means 'sickle cutter'.1

Falcarius probably had feathers, like its close relatives from Asia.1

The smallest Falcarius was less than 1 metre (3.3 feet) long, but adults grew to about 4 to 5 metres (13 to 16 feet).1

Umfanekiso owenziwe yi-AI: Falcarius — Umfanekiso owenziwe yi-AI obonisa indlela Falcarius esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Falcarius

?How big was Falcarius?

About 4 metres (13 feet) long and about 1.4 metres (4.5 feet) tall at the hip, weighing around 100 kilograms (220 pounds). The smallest known individual was less than 1 metre (3.3 feet) long.1 4

?What did Falcarius eat?

Mostly plants. Its leaf-shaped, serrated teeth were good for shredding leaves, but the pointed front teeth suggest it might have also eaten small animals like lizards sometimes.1

?Did Falcarius have feathers?

Scientists think yes. No feathers were found with its fossils, but its close feathered relatives from China make it very likely Falcarius had shaggy, hair-like proto-feathers.4

?How fast could Falcarius run?

Probably not very fast. Its lower legs were stubby, which suggests it no longer needed to run after prey like its meat-eating relatives did.4

?Why did Falcarius have long claws?

Its huge, curved hand claws were like sickles, which gave it the name 'sickle cutter'. They were probably used for gathering plants or maybe for defence.1 4

?Where was Falcarius found?

In what is now Utah, USA, in the Cedar Mountain Formation. A huge bonebed there has yielded thousands of bones from hundreds of individuals.1 2

Usapho / iclade: Therizinosauria5
Ukuhlelwa: Theropoda > Therizinosauria5
Ubudala bamatye: 143 ukuya ku-133 izigidi zeminyaka (Berriasian / Valanginian)5
Izakhiwo zamatye: Cedar Mountain5

Ukufunyanwa: Falcarius was discovered in 1999 by fossil collector Lawrence Walker in Utah. Scientists named it in 2005.1
Kusaxoxwa ngayo: Scientists are not sure if Falcarius was a pure plant-eater or if it also ate meat. Its front teeth are sharp and pointed, which might mean it ate small animals too.1
