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

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
