it's just fancy fancy talk that states that the animal displayed in Jurassic world has a series of traits from animals of little relation and dissimilar evolutionary adaptions.
anyway, it's been a while since i displayed another drawing here hasn't it? lets fix that, shall we?
heres helicoprion.
the famous ancient shark with one of natures most wicked jaw apparatus. this shark possibly went through more reconstructions then any other shark. this due o it's odd, spiraled row of teeth. such teeth and mouth design has absolutely no analogue with out extant fauna, therefore scientist ere stumped on how this mouth would of operated.it was only fairly recently did we found out that it's teeth can spin backwards to a limited degree in a chainsaw like fashion. when prey is caught, such as this squid, the teeth would rotate backwards, sawing and sending the unfortunate prey item into it's throat.
and heres cretoxyrhina mantelli
the prehistoric ginsu shark. both predator and prey to the mosasaur species it coexisted with at the time. compared to other prehistoric sharks, this is possibly the most well understood. known from exceptionally well preserved remains( which is very rare for any cartilaginous fish) measuring 6- 7 meters in length, this large shark on average is around as big as a record breaking great white. it has given direct evidence of this shark at the very least, scavenged off bodies of mosasaurs (although, squalicorax is another possible candidate.). ectenosaurus was also very small for mosasaur standards, so this being an example of predation is also credible.
