Sarabosaurus was a small, ancient marine lizard that swam in a warm sea that once covered the middle of North America. It lived about 94 million years ago, during the time of the dinosaurs, and is the oldest mosasaur ever found in that region.1 2

Inyani emnandi: esi sirhubuluzi saselwandle sasiqubha ngelixa iidayinaso zazihamba emhlabeni. Wonke umntu uzibiza ngokuba ziidayinaso, kodwa zazilisebe elahlukileyo lezirhubuluzi.

izinto ezimnandi

Iinyani ezimnandi

Sarabosaurus is the oldest mosasaur known from the Western Interior Seaway, dating to about 93.7 million years ago.1

The only known specimen was a mature adult, only 3 to 4 years old when it died.1

Its name comes from the Arabic word 'sarab' meaning desert mirage, because the sea it lived in has long since vanished.1

Sarabosaurus had a unique blood supply to its brain, different from most lizards, similar to how whales evolved.2

The species name 'dahli' honors Steve Dahl, a volunteer who helped collect fossils at the monument.1

Scientists used micro-CT scanning to study the braincase and map the blood vessels of Sarabosaurus.2

Sarabosaurus was about 3 metres (9.8 feet) long, small compared to later giant mosasaurs.1

Umfanekiso owenziwe yi-AI: Sarabosaurus — Umfanekiso owenziwe yi-AI obonisa indlela Sarabosaurus esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Ukufunyanwa: The fossil was discovered in March 2012 by volunteer Scott Richardson in the gray shale of Utah. It was named in 2023 by Michael Polcyn and colleagues, with the species named after volunteer Steve Dahl.1 2
Kusaxoxwa ngayo: Scientists are still debating exactly how Sarabosaurus is related to other early mosasaurs, especially its position in the family tree.1
