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 also 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 bis_size='{\"x\":12,\"y\":716,\"w\":576,\"h\":156,\"abs_x\":340,\"abs_y\":1004}'\u003e\u003cspan style=\"color: rgb(157, 83, 9);\" bis_size='{\"x\":12,\"y\":717,\"w\":101,\"h\":16,\"abs_x\":340,\"abs_y\":1005}'\u003e\u003cstrong bis_size='{\"x\":12,\"y\":717,\"w\":101,\"h\":16,\"abs_x\":340,\"abs_y\":1005}'\u003e Prognathodon\u003c\/strong\u003e\u003c\/span\u003e possessed a powerful and sturdy jaw designed to deliver a strong bite, fueled by muscular strength. Its teeth are particularly noteworthy—not only are they tough and perfectly suited for crushing, but detailed examination reveals serrations that enhance their effectiveness. This dual-function design allowed the teeth to break through tough protective shells while slicing through the flesh beneath. Additionally, bony rings around the eye sockets reveal a special adaptation for deep-water living, helping the eyes endure the increased pressure often faced when diving to hunt ammonites. This fossil showcases the incredible adaptations of a top prehistoric predator.\u003c\/p\u003e\n\u003cp bis_size='{\"x\":12,\"y\":889,\"w\":576,\"h\":195,\"abs_x\":340,\"abs_y\":1177}'\u003e Why \u003cspan style=\"color: #b45f06;\" bis_size='{\"x\":48,\"y\":890,\"w\":98,\"h\":16,\"abs_x\":376,\"abs_y\":1178}'\u003e\u003cstrong bis_size='{\"x\":48,\"y\":890,\"w\":98,\"h\":16,\"abs_x\":376,\"abs_y\":1178}'\u003ePrognathodon\u003c\/strong\u003e\u003c\/span\u003e 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 predator 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 number 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 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 bis_size='{\"x\":12,\"y\":1101,\"w\":576,\"h\":2,\"abs_x\":340,\"abs_y\":1389}'\u003e\n\u003cp bis_size='{\"x\":12,\"y\":1110,\"w\":576,\"h\":281,\"abs_x\":340,\"abs_y\":1398}'\u003e\u003cimg height=\"327\" width=\"681\" alt=\"2.4' Mosasaur Prognathodon Fossil Tooth Rooted In Matrix Cretaceous Dinosaur Era - Fossil Age Minerals\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1250\/0441\/files\/mosasaur_1_3639b7d3-2a8a-458b-87b5-283209ffe34e.jpg?v=1748980080\" bis_size='{\"x\":12,\"y\":1110,\"w\":576,\"h\":277,\"abs_x\":340,\"abs_y\":1398}'\u003e\u003c\/p\u003e\n\u003cp bis_size='{\"x\":12,\"y\":1407,\"w\":576,\"h\":319,\"abs_x\":340,\"abs_y\":1695}'\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/WRQ-RSNImIM\" height=\"315\" width=\"560\" bis_size='{\"x\":12,\"y\":1407,\"w\":560,\"h\":315,\"abs_x\":340,\"abs_y\":1695}' bis_id=\"fr_e8gr8wl6mrn1i1hqgi41hj\" bis_depth=\"1\" bis_chainid=\"1\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003chr bis_size='{\"x\":12,\"y\":1743,\"w\":576,\"h\":2,\"abs_x\":340,\"abs_y\":2031}'\u003e\n\u003cp bis_size='{\"x\":12,\"y\":1752,\"w\":576,\"h\":19,\"abs_x\":340,\"abs_y\":2040}'\u003e\u003cstrong style=\"color: #bf9000;\" bis_size='{\"x\":12,\"y\":1753,\"w\":274,\"h\":16,\"abs_x\":340,\"abs_y\":2041}'\u003ePlease be aware of the nature of fossils:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp bis_size='{\"x\":12,\"y\":1787,\"w\":576,\"h\":137,\"abs_x\":340,\"abs_y\":2075}'\u003eBeing buried under the ground for millions of years under tons of pressure tends to be rough.
