ደስ ዝብሉ ሓቅታት

Natovenator had a streamlined body, which is very rare for non-avian dinosaurs. Its ribs pointed backwards to make it more hydrodynamic, just like diving birds and mosasaurs.2 1

It had 13 teeth in its premaxilla (the front of the upper jaw), which is an unusually high number for a dromaeosaurid.2 1

Its snout was long and full of many small holes (neurovascular foramina), which may have helped it sense movement in the water.2 1

Natovenator belongs to a group called Halszkaraptorinae, which are dromaeosaurids that may have been semi-aquatic. This group includes Halszkaraptor from Mongolia.1 3

Its neck was long, like many diving birds today, which helped it catch fish quickly.1

The name Natovenator means 'swimming hunter' in Latin, because scientists think it was a good swimmer that hunted in water.1

The only known fossil of Natovenator was found in the Baruungoyot Formation, which is about 72 to 83 million years old.3 1

ብዛዕባ Natovenator ብብዝሒ ዝሕተቱ ሕቶታት

?How big was Natovenator?

About 0.7 metres (2.3 feet) long and weighed around 0.3 kilograms (0.66 pounds). That is roughly the size of a duck.1

?Could Natovenator swim?

Yes, scientists think it was a good swimmer. Its ribs pointed backwards to make its body streamlined like a diving bird, and its long neck helped it catch fish.2 1

?What did Natovenator eat?

It likely ate fish and other small prey in the water. Its many sharp teeth and long snout were good for catching slippery food.1 2

?When did Natovenator live?

It lived during the Late Cretaceous, about 72 to 83 million years ago, in what is now the Gobi Desert of Mongolia.1

ጽውጽዋይ ዘፍርስ

ጽውጽዋይ: Some people think all dromaeosaurids were fast runners that lived only on land.

ሓቂ: Natovenator shows that some dromaeosaurids, like those in the Halszkaraptorinae group, were adapted for swimming and may have spent much of their time in water.1 2

ርኽበት: Natovenator was named in 2022 by Sungjin Lee and colleagues based on a nearly complete skeleton found in Mongolia. The fossil was first mentioned in a 2019 abstract.1 2
ገና ዘከራኽር: Scientists are still debating whether all halszkaraptorines were semi-aquatic, or if some were more terrestrial. Natovenator's streamlined body supports the swimming idea, but more fossils are needed to be sure.1 2
