Phalarodon was a fast-swimming marine reptile that lived in the Triassic seas, not a dinosaur. It had a long body and a skull full of strong teeth for catching fish and squid.1

Phalarodon's name means 'boss tooth' because its teeth look like the boss on a helmet cheek-plate.1

It lived during the Middle Triassic, about 247 to 242 million years ago, when the supercontinent Pangaea was still together.1

Phalarodon could swim across the Tethys Ocean, as shown by fossils found in both Germany and China, which were on opposite sides of that ancient sea.1

Its skull had a high ridge on top called a sagittal crest, which helped anchor strong jaw muscles for a powerful bite.1

Some scientists think Phalarodon atavus had a skull up to 80 centimetres (2.6 feet) long, making it a large mixosaurid, but others say the fossils are too broken to be sure.1

Phalarodon shared its home with other marine reptiles like Cymbospondylus and Omphalosaurus in the Fossil Hill Member of Nevada.1

The teeth of Phalarodon were blunt and slightly flattened, perfect for crushing hard-shelled prey like ammonites.1

?How big was Phalarodon?

Scientists are not sure. Some estimate Phalarodon atavus could reach about 4.5 to 5 metres (15 to 16 feet) long, but others think it was only about 1 metre (3.3 feet) long like a small mixosaurid.1

?Could Phalarodon swim well?

Yes. A well-preserved fossil shows Phalarodon atavus was an adept swimmer that could cross the Tethys Ocean, since its fossils are found in both Germany and China.1 2

Go fitlhelwa: Phalarodon was named by John Campbell Merriam in 1910, based on a skull and jaw fragments found in the West Humboldt Range of Nevada, USA.1
Go sa ntse go ganetsanwa: Scientists still debate whether Phalarodon was a small mixosaurid about 1 metre long or a larger one reaching up to 5 metres, because many fossils are just skull pieces.1
