Balaenognathus was a flying reptile that lived about 150 million years ago. It had a strange, spoon-shaped snout with hundreds of tiny hooked teeth. It used its beak like a strainer to scoop up tiny shrimp from the water, just like a modern flamingo.1 2

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

izinto ezimnandi

Iinyani ezimnandi

Balaenognathus had at least 480 teeth, more than most other pterosaurs.1

The tips of its teeth had tiny hooks, which have never been seen in any other pterosaur. These hooks helped trap shrimp so they couldn't escape.1 2

The front of its snout was shaped like a spatula and had no teeth, so water could flow in easily.1

Its upper jaw was more curved than its lower jaw, so its mouth stayed slightly open at the front even when closed.1

The fossil was found by accident in a quarry in Germany, inside a block of stone that also contained bones of a crocodile-like animal.1 2

Balaenognathus lived during the Late Jurassic period, about 152 to 149 million years ago.3

It had long legs, which helped it wade through shallow seas while feeding.2

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

?What did Balaenognathus eat?

It ate tiny shrimp and other small plankton. It used its spoon-shaped beak and hundreds of tiny hooked teeth to strain them out of the water.1 2

?How big was Balaenognathus?

It was a medium-sized pterosaur with a wingspan of 1.17 metres (3.8 feet). Its body was about 1 metre long.5

?Why did Balaenognathus have so many teeth?

Balaenognathus had over 480 long, slender teeth with tiny hooks at the tips. These teeth formed a fine mesh like a net to trap tiny shrimp while letting water escape.1 2

Kwiingcali zeedayinaso

Igama lenzululwazi: Balaenognathus
Inikwe igama ngu:: Martill et al. 20236
Iqela: Izirhubuluzi ezibhabhayo
Usapho / iclade: Ctenochasmatidae6
Ukuhlelwa: Pterosauria > Pterodactyloidea6
Ubudala bamatye: 152 ukuya ku-149 izigidi zeminyaka (Kimmeridgian)6
Amazwe: iJamani6
Iirekhodi zeefosili: 1 kwi-Paleobiology Database6
Ukufunyanwa: Balaenognathus was named by David Martill and colleagues in 2023. The only known fossil was found in September 2011 in a quarry near Wattendorf, Bavaria, Germany, by workers collecting a block of limestone.1
Kusaxoxwa ngayo: Scientists are not sure exactly how Balaenognathus used its hooked teeth and spatula-like snout to filter food, but they think it may have pumped water in and out by moving its long neck.1
