Yes, mosasaurs are extinct. They were a group of large marine reptiles that thrived during the Late Cretaceous period, around 70 to 66 million years ago. Their extinction coincided with the mass extinction event that also wiped out the dinosaurs. Today, they are known only from fossil records.
Mosasaur fossils are the remains of large, extinct marine reptiles called mosasaurs that lived during the Late Cretaceous period. These fossils include teeth, bones, and sometimes even preserved soft tissues, providing valuable information about the biology and evolution of these creatures. Some notable mosasaur species include Mosasaurus and Tylosaurus.

The Hainosaurus at up to 17 meters (57 feet) long
Tylosaurus was not a dinosaur. It was a type of mosasaur, which were large, carnivorous marine reptiles.
Mosasaurus hofmannii is probably the largest mosasaur, perhaps reaching a length of more than 17 meters (60 feet). Tylosaurus and Hainosaurus reached similar lengths but were less robust, probably only weighing half what Mosasaurus hofmanni of the same length weighed.
it weighs around 2,500 pounds it usually is also 30 or more feet to meters
