Pterodaustro

Igama lithetha: “wing from the south”1

Pterodaustro was a flying reptile that lived near lakes in what is now Argentina. It had a weird mouth with about 1,000 long, bristle-like teeth in its lower jaw, just like a comb! It used those teeth to strain tiny shrimp and other small animals from the water, just like flamingos do today.1 2

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

izinto ezimnandi

Iinyani ezimnandi

Pterodaustro had about 1,000 teeth in its lower jaw, each only 0.2 to 0.3 millimeters wide. That's thinner than a human hair!1 2

Scientists have found over 750 fossils of Pterodaustro, including eggs and embryos, making it one of the best-known pterosaurs.1

Pterodaustro had a long tail with 22 vertebrae, which is unusual for a pterodactyloid pterosaur. Most others have at most 16.1

Two Pterodaustro fossils were found with gizzard stones in their stomachs. These are the first gizzard stones ever reported for any pterosaur.1

Pterodaustro may have been pink like a flamingo! Its diet of tiny crustaceans could have given it a pink color, just like flamingos get from eating brine shrimp.1 2

Pterodaustro had a hard time taking off from the ground. Because of its long body and short legs, it needed a lot of open space to launch, like modern geese and swans.1

Juvenile Pterodaustro grew quickly in their first two years, reaching about half of adult size. They then grew more slowly for four to five years until they were fully grown.1

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

?How big was Pterodaustro?

It had a wingspan of about 3 metres (9 ft 10 in) and weighed about 9.2 kilograms (20 lb).1

?Is Pterodaustro a dinosaur?

No, it is a pterosaur, which is a flying reptile, not a dinosaur.1 4

?What did Pterodaustro eat?

It ate tiny shrimp, crustaceans, and other small water animals. It used its comb-like teeth to strain them from the water, just like flamingos do.2 1 4

?Could Pterodaustro swim?

Yes, it had a long body and large, splayed feet that were adaptations for swimming and wading in lakes.1

?Why did Pterodaustro have so many teeth?

Its lower jaw had about 1,000 long, bristle-like teeth that formed a comb. This comb helped it filter tiny animals like shrimp out of the water.2 1 4

?Was Pterodaustro pink?

Maybe. Scientists think it could have been pinkish just like flamingos, because its diet of brine shrimp might have given it that color.2 1

Inyaniso ngeentsomi

Intsomi: Pterodaustro was a dinosaur.

Inyaniso: Pterodaustro was a pterosaur, a flying reptile that lived at the same time as dinosaurs but is not a dinosaur.1

Kwiingcali zeedayinaso

Igama lenzululwazi: Pterodaustro
Inikwe igama ngu:: Bonaparte 19705
Iqela: Izirhubuluzi ezibhabhayo
Usapho / iclade: Lophocratia5
Ukuhlelwa: Pterosauria > Pterodactyloidea5
Ubudala bamatye: 121 ukuya ku-100 izigidi zeminyaka (Aptian / Albian)5
Izakhiwo zamatye: Lagarcito, La Cruz5
Amazwe: i-Argentina5
Iirekhodi zeefosili: 2 kwi-Paleobiology Database5
Ukufunyanwa: The first fossils of Pterodaustro were discovered in the late 1960s by paleontologist José Bonaparte in the Lagarcito Formation of San Luis Province, Argentina. Bonaparte named the genus in 1970, with the species name P. guinazui honoring Román Guiñazú.1
Kusaxoxwa ngayo: Scientists are still debating whether Pterodaustro was actually pink like a flamingo. While its diet suggests it could have been, no direct fossil evidence of color has been found.1 2
