This theory is especially plausible given the body size to flipper size ratio of mosasaurs that would make it extremely difficult for them to leave water and lay eggs like sea turtles do. v=1575217633","options":["Size"],"media":[{"alt":null,"id":5806395457619,"position":1,"preview_image":{"aspect_ratio":1. v=1638890853","width":1200},{"alt":null,"id":5806466465875,"position":4,"preview_image":{"aspect_ratio":1.
Mosasaurs lived during the late Cretaceous Period, about 100 million years ago and lasting until 65 million years ago. Globidens species were able to make short work of shelled prey and many ammonites met an untimely demise between mosasaur jaws.

While this evidence alone suggests the Mosasaurs were formidable predators, a spectacular new find in Jordan has revealed that Mosasaurs were "countershaded" with darker pigmentation on the top and lighter on the bottom.
Mosasaurs were a very successful group during the Cretaceous and grew to become some of the largest marine reptiles ever. These are all terms you’ll find in the scientific literature that describe the tooth base in a mosasaur and they all imply different evolutionary and developmental scenarios.Considering that most mosasaurs were the largest creature in their environment, it's safe to assume that they ate nearly everything else that was smaller than them.
with a length range and photos showing most of them having intact tips and others being repaired, I wasn't expecting it to be perfect. For expediency’s sake mosasaur teeth can be divided into three categories: feeding generalist, pursuit predator and crushing. Once a tooth was broken or inadequate for its size, they would drop it and eventually a new tooth would replace it.Coincidentally, one of the breakthroughs for my PhD thesis was a study by my Master’s supervisor, Mike Caldwell and colleagues Lisa Budney, and Denis Lamoureux in 2003 (see the list of papers at the start of the post). These figures are truly massive though fall short of the length of the Mosasaurus that was depicted in the film, Jurassic World. The Family is divided into subfamilies and many genus and species based on differences in their bodies. While this arrangement probably allowed a Mosasaur to swallow prey whole, the alignment of a Mosasaur's teeth with "bony crypts" to protect emerging teeth also suggests Mosasaurs likely crushed bones as frequently as they tore into flesh. It makes clear sense to me now as I saw a lot of mosasaur jaw fakes around and this lead me to think that the tooth might also be fake!
From that point forward the scientific community had a baseline to further classify and rearrange mosasaurs as more fossils were exhumed. It’s also important to note that the debate over this has carried on for nearly 20 years following his work, so even if it seems like a cut-and-dry, problem-solved type question, this serves as a reminder of how science works: by testing and re-testing hypotheses until the strongest one is left standing.Thecodonty is a term usually reserved for the teeth of mammals and crocodilians, where the teeth are deeply implanted into discrete sockets along the jaws. It is for this reason that many paleontologists emphasize that they were scourges of shallow seas - signifying the reptiles' need for easy air availability. An excellent example of crushing teeth are present in Globidens mosasaurs, such as those in the genus, Igdamanosaurus. Some think that mosasaurs are most closely related to monitor lizards (things like the Komodo dragon), but others contend that mosasaurs are actually marine relatives of snakes (and from this came an idea that the common ancestor of snakes and mosasaurs came from the water)! This style of tooth is extremely useful for capturing agile prey underwater, though not all mosasaurs exhibited teeth of this variety.
