Millions of years ago there lived a fearsome shark that fed on almost anything it came across, including mosasaurs, plesiosaurs, pterosaurs and even dinosaurs...
*Yes it's a Mosasaur in the thumbnail, not a dinosaur.

I still find it stunning that sea turtles survived all these terrible predatory monsters.

@WaterShowsProd 4 года назад

Sea turtles have survived every fearsome beast, every mass extinction, every shift in the continents, then some weird monkeys started building resorts on their hatching grounds and tangling them in nets. :(

@WaterShowsProd 3 года назад

@Drake Petty Granted my use of "every mass extinction" was hyperbole. I thought they dated back further, but you're right. The sea turtles of The Jurassic are not related to extant sea turtles, so that group didn't survive. Thanks.

@WaterShowsProd 3 года назад

@Drake Petty I used to collect horseshoe crab shells in Massachusetts and was amazed by them as a kid. Also collected a few whale vertebrae. Now I live in Bangkok and was stunned the first time I saw people eating horseshoe crab. On a happier note, when my parents came to visit I took them to the aquarium and my father was thrilled to see nautiluses. He said he thought he would never have an opportunity to see them in real life.

@dasaniwater1618 3 года назад

I mean some ancient turtles reached up to 5 meters in length which means the predators couldn’t swallow them and actually had to break their 2 inch thick shells. Imagine trying to eat a 2 inch thick bone plate made that’s almost your size. Also they had really sharp and powerful beaks that they would just take chunks of flesh and bone off while you’re trying to get past the shell

A shark that eats dinosaurs? That's an awfully long way to say "f*cking metal"

@CJCroen1393 4 года назад

Another fact about sharks that is fucking metal: They love heavy metal because the low-frequency vibrations sound like the sounds made by struggling fish. Or, as tumblr user mlgspacememe worded it, "Sharks love heavy metal because it sounds like their dying prey". In short, sharks are nature's ultimate badasses.

If you think about it, if great whites were extinct we may be saying the same. (10-20 foot highly predatory fish with 1-2 inch razor sharp super serrated teeth that can just end our life in the blink of an eye if it felt like it...) Think perspective of what we're use to is huge, but suppose it makes sense we look at the brighter sides of death / a long gone scary creature while perhaps overlooking how many animals, for all intents and purposes, can just about as easily take out people

The reason the Cretoxyrhina died out is for the same exact reason the Megalodon did. As you said, it was competition but not with the adults. The young of these two species of sharks were very vulnerable towards other predators that evolved into the scene. As fewer and fewer young survived into adulthood, their species became unable to sustain themselves.

Sigh, if want to be completely unbiased, and much as I'm a vertebrate lover, we have forever been in the age of invertebrates (make up 95 percent of all animal life). But we don't realize it because animal books, tv shows, etc. focus 95% on vertebrates (fish, reptiles, mammals, amphibians, birds, dinos). Tho imo earth has nearly always been in the age of diversity, since no one or 2 group dominates every ecosystem. We tend to focus on mega faunal groups, but really if account for total biomass, species diversity, etc. less biased criteria, the "less interesting groups" are really in control of the planet (bacteria, fungi, plants, insects, etc. etc.) Not to say we can't have our own preferences :P

@nickporter4279 4 года назад

Is there a reason why the term "shark" is so commonly used to refer to any cartilaginous fish that's not a ray or a holocephalian? It's the most prominent use of a paraphyletic grouping that I know of, aside from "fish" itself. What makes it weirder is that all living sharks fit neatly into a crown group in Selachii or Selachimorpha, which appears to have its origins some way into the Mesozoic. Why isn't this the common definition?

@nickporter4279 4 года назад

(Just to be clear, not referring to Cretoxyrhina itself which is a shark by any definition, just the "sharks have been around for 400 million years" bit that always triggers my nerd radar whenever I hear it.)

@Ozraptor4 3 года назад

Because the vast majority of people (including non-zoologist scientists) need terms to describe things they encounter in their day-to-day lives outside of any pedantic need for monophyletic groupings. Hence we will always have need of biological terms which represent either paraphyletic or polyphyletic grade = fish, shark, amphibian, tree, bush, gamefish, waterfowl, invertebrate, worm, microbe etc.

@@Ozraptor4: do you encounter non-selachian, non-holocephalian, non-batoidian cartilaginous fish in your day-to-day life? I would be rather surprised, given that only one possible dorsal spine is known from within the last 66 million years.

The ginsu shark? Say, could it cut apart a tin can and still be sharp enough to slice bread?

@themightynanto3158 Год назад

Most badass shark ever. Imagine the odds it had to face to survive. It lived alongside giant marine monitor lizards that were twice its size, and with ravenous fish such as Xiphactinus. Plus it ate dinosaurs and pterosaurs for lunch. How cool is that?

I’ve also read somewhere of an artist on deviantart by the name Hodarinundu That mentions that analysis of the complete skeletons of Cretoxyrhina Show a fairly different animal from that of the great white shark. It has shown that it has a much shorter snout and bigger eyes, a kin to thresher and crocodiles sharks
