Globidens was a large mosasaur with a bite force of 9.7 tons, the strongest bite of any mosasaur species. It grew up to 20 feet long and weighed 2 tons. Prognathodon, a relative of Globidens, had a strong bite as well. It is longer but not heavier. Globidens lived from 75-67 million years ago in Africa, Asia, and North America. Globiden’s name means globe tooth. Globidens preyed on large armoured prey such as turtles and ammonites which would be the reason why it had such a massive bite force. Globidens would have been preyed on by larger mosasaurs where it lived and it would have not been a particularly fast swimmer. It did have scleral rings meaning that it either hunted at night, in the depths or both. This would might mean that it avoided other mosasaurs by choosing a different diet and hunting when or where other mosasaurs didn’t.
