This means that Prognathodon specialized in eating tough-shelled prey items like shellfish, ammonites, and turtles. The diet of Prognathodon was for a long time just speculation based upon the teeth and jaw construction, but two discoveries in Canada in the early years of the twenty-first century not only revealed the full body shape of Prognathodon but the diet as well. One specimen revealed the presence of turtle and ammonite fossils located where its stomach would have been. Interestingly, it also had a one-hundred and sixty centimeters long fish in its gut, suggesting that while Prognathodon was a specialized predator, it was also opportunistic in its feeding.\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\"\u003e\u003cstrong\u003e\u003cspan style=\"color: #b45f06;\"\u003eHoffmanni\u003c\/span\u003e\u003c\/strong\u003e had a robust and heavy jaw that would have been capable of withstanding a high bite force supplied by powerful jaw muscles. However, it’s the teeth that should receive special note, as not only are they strong and well adapted for crushing, they have serrations that can be seen under much more detailed inspection. This makes the teeth specialized for a dual purpose, destroying the protective shells of prey while shearing the flesh within. Another specialization is the presence of bony rings around the eye sockets. This is seen as a deep water adaptation for the eyes to better withstand the higher water pressure of deep water, something which may have often been necessary when diving for ammonites.\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\"\u003e Why Hoffmanni shifted towards this kind of diet when mosasaurs are generally perceived to be apex predators of other reptiles and fish remains uncertain. It could have been that competition for the ecological niche of apex predators was so fierce that the only way Prognathodon could evolve and survive was by adapting to a different food source, removing the need for competition with other predators. It could also be that the numbers of large prey animals that mosasaurs are traditionally associated with began to fall, necessitating a need to switch to a different diet. It could have course been to simply exploit an abundant food supply. What is certain is that Prognathodon was not the only mosasaur to adjust to this diet, with another named Globidens also having particularly large and rounded crushing teeth in its mouth\u003c\/p\u003e\n\u003chr id=\"horizontalrule\"\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1250\/0441\/files\/mosasaur_1_3639b7d3-2a8a-458b-87b5-283209ffe34e.jpg?v=1754184210\" alt='10.5\" Mosasaur Prognathodon Fossil Jaw In Matrix Teeth Cretaceous Dinosaur Era COA - Fossil Age Minerals'\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/WRQ-RSNImIM\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e \u003cstrong style=\"color: #bf9000;\"\u003ePlease be aware of the nature of fossils:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBeing buried under the ground for millions of years under tons of pressure tends to be rough.
