Phalarodon

Igama lithetha: “boss tooth, from Greek words for a cheek-plate boss and tooth”1

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

izinto ezimnandi

Iinyani ezimnandi

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

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

?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

Kwiingcali zeedayinaso

Igama lenzululwazi: Phalarodon
Inikwe igama ngu:: Merriam 19103
Iqela: Ii-ichthyosauri
Usapho / iclade: Mixosauridae3
Ukuhlelwa: Ichthyosauria > Ichthyosauromorpha3
Ubudala bamatye: 251 ukuya ku-237 izigidi zeminyaka ()3
Izakhiwo zamatye: Sulphur Mountain, Guanling, Jena3
Amazwe: iKhanada, iJamani, iUSA, iTshayina, iSvalbard3
Iirekhodi zeefosili: 14 kwi-Paleobiology Database3
Ukufunyanwa: 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
Kusaxoxwa ngayo: 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
