Atopodentatus was a weird marine reptile that lived in the sea about 245 million years ago. It had a hammer-shaped head and used its special teeth to scrape algae off rocks, like a underwater lawnmower.2

1

Atopodentatus is the oldest known plant-eating marine reptile. It lived about 6 million years after the great Permian extinction.2

2

Its head was shaped like a hammer, similar to a hammerhead shark. But Atopodentatus used its hammerhead for grazing on algae, not for sensing prey.2

3

The front of its jaws had chisel-shaped teeth for scraping algae. The back of its jaws had a mesh of needle-shaped teeth that acted like a strainer.2

4

Atopodentatus was about 2.75 meters (9 feet) long, about as long as a small car.1

5

Scientists first thought Atopodentatus had a downturned snout and was a filter feeder. But new skulls in 2016 showed it actually had a hammerhead.1

6

Atopodentatus lived in shallow seas near the coast, where algae grew on rocks. It probably could walk on land or mudflats.1

Dipotso tse botswang haholo ka Atopodentatus

?What did Atopodentatus eat?

Atopodentatus ate algae, scraping it off rocks with its chisel-shaped front teeth and filtering the bits with needle-like teeth in the back of its mouth.12

?How big was Atopodentatus?

Atopodentatus was about 2.75 meters (9 feet) long, roughly the size of a large dog.1

?Was Atopodentatus a dinosaur?

No, Atopodentatus was a marine reptile called a sauropterygian, not a dinosaur. It lived in the sea, not on land.1

?Why did Atopodentatus have a hammer-shaped head?

The hammer-shaped head helped Atopodentatus scrape algae off the seabed. Its wide jaws had chisel-like teeth for scraping, and the shape was unique among marine reptiles.21

?When did Atopodentatus live?

Atopodentatus lived about 247 to 240 million years ago, during the Middle Triassic period, about 6 million years after the Permian extinction.1

?Could Atopodentatus walk on land?

Scientists think Atopodentatus was semi-aquatic and could probably walk on land or mudflats, based on its body structure.1

Mosenyi wa ditshomo

Tshomo: Atopodentatus was a filter feeder that sucked up small animals from the seafloor.

Nnete: New fossils show it had a hammer-shaped head and used its front teeth to scrape algae, then filtered the plant bits through its back teeth. It was a plant eater.2

The first fossil of Atopodentatus was found near Daaozi village in Yunnan, China. Scientists named it in 2014. The name means 'unusual tooth' because of its strange teeth.1
E sa ntse e phehwa kgang
Scientists are not sure exactly how Atopodentatus is related to other marine reptiles. It is considered a strange type of sauropterygian.2
