The Mosasaurs the Last Grand Marine Reptiles

In the late 1700s a giant skull was discovered in the Netherlands. It belonged to a group of long extinct sea monsters known as mosasaurs but at the time dinosaurs hadn't even been discovered and science as we know it was still in its infancy. It turns out that all though this was one of the first prehistoric creatures known to science they were actually one of the last groups of giant marine reptiles to rule over the ocean.

    Late 1700s... He didn't have access to "modern science", but he did have access to monitor skulls. ;) Compare the skull of a mosasaur to the skull of a monitor and it's not that difficult to see that they're probably closely related. Besides, tiny nitpick here - in the late 1700s, science of the late 1700s would've been considered modern

    Remember their shells were ballasts which could be filled with air allowing them to adjust their buoyancy it has been hypothesized that like modern squid they may have evolved to use ammonia gas to control buoyancy. In particular like modern squid the lack of soft fossil preservation under Lagerstatten conditions stands out as unusual given that their fully soft bodied cousins were able to be exceptionally well fossilized under those conditions preserved down to the detail of individual melanosomes. Interestingly there has been a recent potential fossil ammonite and it notably lacks its shell (i.e. the animal's shell was separated from it after death. If the shell was a ammonia ballast this would be expected since it would allow the animal's remains to become acidic to resist decomposition. The ammonia hypothesis is based off of modern squid which use ammonia within their soft bodies to control their buoyancy after having lost their hard shell a change which occurred during the early Cenozoic likely driven by the evolution of echolocation within cetaceans. It is notable that squid around this time completely disappear from the fossil record in their entirety. However as squid are very much still around in our oceans we know they didn't go extinct. It has since been discovered that the ammonia they used to maintain buoyancy within their bodies rather than contained within a shell like the ammonites would have likely done. Experiments have verified that the ammonia prevents the conditions needed for fossilization to occur and assisting in the decomposition of the animal after death even under ideal fossilization conditions thus we have direct evidence that the adaptation of ammonia is a very real possibility for cephalopods since it has evolved at least once. While much of ammonite biology is poorly understood the few samples of ammonite feeding apparatus suggest very fine comb structures rather than a predatory beak suggesting that at least some ammonites were suspension feeders/filter feeders.

Basically it prevents all forms of soft bodied fossilization. The gas is buoyant in water making it a natural solution for evolution to select as a lifting gas but the consequence is that unless any organism which evolves to adapt this mechanism of buoyancy has mineralized parts we will never be able to know it existed as even the perfect soft bodied fossilization conditions will fail to fossilize (i.e. the ammonia destroys the dead organism resulting in amorphous organic sludge preventing fossilization)

Prior to that, and going all the way back to the classical era, B. C. times, fossils were regarded as the remains of gods, demi-gods, great heroes like Achilles and Hercules and mythical beasts like cyclops, dragons, chimeras, hydras and krakens and so on.

    The fact that mosasaurs are surprisingly closely related to living families of lizards has made me wonder why no reptiles tried to fully adapt to marine ecosystems again after the K-PG Extinction. Early Paleogene oceans would have seemed like a perfect environment for a lizard or crocodilian to take advantage of a world where virtually all large Mesozoic predators had gone extinct and many ecological niches were available, and mammals still weren't diverse enough to try and make a livelihood out at sea yet. The Paleogene Thermal Maximum in particular would've seemed like a perfect time for a new resurgence of marine reptiles, and while marine mammals likely would have eventually superseded them as global temperatures cooled in later epocks the fact there were no major reptilian evolution experiments in the Cenozoic oceans has always felt very strange to me.

What I'm saying is there was no adaptive radiation that created a massive biodiversity that fundamentally shaped the dynamics of ocean ecology like icthyosaurs, plesiosaurs, and mosasaurs did in the Mesozoic and what cetaceans would eventually do in the Cenozoic. There was roughly a 15 million year gap at the start of the Cenozoic where the ancestors of whales hadn't evolved enough adaptations for a long-term ocean existence that lizards or crocodilians could have exploited to firmly cement their presence in the global ocean biosphere again before the first true whales evolved, yet they never did for unknown reasons.

    Sea kraits are snakes, but they are not directly related to true sea snakes. Sea snakes and sea kraits were two independent lineages of snakes that separately adapted to ocean life through convergent evolution. The key difference between them is that true sea snakes give live birth, while sea kraits lay eggs in sea caves with air pockets.

Its been found that Tegus and pythons ramp up their metabolism during mating season, so warm bloodedness might have evolved for mating purposes.

    Ichthyosaurs, pliosaurs & plesiosaurs all preceded mosasaurs, but the latter replaced them. Is it possible that mosasaurs were venomous? Their snake relatives, and possibly Komodo monitors, are. That would give them an edge, but would it fossilise?

    Komodo dragons don't produce venom. instead they have very toxic bacteria in their saliva, just like modern house cats. I know it may sound like I'm splitting hairs but venomous implies that a creature produces the venom itself.

    Mosasaur venom seems unlikely because they do not have the features associated with venom in living animals, and while venom is widespread in the group of squamates mosasaurs are a part of, medically significant venoms used in hunting is much rarer, with most of them using their venom as part of the process of digesting already captured food.

    I'd always assumed mosasaurs were related to the plesiosaurs and pliosaurs. when he started calling them 'lizards' I was like... 'wait a moment... he doesn't seem the sort to make that kind of rookie error...' But I was the one with a gap in my knowledge. I'm actually astounded that they're genuinely thought to be closer to lizards than the other large Mesozoic predatory reptiles. A really astounding example of convergent evolution. Would be nice to know what (if any) evidence there is or interactions between mosasaurs and the superficially similar pliosaurs during the periods they overlapped.

Dogs VS Cats come to mind when the continents joined but that is 2 well established predators in direct competition. While in this case, they started off as small amphibious reptiles and somehow grew to dominate the oceans, what would give them such huge advantage that they climbed all the way to the top of the food chain when there were plenty of massive sea predators? Please share your wisdom.

    The title is interesting: "The Mosasaurs the Last Grand Marine Reptiles" Thing is, the saltwater crocodile is a "grand" marine reptile in it's own right, reaching lengths of over 20 Ft. But unlike the mosasaurus it's actually still alive and thriving today. I don't think the saltwater crocodile is appreciated enough. It's practically a living breathing fossil that's been around since the dinosaurs and other prehistoric marine reptiles.

    The maximal shell diameter of a discovered Parapuzosia seppenradensis partial shell was extrapolated to be a whopping 4,50 meters when complete.That's the biggest of the few that were found from this species. So realistically, one could expect even bigger shell diameters from this kind of cephalopod.
