Phalarodon

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

Het geëet: VleisIgtiosourusseVroeë Trias tot Middel-TriasTegnies nie 'n dinosourus nie

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

Prettige feit: hierdie seereptiel het geswem terwyl dinosourusse op land geloop het. Almal noem hulle dino's, maar hulle was 'n ander tak van die reptiele.

Prettige feite

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

KI-prent van Phalarodon — 'n KI-prent van hoe Phalarodon dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

Mees gevraagde vrae oor 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

Vir dino-kenners

Wetenskaplike naam: Phalarodon
Benoem deur: Merriam 19103
Groep: Igtiosourusse
Familie / klade: Mixosauridae3
Klassifikasie: Ichthyosauria > Ichthyosauromorpha3
Ouderdom van die rotse: 251 tot 237 miljoen jaar ()3
Rotsformasies: Sulphur Mountain, Guanling, Jena3
Lande: Kanada, Duitsland, VSA, China, Svalbard3
Fossielrekords: 14 in The Paleobiology Database3
Ontdekking: 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
Steeds omstrede: 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
