I think one reason why Pterosaurs become much larger and change their lifestyle at the late of Cretaceous because they were competing with birds that started to diverse. As you can see, there are small amount of mini Pterosaur that have similar lifestyle to Anurognathus or Nemicolopterus remained in late Cretaceous if not no at all. Small Pterosaurs seem to unable to co-exist with birds which start to have the same niche in environment. The Pterosaur that are large and has different lifestyle from birds such as those long term sea dwelling such as Ornithocheiroids and the land-dwelling predators such as Azhdrachoids don't suffer this fate. So, they are more common during late cretaceous. Correct me if I'm wrong however.

Not too sure about the bird assumption. Pterosaurs and birds of small size coexisted during cretaceous, for example in Jehol, and it doesn't seem one outcompeted the other. The rise of large pterosaurs (gigantic ones actually) might be simply attributed to better development of flying mechanics that allowed them to grow into sizes of Hatzegopteryx and such.

Let me explain I mean most of the pterosaurs were larger than 9 ft in wingspan from what I remember, but I might be wrong but still some of the most of them form the early Jurassic to the late Cretaceous were somewhat larger even though. Also Furka the animal we are talking about is not Agathonathus but it's Chinese(?) cousin the really long named one with a J that right now I do not feel like trying to name it off the top of my head. I think at the time if lived in china it would have Sauropods and Titanosaurids (maybe) around it to feed off of. (Not sure if it is true but I think the J one lived in China with Sauropod.) Then by awkward walking I meant if they walked like a bird it would walk awkwardly for itself being that birds were and are used to walking like a bird being completely balanced while Pterosaurs have their wings that were awkward in a sense. However Giraffe Pterosaur walking is less awkward for a standpoint. |

Lack of fossil evidence for Amphicoelias and Hatzegopteryx. And mammoth DNA is always torn apart by ice

Also, lack of Saurophaganax specimen.... Seriously, in Morrison, while Allosaurus are found numerous, only a few of this titan are found.... *Fear that this awesome Theropod with cool name is just an overweight, old Allo. *

I'm annoyed by the fact that each time a sauropod is claimed to be the biggest, it keeps getting shot down. Sauroposeidon, Bruhathkayosaurus, Amphicoelias: none are so widely accepted anymore to be as massive as originally estimated. At least the one thing we do know for sure is that the biggest sauropods still got very, very large by the standards of land animals. |

Still we'll never know who is the largest, since chances for finding mega-sauropod skeleton complete enough are just slightly higher than for invention of a time machine. |

Ah the two things I love most, Sauropoda and Allosauroids both equally monster like as the other. Both made each other evolve quicker and bigger, ah the evolutionary struggle is real. Actually I rather prefer to say that Sauropods were the largest species group to ever exist on earth currently from the start of life to current day not knowing what species would evolve in the future and how big they will get in the future. Why I say that is that Sauropods can range above the one hundreds where they outmatched the blue whale in length, however they do not match up to the weight of the whale which makes them even more outstanding. Also non of the sauropods where the biggest, they were the longest and tallest of animals to exist. So if anybody told me a sauropod could never walk on land I would prove them wrong by the facts that they themselves had hallow bones and they were somewhat in a fashion as in formed or made to support tons of weight, plus they were not as weighted as a whale but as a large construction unit for some of them, others a few elephants. |

The fact that almost everyone I know in real life has only heard of a very small handful of dinosaurs. Most of my friends can only name T. rex, Triceratops, Apatosaurus, Stegosaurus, Pteranodon, and Velociraptor. A few of my buddies know Allosaurus, Ankylosaurus, Quetzalcoatlus, Brachiosaurus, Spinosaurus, and Parasaurolophus, but that's about as many as anyone I've met can name. |

At least in your country you don't have to deal with people talking about the Dinosaurus rex... |

NOPE.And I think other ones are enough, people don't have to know about what they're not interested in.For example I'm not interested in cars and no-one rants at me because I can't name all parts of the engine. |

What makes sauropods really amazing is the tetrapod design flaw, the piping for good to reach the brain is doubled up, where in whales, because they have tiny necks is nothing, in a giraffe its 12 feet, but for a sauropod with a 30 foot neck, where talking about a 60 foot artery |
