Ikhadi ledayinaso No. 1501 kwe-2 027

Pterorhynchus

Igama lithetha: “wing snout”1

Yayitya: IintlanziIzirhubuluzi ezibhabhayoiJurassic ephakathiNgokwenene ayisiyo dayinaso

Pterorhynchus was a flying reptile that lived about 164 million years ago, during the Jurassic Period. It had a big crest on its head and a long tail, and it flew over ancient China.1 4

Inyani emnandi: iipterosauri zazibhabha phezu kweedayinaso, kodwa zazingabazala bazo, hayi iidayinaso ngokwazo.

izinto ezimnandi

Iinyani ezimnandi

Pterorhynchus had a head crest made of both bone and soft tissue, which was unusual for long-tailed pterosaurs.1 2

Its body was covered in hair-like structures called pycnofibers, which may have helped keep it warm.1

The tail of Pterorhynchus was about as long as its wing, and it had a diamond-shaped flap at the end.1 2

The head crest was so large that scientists think it helped the animal steer while flying, like a rudder.2

The only known fossil is a nearly complete skeleton with preserved skin and other soft parts.1

The crest may have had a camouflage pattern, based on vertical stripes seen at its base.1

Umfanekiso owenziwe yi-AI: Pterorhynchus — Umfanekiso owenziwe yi-AI obonisa indlela Pterorhynchus 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: Pterorhynchus

?How big was Pterorhynchus?

Pterorhynchus had a wingspan of about 85 centimetres (33 inches) and a skull about 11.8 centimetres (4.6 inches) long.1 3

?What did Pterorhynchus eat?

Its robust teeth suggest it ate small animals, possibly including fish and insects, though the exact diet is not known for sure.3

?Did Pterorhynchus have feathers?

Pterorhynchus had hair-like pycnofibers covering its body, not feathers. Some scientists think these might be related to dinosaur feathers, but this is debated.1

?Why did Pterorhynchus have a crest?

The crest likely helped with steering during flight, acting like a rudder, and may have had a camouflage pattern.1

Inyaniso ngeentsomi

Intsomi: Pterorhynchus was a dinosaur.

Inyaniso: Pterorhynchus was a pterosaur, a flying reptile that is not a dinosaur.1
