Saraikimasoom was a small, stocky long-necked dinosaur that lived about 72 to 66 million years ago in what is now Pakistan. It had a small skull, a long neck, a round body, and short legs, making it one of the smallest titanosaurs ever found in the Indo-Pakistan region.2 1

酷東西

趣味知識

Saraikimasoom had a very small skull, only about 15 to 18 centimeters long and 7 to 9 centimeters high, which is tiny for a dinosaur of its size.1

Its teeth were small, circular, and slightly curved, and they tapered gradually from base to tip, unlike some other titanosaurs whose teeth were more uniform.1

The skull's upper and lower tooth rows were U-shaped, which is a feature shared with its close relative Gspsaurus, but unlike Gspsaurus, the lower tooth row was also U-shaped.1

It had a dental formula of 4, 13/9 to 13, meaning it had 4 premaxillary teeth, 13 maxillary teeth, and 9 to 13 dentary teeth on each side.1

Saraikimasoom is the smallest titanosaur known from the Indo-Pakistan subcontinent, and it was a stocky animal with a round body and short legs.1

Its tail vertebrae were procoelous (hollow in front), except for the first one which was biconvex, a feature that helps scientists classify it as a titanosaur.1

The name Saraikimasoom comes from the Saraiki language, where 'masoom' means innocent, and the species name 'vitakri' honors the Vitakri Formation where it was found.1

?Was Saraikimasoom a dinosaur?

Yes, it was a small, stocky sauropod dinosaur from the Late Cretaceous.1 3

?What did Saraikimasoom eat?

It was a plant-eater. Its small, conical teeth were good for stripping leaves and soft plants.1

?When did Saraikimasoom live?

It lived about 72 to 66 million years ago, during the very end of the Cretaceous Period.3

?Where was Saraikimasoom found?

Its fossils were discovered in the Vitakri Formation of Balochistan, Pakistan.1 3

?Is Saraikimasoom the smallest titanosaur?

It is the smallest titanosaur known from the Indo-Pakistan subcontinent, but scientists are not sure if it is the smallest of all titanosaurs.1

?Why is it called Saraikimasoom?

The name comes from the Saraiki language of Pakistan, where 'masoom' means innocent. The species name 'vitakri' honors the Vitakri Formation where it was found.1

迷思破解王

迷思： Some people think all titanosaurs were giant, but Saraikimasoom was actually quite small for a titanosaur.

真相： Saraikimasoom was about 8 to 10 meters long and weighed about 5 tons, which is small compared to giants like Argentinosaurus, but still big compared to a car.1

發現: Saraikimasoom was first described by M. S. Malkani in 2014, based on a partial skull and other bones found in the Vitakri Formation of Balochistan, Pakistan. The type specimen is stored in the museum of the Geological Survey of Pakistan in Quetta.2 1
仍有爭議: Scientists still debate whether Saraikimasoom belongs in its own family, Gspsauridae, or if it is a more primitive titanosaur, and some details of its skull and teeth are still being studied.2 1
